TARLTON, Chief Justice.

This appeal is from a judgment wherein the appellee, as plaintiff, recovered from the appellants, as defendants, 308 acres of land lying in Wichita County. His claim rests upon a location made July 20, 1886, by virtue of Confederate certificate number 655, issued August 27, 1881, to Lewis Coleman, for 1280 acres.

The appellants claim by title derived from the heirs of Samuel C. Anderson, to whom a patent was issued August 4, 1877.

The appellee contends that his location was upon a vacant strip situate between the east line of the Samuel Anderson survey and the west lines *355 of the Columbus Tap Railway Company surveys, numbers 1 and 2, which lie contiguously, the one north of the other; and the sole question for our consideration is, whether, in the light of the record, there was such a vacancy at the time of the Coleman location.

The course of the south line of the Samuel Anderson survey is “ east 1866 varas to the west line of the Columbus Tap Railway Company survey number 2; thence north 3670 varas to the northwest corner of the Columbus Tap Railway Company survey number 1.”

While the west line of the two Columbus Tap Railway Company surveys is an unmarked prairie line, its location is nevertheless undisputed, and the inference to be irresistibly drawn from the field notes of the Coleman survey is, that the appellee admits it practically to be where the appellants claim that it is.

When the surveyor of the Anderson tract tells us, as he does in the field notes thereof, that the east line of that survey and the west line of the Columbus Tap Railway Company surveys are coincident, we must presupie that he tells the truth, and that this statement is founded upon an actual survey made by him. The line thus called for, and with its locality, as in this instance, fixed and acknowledged, becomes, though unmarked, an “ artificial object,” controlling course and distance. Maddox v. Fenner, 79 Texas, 279; Groesbeck v. Harris, 82 Texas, 415.

The presumption referred to is, of course, disputable; and its effect may be avoided by proof that the challenged call was made by mistake. In this case, however, the testimony, as we interpret it, sustains the theory of an actual survey, and excludes that of mistake or conjecture.

Without stating other reasons leading us to this conclusion, it suffices to say, that accepting appellee’s theory, the Samuel Anderson survey would violate its call requiring its west line to course with the east line, thoroughly fixed and identified, of the older Rivers survey, and in its western course to conflict with the latter survey to the extent of a strip 390 varas wide and 2726 varas long. Accepting, on the contrary, the appellants’ theory, the calls of the Anderson tract harmonize quite satisfactorily with those of the surrounding surveys.

We think that the verdict of the jury, finding the existence of a vacancy between the Anderson survey and the two Columbus Tap Railway Company surveys, .is contrary to the manifest weight of the testimony, and that the trial court should have sustained the defendants’ motion for a new trial, urging the grounds above set out, and included substantially in their fourteenth assignment of error.

We decline to consider appellants’ proposition, to the effect that appellee failed to establish title, even conceding the existence of the vacancy. This proposition rests upon an assignment that “ the court erred in refusing to give the three special instructions requested by defendants, *356 numbered 1, 4, and 6.” Such an assignment, the instructions requested bearing upon different and distinct issues, is too general to require notice.

Delivered October 26, 1893.

For the error pointed out, the judgment is reversed and the cause is remanded.
