Opinion
An appeal is taken by the State of California from a judgment in favor of plaintiffs Osborne and Aileen White which quieted title to 38 acres of valuable tidelands of Petaluma River (sometimes called Petaluma Creek). Tidelands are the “land lying between the ordinary high and low tide lines.”

v.
California Fish Co.,
I. The Case
At the point where Petaluma River flows over the subject tidelands two or three miles upstream from San Francisco Bay, the river historically has been subject to tidal action of the Pacific Ocean, and therefore constitutes tidewater. It is “an arm of the bay” and since 1853 has been declared by law to be a navigable stream. (Compiled Laws of California, 1850-1853, ch. CXCVII, p. 916; Har. & Nav. Code, § 104.) It has also been navigable in fact; as recently as 1965, according to a publication of the United States Army Corps of Engineers, January 1, 1967, *743 Water Resources Development in California, 1 305,000 tons of freight were carried on the river.
In 1870 one John Reagan filed an application for a patent to a “certain tract of swаmp and overflowed land being Salt Marsh Land in Sonoma County, lying and situate on the North side of Petaluma Creek being the Second Island below the mouth of San Antonio Creek.” The island had been topographically surveyed in 1860. The relevant portion of this survey is depicted as “Figure One,” page 744, infra. The typewritten markings have been added by us. It will be noted that the main channel of Petaluma River flowed (and still does) off the southwesterly shore of the island, and as indicated, the outlined area of the river which loops around into “Rush Creek” and “False Bay” traces the low tide lines. Also noteworthy is the fact that the island’s northerly, easterly, and southerly sides merge into shallow “saltmarsh tidelands.”
Reagan’s patent application was made under the authority of “An Act to provide for the management and sale of the lands belonging to the State,” Part II of which related to the sale and reclamation of “swamp and overflowed, salt marsh and tidelands.” (Stats. 1867-1868, ch. 415, p. 507—herein called “the Act.”) A condition of such a patent was that the aрplicant reclaim the land. The statutory cost to the applicant was $1.00 per acre. The Act provided that the county surveyor must .survey the desired land, his survey thereafter to be submitted for approval to the state’s Surveyor General.
As provided by the Act the Sonoma County surveyor thereafter surveyed the island in 1871, following which a record of the survey was submitted to the state Surveyor General for approval. It was called “Swamp and Overflowed Lands Survey No. 58” (hereinafter S & O Survey #58). S & O Survey #58 placed the starting point of its subject land’s boundary as “Beginning at a stake set in a bed of broken glass bearing N 59V2 W from the center cor [¿7c] to section 33 distant 2384 chs.” (The stake and the bed of broken glass have vanished with time; they cannot be found.) There followed 31 counterclockwise zig-zag calls of courses and distances, which finally closed the survey’s plat at the point of beginning.
Also on the recorded survey the county surveyor sketched the survey’s perimeter plat, its courses and distances, and its relation to Petaluma Rivеr and to sections 3, 4, 33 and 34, “Base and Meridian of Mount Diablo.” A copy of the survey’s sketch is to be found on “Figure Two,” page 746, infra. The survey’s plat, the river, and sections 3, 4, 33 and 34, *745 are as they appear in the original; for clarity we have superimposed certain captions and markings.
*744
*745 It will be noted that the survey’s plat is firmly anchored on its southerly side to the southerly line of section 3, and on its easterly side to the easterly line of section 3 and the southerly line of section 34. It will also be observed that the survey’s plat is bounded partially on the north by “Tide Land Corrected Survey No. 21,” and on all remaining landward sides by “Swamp and Overflowed Lands Survey No. 15.”
It is also notable that the starting point of the survey’s calls, the “stake set in a bed of broken glass,” was at the point of the most westerly projection of the plat, which was also one of the points of a southwesterly call of Tide Land Corrected Survey No. 21. And a comparison of the topographic survey of Figure One with the plat of Figure Two will disclose that much salt marsh tideland to the north and east, and probably to the south, was included within the limits of S & O Survey #58.
A patent to the land embraced by S & O Survey #58, executed by the state’s Governor, was issued to Reagan’s successors in interest in 1880. It followed exactly the calls and courses and distances of the survey.
Plaintiffs’ claim rests upon the 1880 patent. The disputed 38 acres of tidelands are somewhere in the area shown at Figure One immediately above the word “River.”
Firmly established at the trial was the fact that the boundaries of the many patents along the northeasterly bank of Petaluma River fitted together closely, somewhat on the order of the common jigsaw puzzle. They were tied into several sections, in our case the lines of sections 3 and 34, as established in relation to Mount Diablo Base and Meridian (see Figure Two). Plaintiffs’ witnesses generally conceded, indeed insisted, that the several patents “fit together,” that adjoining boundaries were “identical,” that “58 and 21 joined” and that they were “all part of one solid map,” the “whole figure (of which] is rigid, fits in there and there and goes on down around San Pablo Bay.” It is emphasized by the sаme witnesses that S & O Survey #58 closely dovetailed with its nearby surveys. They said “the entire area of the survey all fit together as described in the patent.” The contention continues in plaintiffs’ briefs on appeal; strangely, in light of the evidence produced and relied upon by them, they say, “The contention that Survey 58 can be moved around (and courses changed) so as to put its boundaries where one would like to see them is the kind of ‘surveying’ nonsense which has bedevilled this controversy from the beginning.”
*746 With the courses and distances of S & O Survey #58 fixed on the earth’s surface, the patent’s riverside boundary’s angular calls are found to approximately follow the ordinary high tide mark. The disputed tidelands are located outside of the patents plat.
This state of affairs would reasonably seem to indicate an intent of the county surveyor not to include this property in his survey. But plaintiffs’ expert witnesses Passarino and Robinson testified otherwise. From their involved studies they concluded that the county surveyor intended to *747 locate the subject tidelands within his survey lines. Passarino offered his own survey in which he had changed 22 of the 31 calls of S & O Survey #58. This amended survey went оut into the river and embraced the 38 acres of tidelands sought by plaintiffs. Robinson also made a survey. He testified that he positioned his survey in the same manner as did Passarino; he said “the two surveys [his and Passarino’s] do fit together.” Both witnesses testified that the altered surveys were as really intended by the county surveyor in 1871.
*746
*747 The changes of the survey lines which would add the 38 acres of riverfront tidelands to plaintiffs’ acreage may best be illustrated by a comparison of S & O Survey #58 with the Passarino survey. (We have shown the points of difference by heavy black type.)
County S & O Survey #58 Passarino Survey
Surveyor’s
Number Courses in Feet Courses in Feet
*748 It will be observed that the county surveyor’s calls numbered 26 through 31 constituted the common boundary of S & O Survey #58 with Tide Land Corrected Survey No. 21. Passarino’s alterations of this boundary would, of course, change the lines of Tide Land Corrected Survey No. 21, and deliver land covered by that survey to the plaintiffs, or to whomsoever now owns the northerly shore of the island. Later, questioned about this, plaintiffs’ witnesses said, “The only one that was not a fairly true fit was 58.” Unexplained was how Tide Land Corrected Survey No. 21 could in this manner be pushed northward without disrupting the lines of other patents, and they in turn, still others. As the witnesses had said, speaking of the area’s patent complex, “this whole figure is rigid, fits in there and there and goes down around San Pablo Bay.”
Passarino explained why he concluded that it was the county surveyor’s intent to meander the river’s ordinary low tide line. He said that S & O Survey #58 recited that 934.65 acres were contained within its delineations, while in fact it embraced only about 888 (or 850) acres. In order to reconcile this difference in acreage, the meander line “just has to go out to the low water, otherwise, the acreage is short.” So he had to go “outside the boundary described in the patent.” Since the patent’s nonriver boundaries were tightly fixed and could not be changed, the river’s low water mark “is the only place I know of that the area could be balanced, would have to lie in this area between the described patent line and the edge of Petaluma Creek.” He reiterated that he had moved the riverward boundary of S & O Survey #58 to the low tide line “as a result of determining the acreage” and for “thе purpose of computing acreage.”
Called to the stand again later in the trial Passarino repudiated his reason why he believed the county surveyor intended the river’s low tide line as the boundary of his survey. The following questions were asked and answers given. “Q. Now one or two more questions. In locating the southwesterly boundary of swamp and overflow Survey 58, that is running courses and distances in the survey, you paid no attention to acreage, did you? A. That’s right. This is entirely independent. This is the mathematic position of bearings and distances in the patent. Q. Without regard to acreage? A. That is right.” The new reason, “the mathematic position of bearings and distances in the patent” was never made clear; at least it is not made clear to us.
Passarino also gave the following testimony: “Q. Now there are located in this area between the line that you have marked A and the line that you have marked B, five swamp and overflow patents, are there not? 15, 62, 58, 45 and 35? A. Right. Q. And together with a tidelarid patent *749 21 encompassеs the entire area? A. Yes, sir. Q. And any of those, in any of them you plotted them all, have you not? In any of them did they use your ordinary high water mark as the outward boundary? A. No, they did not.”
Robinson testified to the same effect: “Q. Assuming the map to be accurate, you have examined all of the other surveys located in this general area? A. Yes, I have. Q. And plotted them, more or less? A. Yes. Q. Do any of these boundaries at any point purport to follow the mean high tide line as it appears on this map? A. No, they do not, sir.”
It bears emphasis that neither the survey nor the patent was uncertain or ambiguous; it was not so contended at the trial nor is it so contended here. This accord undoubtedly results from a recognition of the long-existing rule that a public grant’s angular calls of courses and distances bounding land fronting on tidewater (absent a contrary intent expressly shown by the grant), as a
matter of law
meanders the ordinary high tide line. (Civ. Code, § 830;
Hardin
v.
Jordan,
II. The Issue
Amplifying their concession that S l& O Survey #58 and its relаted patent are not ambiguous, plaintiffs now urge “that the problem before the lower court was not one of construing the patent or the survey but that of locating the boundaries recited in the patent and in the survey.”
Plaintiffs do not correctly state the issue before the superior court, and now before us. It is true that the issue was not “one of construing the patent or the survey” for the meaning of those documents was clear; their meandering riverbank courses and distances did not enclose the disputed tidelands, while their remaining calls neatly conformed to the boundaries of sections 3 and 34 and the adjacent surveys. (See Figure Two, supra.) But the issue also was not “that of locating the boundaries recited in the patent and in the survey.” Any attempt to locate or relocate those lines riverward *750 would dislocate several miles of fixed coterminous boundaries; the patent’s most easterly boundary would be wrenched from the line of section 3 leaving a sort of no man’s land of several hundred feet with a corresponding maladjustment all around the patent’s sides. Plaintiffs actually make no argument that they seek to move thе fixed plat of S & O Survey #58 to a different place on the earth’s surface; indeed they say that this is what one of the State’s theories would do-.
Plaintiffs would better state the issues posed by them as whether, without disturbing any of the present land coverage of the patent, certain of its boundary lines can be expanded outward to include an additional 38 acres of tideland. This would not be a locating of the patent’s boundaries; but rather an altering of some of them for the purpose of enlarging the area contained by all of them. No other possible interpretation can be given the revised courses and distances of Passarino’s and Robinson’s proffered surveys, and their testimony about going outside the patent’s boundaries in order to give effect, not to the county surveyor’s explicit recorded survey, but to his “intent.”
The issues might be even more simply stated as: (1) did the county surveyor intend to locate the riverward boundary at the low tide line (a question of fact), and, if he did so intend, (2) are the patent’s boundaries to be extended accordingly (a question of law).
III. The Findings
Resolving the issues, the trial court stated that it accepted Passarino’s “survey and positioning of S & O #58” (italics added) and then made its finding that: “The courses and distances of the sоuthwesterly boundary o-f the lands described in said patent were in the nature of a meander line and were intended to and did meander the ordinary low water line of Petaluma Creek on the northeasterly side thereof.” (Italics added.)
We have concluded that this finding is unsupported by substantial evidence, and that the judgment, on that factual ground, and on other legal grounds, must be reversed. Our reasons follow.
IV. The Intent of the County Surveyor
As must by now be clear, the trial concerned in its near entirety, not the actual fixed boundaries of S & O Survey #58 and the patent, but instead the intent of the county surveyor when he established those boundaries. Little heed was paid to the intent of the state in issuing the patent.
Under the Act the county surveyor was designated as the person to prepare a survey of the land sought to be purchased and patented under *751 its provision. (See § 23 of the Act.) He had no further function in the land patenting process. It was the state Surveyor General to whom authority to approve the survey was given (§ 10). Upon his approval and the applicant’s compliance with the Act, a patent was signed and issued by the Governor. (§ 10.) Elementary logic would seem to indicate that the land patented by the state was the land applied for and covered by the survey as recorded. Certainly the state may not reasonably, or legally, be considered bound by some undisclosed intent of the county surveyor to include additional land in his survey.
It is established law that the delineations of a . survey and state patent are the measure of the patent’s boundaries, and of the patentee’s (and his successor’s) rights. This is true even where the lines were intended to have been and should have been (as here contended) placed elsewhere.
“[A] patentee takes only such land as is included within the survey of the plot conveyed and he cannot later question the survey as erroneous, although in fact the line in question should have been placed elsewhere.”

Verdi Dev. Co.
v.
Dono-Han Mining Co.,
It follows that the superior court erred in adjudging that plaintiffs, basing their claim on the patent, took land thereby which was outside of the patent’s boundaries.
V. Civil Code Section 830, and the Common Law
As we have pointed out, while the patent does expressly grant certain salt marsh tidelands on its northerly, easterly, and southerly sides, it does not expressly grant the tidelands of the navigable river on its southwesterly side.
Another long-standing pertinent rule is that title to tidelands will pass to the state’s grantee only when the instrument of conveyance expressly so states on its face. Without such an express provision the grantee of lands facing on tidewater takes only to the ordinary high tide line.
The rule has been codified in California by the enactment of Civil Code section 830. This section, as pertinent here, provides: “Except where the grant under which the land is held indicates a different intent, the owner of the upland, when it borders on tidewater, takes to ordinary high water mark; . . .”
Section 830 is a codification of the common law rule. (See
Hardin
v.
*753
Jordan, supra,
As recently as February 1970, this state’s Supreme Court stated: “Among the statutory provisions favoring public ownership of shoreline areas is Civil Code section 830. That section states that absent specific language to the contrary, private ownership of uplands ends at the high water mark.”

The court continued (p. 655): “It is equally well settled that a grant from the sovereign of land bounded by the sea or by any navigable tide water does not pass any title below high-water mark unless either the language of the grant or long usage under it clearly indicates that such was the intention." (Italics added.)
Stillwell v. Jackson, supra, 5 Cal.2d 165, 169, holds that where an instrument grants land bounded by the meander line of the ocean’s shore, that “in the absence of any other declared purpose, a meander line thus drawn would represent the line of ordinary high tide of the ocean . . . .” (Italics added.)
Some confusion has been engendered by the use of language relating to the rule we have discussed. Thus, in
Abbot Kinney Co.
v.
City of Los Angeles,
*756
of Los Angeles
(1959)
We have been able to find no authority, and none has been presented, which purports to impugn the Civil Code section 830 and common law rule that unless a- public grant expressly states otherwise on its face, the grantee of land bounded by tidewater takes only to the ordinary high tide line.
Since the patent upon which plaintiffs rely did not expressly grant the tidewater on its southwestern boundary, it will be seen that the trial court erroneously failed to apply Civil Code section 830, and the corresponding common law rule.
VI. The Parol Evidence Rule
The trial court was presented with an unambiguous patent, the plat and courses and distances of which did not include the tidelands at issue. Parol evidence was admitted for the purpose of showing an intent by the surveyor that the additional 38 acres be enclosed. The trial court on the basis of the parol evidence found such an intent.
We recognize that this parol evidence was not objected to by the State of California; also we observe that no contention is made that the patent itself was on its face reasonably susceptible of an interpretation that the 38
*757
acres of tideland were included with the patent’s defined limits (see
Pacific Gas & E. Co.
v.
G. W. Thomas Drayage etc. Co.,
A complete but concise statement of the parol evidence rule as it relates to grants of real property is found in
Pinsky
v.
Sloat,
Referring to governmental patent grants, California’s Supreme Court has expressed the rule in this manner: “It is undoubtedly true, and supported by abundant authority, that when the description of a granted tract
*758
of land embraced within the terms of a United States patent is, upon the face thereof, clear and unambiguous, such description constitutes the final word, and in such case evidence will not be admissible to show that the grantor intended to do other than that thus clearly set forth upon the face of the grant”
(Broome
v.
Lantz,
The United States Supreme Court, adopting language of
Chipley
v.
Farris,
It follows that plaintiff’s extrinsic evidence of intent was irrelevant, and “as a matter of substantive law” could not serve to enlarge the boundaries of the unambiguous patent.
VII. Substantial Evidence?
We now inquire of the record whether there was substantial evidence in support of the trial court’s finding that in fact the county surveyor did intend to include the disputed tidelands.
The substantial evidence rule holds that when a court’s finding or a jury’s verdict is attacked on the ground that it is not sustained by the evidence, the power of an appellate court begins and ends with the determination whether there is any substantial evidence, contradicted or uncontradicted, which will support the verdict. Questions of credibility must be resolved in favor of the fact finder’s determination, and when two or more inferences can reasonably be drawn from the evidence, a reviewing court may not substitute its deductions for those of the trier of fact. If on any material point the evidence is in conflict, it must be assumed that the court or jury resolved the conflict in favor of the prevailing party.

v.
Bassett,
Applying the foregoing rules we must and do, and for the reasons we now state, conclude that quite apart from the applicable rules of law we have discussed there wаs no substantial evidence in support of the trial court’s critical finding of fact as to the county surveyor’s intent.
The Witnesses Passarino and Robinson
“[T]he weight to be given to the opinion of an expert depends on the reasons he assigns to support that opinion.”
(Gazzera
v.
City and County of S.F.,
We have closely studied the trial record of the witness Passarino’s testimony. It reveals that, although expressed many ways, the only reason given for his conclusion that the county surveyor intended the low tide line as his riverward boundary, was that it was “the only place where I know, in my opinion, that there is sufficient area to come anywhere close to the patent amount that was granted. . . .” This, it is now concéded, is entitled to no evidentiary weight whatever.
It is true that Passarino later withdrew that reason, saying that he had really “paid no attention to acreage”; instead, the “rеason” for his conclusion became “the mathematic position of bearings and distances in the patent’ without regard to acreage. But Passarino’s testimony nowhere suggests how, or in what manner, the “mathematic position of bearings and distances in the patent” could or did reasonably indicate the county surveyor’s intent to draw his southwesterly lines other than as he did.
Passarino’s opinion evidence was no better than his reasons for it, it was not substantial evidence.
We now consider the testimony of the witness Robinson, a title insurance company employee. Unlike Passarino he said he was not “too concerned with acreage.” Preparing to testify about plaintiffs’ riverward boundary he began looking through “title records seeking old deeds.” He came to “the conclusion’’ that a point by Lakeville Road (apparently several miles from the island) “was a reasonably good position” to start. So he said, “I started searching, going back and forth until I found the line here that seemed to line up with my record.” He was led to “believe that [his] positioning was relatively close to what the people had been doing with the land.” He then “plottеd in the rest of the S & O’s and there is where it fell, somewhere in the vicinity of this line [the river’s low-water line].” In his computations he “did find errors that would cause [him] to shift one way or another and [he] did try to reconcile them [apparently without success].” Things “didn’t quite ft here or there, and the dimensions were minor, 10 or 20 or 50 feet, something of that nature.” One of the *761 errors appears to have been where the Petaluma Rancho line on which he relied “doesn’t meet.” The errors apparently presented little difficulty for the witness said, “I just allowed errors to fall there” at the river line. All of this caused him to “feel now [I am] relatively close to where I believe the original surveyor must have set his corners.” (The italics of this paragraph are ours.)
The last mentioned guarded statement of the witness seems particularly interesting. After his ambiguous meanderings from a point several miles away during which he resolved all perplexing questions in favor of plaintiffs, he “felt” he was “relatively close” to where he “believed” the surveyor “must” have set the line. Since we are dealing with the “relatively” short distance between the island’s low and high tide lines, after the witness’ study of several miles of uncertain courses and distances, the witness was also “relatively close” to the island’s high tide line.
Continuing his testimony, the witness said it “would appear to me that [the county surveyor] was working out to the visible water as it would normally be used by a boat,” and that other “people were visibly looking at the creek and that he, perhaps, did also.” The witness concluded that the original surveyor “was attempting to follow what appears to be the main channel of the Petaluma Creek” where the water was “6, 12 and 18 feet” deep and well beyond even the low tide line. (Italics added.)
If one were to consider credible this witness’ conclusions based upon such a pyramiding of uncertainties, he must go further; he must also believe that the State of California by its reclamation patent demanded the reclamation of a river, navigable by law and in fact, to a point somewhere in the deepest part of its “main channel.” A similar patent on the other shore followed by the required reclamation would have resulted in the damming of the river, or at least a 2-mile long sluiceway in which its waters would be narrowly confined.
But the most surprising feature of Robinson’s testimony is that despite the great effort he put into the case to find and fix the “true boundaries” of S & O Survey #58, except for the riverward boundary, he did not changе them at all. The northerly, easterly and southerly boundaries remained exactly where the county surveyor had placed them, firmly integrated with section lines and coterminous boundaries of other patents. He, as had Passarino, changed and extended the county surveyor’s lines out into the river where they enveloped the 38 acres of tidelands. His “survey” was the same as Passarino’s. And try as one will, no understandable or logical or credible reason can be found in his testimony why he concluded that the county surveyor intended, but failed, to place the survey’s boundary *762 at the low tide mark. As said in Herbert v. Lankershim, supra, 9 Cal.2d 409, 471-473, it is not “mere swearing” but “swearing creditably” that is supportive of a trial court’s findings and judgment.
The testimony of the witness Robinson also, does not rise to the level of substantial evidence.
Three additional facets of the evidence relied upon by plaintiffs should be discussed at this point.
Boundaries of Nearby Patents
The trial court seemed to give some significance to the testimony of Passarino and Robinson concerning boundaries of nearby patents, particularly the adjoining Tide Land Corrected Survey No. 21 and Swamp and Overflowed Lands Survey No. 15. (See Figure Two, supra.) Passarino testified that the high tide line was not used as the boundary on any of the patents. Robinson agreed; he said he had examined “all of the other surveys in this general area” and that none of them purported “to follow the mean high tide line.”
Tide Land Corrected Survey No. 21, with the exception of the “False Bay” area beyond the low tide mark (see Figure One, supra), covers tidelands (salt marsh tidelands) in its entirety. This is undoubtedly why it is characterized as a “Tide Land” survey instead of “Swamp and Overflow” as is S & O Survey #58. It is crystal clear to all that this survey, as the witnesses testified, does not follow the high tide line.
But for some reason, or perhaps no reason, the remaining contiguous survey and patent (Swamp and Overflowed Lands Survey No. 15, issued in 1883) were not offered in evidence at the trial. After affording each “party reasonable opportunity to meet such information” (see Evid. Code, § 459, subd. (d)), we have taken judicial notice of this patent, an act of the chief executive officer of the state, the Governor. (Evid. Code, § 452, subd. (c).) This patent (as does the survey on which it is based) defines its southwesterly boundary as
“thence ... to Petaluma Creek; thence along the same in a southeasterly direction to a point”
where the boundary line again turns inland. Under established rules of our law, such a boundary is the
high tide line
of the river. (Civ. Code, § 830;
Martin
v.
Waddell, supra,
The witnesses’ testimony as to the other nearby patents was obviously based on the “intent” of the surveyors rather than on the lines as drawn, as *763 was their testimony concerning S & O Survey #58. Although these surveys were in evidence Passarino and Robinson made no attempt from them or otherwise to explain or verify their conclusion. And our examination of the documents reveals nothing to indicate a meander of the river’s low tide fine, any more than does S & O Survey #58.
The record suggests that the witnesses knew their testimony that none of the nearby patents used the high tide line as a boundary, at least as to Swamp and Overflowed Lands Survey No. 15, to be incorrect. The southernmost riverside course, “call 16,” of Passarino’s survey (concurred in by Robinson) was turned abruptly from the river’s low tide line toward the high tide line of the land, where after joining an easterly “call 17” it intersects with the riverbank boundary of Swamp and Overflowed Lands Survey No. 15 above the high tide line. If the witnesses’ survey had been consistent with their testimony the point of intersection would be at the low tide line of the river, at which level the neighboring patent’s boundary would continue on downstream.
Little probative value attended the conclusions that none of the nearby patents’ boundaries followed the ordinary high tide line.
The Patent’s Acreage
As’ we have seen, Passarino’s conclusion as to the county surveyor’s intent was initially based on his (Passarino’s) assumed need to bring the patent’s designated acreage (934.65 acres) closer to that which was actually enclosed by its boundaries. He had explained that he had to “go out of the [patent’s] boundary line” to bring the acreage “reasonably close to the area that was in the patent.” He reasoned: “The only place that I know of that the area could be balanced, would have to lie in this area between the described patent line” and the “low water mark” of the river. That, he said, “is the only place where I know, in my opinion, that there is sufficient area to come anywhere close to the patent amount that was granted.” He agreed with plaintiffs’ counsel that the true line “just had to go out to the low water, otherwise, the acreage is short.” Based on these and other considerations he concluded that the county surveyor in 1872 was really meandering the “channel and low water mark” although the courses and distances of his survey indicated otherwise.
Although the witness later changed this testimony, saying in response to a leading question that he “paid no attention to acreage,” the trial court in its notice of intended decision stated that it was nevertheless an “aspect of the case to be considered.”
Few principles of our law are as settled as the “invariable rule,
*764
early adopted in this state, ‘that when a piece of land is conveyed by metes and bounds, or any other certain description, all included within those bounds, or that description, will pass, whether it be more or less than the quantity stated in the deed. . . . The quantity being the least certain part of the description must yield to the boundaries or numbers, if they do not agree.’ ”
(Gragg
v.
Culp,
The many authorities on the point are summarized in 8 Cal.Jur.2d, Rev., page 824, as follows: “In land measurement, quantity is the least reliable of all descriptions, and, in the absence of anything disclosing a different intention, a statement of the quantity of land conveyed by a deed does not prevail over a clear description of the boundaries of the tract. Even where the quantity of land to be granted is specifically stated, this amount cannot be made up by the grantee by running his boundary lines differently from lines clearly described and easily ascertained from the deed.”
Even without consideration of this rule it is difficult to place any probative weight in the instant case on the recited acreage of 934.65. The figure was obviously an unsuccessful attempt of the сounty surveyor to compute the acreage within his 31 calls of courses and distances. It is inconceivable that he would attempt to determine area, to hundredths of an acre, in the unmeasured and unbounded spaces of the river between high and low tide lines, and beyond the survey lines he had established. It is worthy of note that, even in this age of calculating machines, none of the witnesses at the trial was able to definitely fix the acreage within the fixed boundaries of S & O Survey #58. Although it obviously can be reached with mathematical exactitude, they arrived at varying conclusions of “approximately 880,” “between 880 and 883,” “in round figures 888” and “850 more or less.”
In any event plaintiffs now concede that the evidence of excess acreage has no probative value whatever. In their briefs they say: “. . . there is no question that a recital of excess or shortage in acreage is, not grounds for altering the boundaries in a patent”; and that they have “never suggested before this court or the lower court that the fact that the pеrimeter description of the survey encompassed fewer acres than are recited in the patent should or could have any bearing upon the location of the southwestboundary of the survey.”
*765 The County Surveyor’s Plat
Plaintiffs also rely on the county surveyor’s perimeter plat (Figure Two, supra) adjacent to which is sketched the river. They contend that it clearly shows the boundary as running along the river’s main channel at the low tide level. We do not think that such an interpretation is reasonably permissible.
The plat shows Petaluma River to closely follow the county surveyor’s jagged calls along the irregular high tide line of the shore. Figure One, q.v., and other early days surveys in evidence, clearly establish the river’s low tide line, at the side of its main channel, to be a sweeping gently curved line, wholly unlike the surveyor’s serrated line at the water’s edge.
Whatever probative value , is to be found in the depicted relation of the plat of Figure Two to the adjacent river, it tends to support the State of California’s case.
We have discussed all of the points of evidence which are contended by plaintiffs to be supportive of the trial court’s findings and judgment. But in our overall determination of the nonexistence of substantial evidence, other considerations are of importance.
Other Considerations
1. By any reasonable standard S & O Survey #58 itself would seem to be the most persuasive evidence of what land the surveyor intended to cover.
2. As pointed out, the starting point of S & O Survey #58 and of one of its riverside calls was a stake set by the county surveyor “in a bed of broken glass” at the extreme westerly prominence of the survey. (See Figure Two, supra.) If plaintiffs’ contention as to the low tide line situs of the surveyor’s intended courses and distances be accepted, it would follow that he intended to and did place this land monument out in the stream bed where it would almost continuously be covered by the ocean’s tidal waters. (See Figure One, supra.)
3. The clear purpose of the Act was to encourage the reclamation and use of certain of the state’s “swamp and overflowed, salt marsh and tidelands.” The evidence establishes that the immediate successors in interest to Reagan’s rights, fulfilling their obligation to reclaim the patented land, did not reclaim the tidelands here at issue. Instead they constructed a levee near, but landward of, the river’s high tide line, thus eliminating the tidelands from their reclamation plans. This strengthens the inference that the tidelands were neither included, nor intended nor believed to be
*766
included, in the state’s 1880 patent. It was not until many years later that plaintiffs’ more immediate predecessors built another levee at the river’s low tide line. If a conveyance is open to construction as to the extent of the grant “the most reliable circumstance in aid of such construction is the practical construction given it by the acts of the parties” during the years immediately following its execution.

v.
Conroy,
4. The evidence shows that the several successive grants of S & O Survey #58 land following the 1880 patent (apparently 10 in all, including the grant to plaintiffs) describe the riverward boundary as the
“bank”
of Petaluma Creek. None recites the 'county surveyor’s meandering courses and distances on the river’s edge, and none refers to a boundary at low tide line. The
bank
of a river is that which “ ‘contains the river in its natural channel when there is the greatest flow of water.’ . . .”

v.
Meiners,
5. As we have indicated the only
upland
patent adjoining S & O Survey #58 was that of Swamp and Overflowed Lands. Survey No. 15, to the east and south. The latter patent was issued by the state in 1883. This patent expressly ran “along' Petaluma Creek” which, since tidal waters are involved, as a matter of law was the river’s high tide line. “When tide water is the boundary, the rights of the grantor to ordinary high-water mark are included in the conveyance.” (Code Civ. Proc., § 2077, subd. 5; see also Civ. Code, § 830;
Bouchard
v.
Abrahamsen, supra,
6. Civil Code seсtion 1069 provides: “A grant is to be interpreted in favor of the grantee, except that a reservation in any grant, and every grant by a public officer or body, as such, to a private party, is to be interpreted in favor of the grantor.” (Italics added.) While in the case at bench the *767 patent grant is admittedly unambiguous, the obvious public policy behind section 1069 would seem to call for application of its rule to the dispute here over the “location” of one of the grant’s boundaries.
7. And, of course, upon the plaintiffs rested the burden of proving title to the subject tidelands.
(Ernie
v.
Trinity Lutheran Church,
It becomes unnecessary to our disposition of this appeal to consider the State of California’s conditional contention that in any event the state, in granting the patent based on S & O Survey #58, retained an easement in Petaluma River’s tidelands for the purpose óf commerce, navigation, and fisheries.
The judgment is reversed; the superior court will enter judgment quieting title to the disputed tidelands in the State of California.
Molinari, P. J., and Sims, J., concurred.
This is the starting point of the county surveyor’s calls, the “stake set in a bed of broken glass.”
