The demandants in this action move for a new trial on account of a misdirection of the Judge in a matter of law to the jury ; by which they were instructed that “iftheybeliev- “ ed the demanded premises were within fifteen miles of Kenne-u bee river, measuring in any direction, or on any point of compass “ from the river, they ought,to find their verdict for the deman-u dants.” It appears from the evidence reported by the Judge, that the demanded premises are within fifteen miles of Kennebec river, measuring in one direction ; but that they are not within fifteen miles of the river, measuring upon a west-north-west course.

It is conceded that the land of the proprietors of the Kennebec purchase extends fifteen miles from the river, on each side ; and that the determination of this cause will depend upon the course upon which this distance of fifteen miles is to be measured.

The counsel, for the demandants contend that it is to be ascertained by measuring in any direction, from any part of the r.iver within their limits. On the other side it is insisted that this distance is to be ascertained by measuring at all points, at right angles with the general course of the river, which, as the counsel for the tenant assume, would require an admeasurement upon a west-north-west course. And they insist that their position is supported by the true construction of the original title of the demandants ; by their actual grants and locations ; by their deeds ofreleasetothe Pejepscot proprietors,, ascertaining a part of the southerly line of their claim; and by the adjustment made b etween them and the Commonwealth of Massachusetts, by which their title was confirmed within certain limits.

We are met at the threshold of this controversy by a decision of the Supreme Judicial Court of Massachusetts, in the case of the Pejepscot proprietors, under whom the present tenant claims, and *115Zadock Bishop, cited by the demandant’s counsel, but not to be found in the reports, which they contend, determines the question in favor of the demandants. Upon examining the case cited, as reported by the Judge who presided at the trial, it appears that the tenant claimed under the proprietors of the Kennebec purchase ; that the land in dispute would not be included within their claim, measuring the fifteen miles upon a west-north-west course; but that it was within fifteen miles of the river measuring upon a course at right angles with the river, and probably meaning according to its direction at the place from which the admeasurement was made. The Judge instructed the jury that the proprietors of the Kennebec purchase had a right to extend their grant fifteen miles from the river, to be measured on a course at right angles with the river in every part; and that if they believed that the land in dispute lay within fifteen miles of the river, measuring in any direction, they must find their verdict for the tenant, which they accordingly did. To this opinion and direction of the Judge the demandants excepted, and moved for a new trial on account of a misdirection in a matter of law. This motion having been argued in the county of Kennebec, and having been continued nisi, the Supreme Judicial Court, at November term 1819, in Middlesex, directed the clerk of the county of Kennebec to enter upon the , docket of the preceding term of that county that the motion for a new trial was overruled, and ordered judgment to be rendered upon the verdict.

From the record and proceedings in the case cited, it would seem that the whole Court sustained the opinion given by the Judge to the jury ; but the counsel for the tenant in this action having produced a letter from one of the Judges of that Court, stating that no general principle of construction was settled, or intended tobe settled in that cause, I have deemed it suitable and proper to go into a full consideration of the general question raised between these parties.

It may tend to a more satisfactory elucidation of the question, to consider, first, upon what principles the claim of the deman-dants ought to be settled, independent of any actual locations made, or agreements entered into, by them ; — and secondly, how far their rights may have been affected by such locations or agreements.

*116The original grant from the council established at Plymouth, of the lands now claimed by the proprietors of the Kennebec purchase, after fixing the points in Kennebec river above and below, to and from which it was limited, extended it for “the space of fifteen English miles on each side of the said “ river, commonly called the Kennebec river, and all the said “ river called the Kennebec that lies within the said limits and “ bounds, eastward, westward, northward and southward.”

The difficulty in ascertaining the extent of the grants on each side of the river, arises from the winding and serpentine course which rivers and streams are uniformly found to pursue.

By measuring the fifteen miles at every point, at right angles with the general course of the river, upon the hypothesis contended for by the counsel for the tenant, the tw,o sidelines would very nearly correspond with the particular course of the river in all its parts, and the end lines would be at right angles with the general course, and parallel with each other.

The lines ascertained in this manner would embrace about the same quantity of land which the grantees would have been entitled to, had the river proceeded in a straight line between the points to which their grant is limited ; — and if we assume that the distance between these points in a straight line is twenty miles, but that as the river runs it is twenty five miles ; this rule of construction requires that a given space projected from a meandering line'of twenty five miles would embrace no more land than would be included in the same space projected from a straight line of twenty miles. It is demonstrable, however, that if you pass the end of a line of the given space in length, along the meandering base, and, without withdrawing it in any part therefrom, with the opposite end mark an exterior line, keeping the measuring line always upon an inclination which will give such exterior line its greatest extension ; the land embraced will be much more than the same measuring line would include, extended in the same manner along the straight base. And from every point in the exterior line you would reach the winding base in the given distance, and from every point in the same base you would reach the exterior line in the given distance, in some one direction.

*117The position in favor of the tenant’s mode of admeasurement, the force of which I have felt most strongly, is — that every rod in the given base, which is the river, should determine the location of the same space in each of the exterior lines ; the only practicable way of doing which would seem to require his construction. But the land conveyed was to extend the space of fifteen miles on each side of the river, which is equivalent to saying that it is thus to be extended from the whole and every part of each side. If therefore, extended from some points in the river, the line 'of fifteen miles would not include so much land as if extended from other points ; yet, as all points are equally given, I can perceive nothing which would preclude the grantees from measuring from such points as would be most favorable to them. And upon a full consideration of the question submitted, I am of opinion that the terms of the grant are best satisfied by extending it so as to embrace, all the land which can be found within fifteen miles of the river, measuring from any point, in any direction, not above or belovr the points of limitation.

With regard to the end lines of the grant or patent, it appears to me that they should be formed by an admeasurement at right angles with a straight line extended between the points within which the grant is limited; or, in other words at right angles with the general course of the river. For the grantees are entitled to no land above or below these points of limitation ; and whether land be above or below these points will depend on the direction in which they lie in relation to each other. The general construction before given is supported by the case of the Pejepscot proprietors against Bishop ; although, for the reasons before stated, I have not considered that case as decisive of the present. I have not been able to find, among the reported cases of Massachusetts, any one wdiich has presented a question like that raised between the parties before us. In New-York, the true location of grants of a determinate breadth, extending along a river or stream, has frequently been submitted to their judicial tribunals ; and in one instance, the Courts there were called on to determine the construction of a grant extended for a given distance around certain plains, and wrhich was considered as presenting the same question, in principle. In the case of Jackson *118v. Lunt 2 Caines 363, Staat’s patent was under consideration ; which was to run up the Hudson as the river runs, from a certain point, two hundred chains ; thence up into the woods, north-west, twenty chains, to the mountain'; thence along said mountain, parallel with Hudson’s river, to a certain rivulet, thence down that rivulet to the place of beginning. Spencer J. in delivering the opinion of the Court, observed that in running a line parallel with a river, it is only requisite that the distance where that is to control should be such that the river in some one point is not further off than is required. In other words, the west line of Staats’ patent, without reference to the mountain, if run parallel with the general course of the river, might in some places be at a greater distance than the twenty chains, and yet be correctly run.

In Williams v. Jackson, before the Court for the correction of errors, 5 Johns. 489, the locatiop of the Hoosack patent was in controversy,which extended for two miles on each side of Hoosack creek. He Witt Clinton, senator, in delivering his opinion, in which a majority of the Court concurred, states that “ the mode “ now adopted by the State, and considered the only practicable u one in cases like the present, is to run the bounds so that every point in them shall be exactly the given distance from the point u nearest to it in the creek or river.” The same rule prevailed in the location of the Catskill patent, 5 Johns. 440, which was to extend four English miles from five great plains of an-irregular figure. It seems therefore that the construction upon which the demandants rely, and which appears to me to be the true one, is in conformity with that which prevails in New~York.

It remains to consider whether the proprietors of the Kennebec purchase have done any thing in their locations, or in their agreements with the owners of adjoining tracts, impairing their right to the full benefit of this construction. They have located their lots uniformly, it is said, upon a west-north-west and an east-southeast course ; which, it is contended, is at right angles with the general course of the river. As these lines would be parallel with their end lines, there was a manifest propriety and convenience in this location; and I can perceive nothing in it which can have any tendency to curtail their western boundary. Nor *119can I discover that their western line was limited or restricted by their deed of release in 1758 to the Pejepscot proprietors. By that deed a part of their southern boundary was to run “ a west- “ north-west course, until it meets with the westerly line of the “ Kennebec purchase as it extended north and south, and which “ is fifteen miles from said Kennebec river.” In legal construction, this line would run a west-north-west course to the westerly line of the Kennebec patent, as a monument, wherever that might be, whether exceeding or falling short of fifteen miles. And although that line is represented as being fifteen miles from the river, yet that representation would be true in fact, if it was found to be so, measuring in any direction.

The adjustment between the proprietors pf the Kennebec purchase and the Commonwealth of.Massachusetts, was a matter of compromise and compact ; to which the Pejepscot proprietors, under whom the tenant claims, were neither parties nor privies. But if it were otherwise, and we were now called upon to settle the demandant’s claim upon the principles of that adjustment, I am not aware that the limits of the Kennebec purchase would be curtailed by it. By the release from the Commonwealth, the westerly line of the Kennebec purchase, within the limits of their original patent, was to keep the distance of fifteen miles from the river, and that, upon a true construction, as we have seen, would not be done, if any point in that line approached nearer than fifteen miles to any point in the river.

Upon the whole, it appears to me that the demandants are entitled to judgment on the verdict ; and I am authorised to say that Judge Preble concurs in the result of this opinion.

Note. The Chief Justice, having formerly been of counsel for one of the parties, did not sit in this cause.
