Plaintiffs in error, R. P. Halbert and his son R. A. Halbert, herein called appellants, owned surveys Nos. 130,131, and 132 in block B, H. E. & W. T. Ry. Co. lands in Sutton county. The defendants in error, Mrs. J. A. Ward and her son, J. A. Ward, Jr., herein called appellees, owned surveys Nos. 125, 126, and 127 in the same block. The east boundary of the appellants’ surveys and the west boundary of the appellees’ surveys is a common line.
It is conceded by appellees that appellants have title to surveys 130, 131, and 132, and by appellants that appellees have title to surveys 125, 126, and 127. The questions of limitations were abandoned, and the action; resolved itself into a boundary suit to determine the location of the common line between appellants’ and appellees’ said surveys.
The appellees alleged that R. E. Halbert and the owners of other near and adjacent lands in said block, together with themselves, entered into an agreement by virtue of which it was decided that J. A. Simpson, county surveyor of Tom Green county, and a licensed land surveyor of the state of Texas, was selected and authorized by the owners to survey and locate on the ground the lines and corners of all. the surveys constituting the west portion of said block. They alleged the names of the parties to the agreement and the lands owned by each; that, in pursuance thereto, J. A. Simpson was employed about the 11th day of January, 1930, to survey and mark:-the boundaries and corners of the various sections covered by the agreement; that on January 26th thereafter, in pursuance to the agreement theretofore had, the parties, for the purpose of approving the correctness of the work and to show their acquiescence in, ratification, and adoption thereof, expressed their satisfaction therewith in writing in the form of a letter written to the commissioner of the general land office; that subsequent to the execution of said letter or agreement the general land office approved the work of J. A. Simpson in said block, and issued patents to the owners of one or more of the surveys according to the lines and boundaries determined by the said Simpson; that the agreement relative to the location of the boundary lines was binding, and the appellants, having acknowledged such agreement, approved and acquiesced in the work thereunder, estopped themselves from denying the effect of such boundary agreement or the location of the common line by the said Simpson between the sections owned by themselves and appel-lees.
At the close of the testimony, in response to a peremptory instruction, the jury found for appellees, and judgment was entered that appellants take nothing by their suit; that the line in controversy be established as located by Surveyor Simpson; that Mrs. J.' A. Ward have judgment for the 338 acres of land in controversy, and $546, with interest thereon, as the reasonable rental for the time said land had been unlawfully held by appellants. This judgment is before us for review.
The appellants challenge as error the action of the trial court in directing a verdict for the appellees.
The litigants concede, and the record discloses, that the trial court directed a verdict in favor of appellees because he was of the opinion that a boundary agreement had been made which under the uncontroverted facts and circumstances bound the appellants.
The appellants say in their brief that the statement of facts contains 367 pages, and it is therefore impracticable to give even a synopsis of the testimony bearing on the disputed issues. We concur in this statement, and will not undertake to recite the testimony in detail.
The uneontradicted evidence is that the location of the lines and corners of the surveys in block B were doubtful and uncertain ; that several surveyors had placed them in different positions; that none of such surveys had been approved or accepted by the land commissioner, who refused to issue patents to the surveys on the lines as located by any of said surveyors.
Some of the owners desired patents, and in 1928 B. M. Halbert, Arthur Simmons, and Surveyor Saunders visited Austin, consulted with the commissioner of the general land office relative to securing patents, and on their return B. M. Halbert advised R. E. Halbert and others that the lines between the surveys as previously located would not be accepted; that the commissioner had advised him, if the owners'would get together, select a surveyor, and agree to abide by the result of his work and have the lines run from a certain corner and a report thereof made to the commissioner, such agreement and survey would be recognized; that subsequent thereto Mr. Simpson was employed to run the lines, and the parties mutually agreed to abide by the result of his work, and later advised the commissioner of the land office of such work and agreement in the following instrument:
“Sonora, Texas, Jan. 28, 1930.
“Mr. J. H. Walker, Land Commissioner, Austin, Texas.
“Dear Sir: Mr. J. A. Simpson has been doing some surveying for us in Block B, H. *164E. & W. T. Ry. Co. in Sutton County, west of Sonora, .as per Mr. Robinson’s and your instructions to Mr. E. C. Saunders and B. M. Halbert on tbeir yisit to tbe land office in October, 1928.
“Viz: To commence at tbe Northwest Corner of Section 85, and tbe Northeast Corner of Section 92, in said block, made by John McNicol and run our lands out.
“We know and believe tbe work of Mr. Simpson is correct and satisfactory to all of us, and we ask for its acceptance and approval. Each of us owning tbe lands in Block B set opposite our respective names:
“Respectfully,
“Mrs. J. A. Ward, Sections 92, E ½ 101, 93, 100, 109, 116, 125, 126, 115, 127 and 114.
■ “J. A. Ward, Jr., Sections W ½ 101, 108, 117, 118, 107.
“ITred & Joe Berger, Sections 102, 91, part 86.
“B. M. Halbert, Sections 122, 123, 124, 133, 134, 135, 138. 139, 140.
“Arthur Simmons, Sections 121, 136, 137.
“R. P. Halbert, Sections 132, 141, 142, 131, 143, 130.
“B. M. Halbert, (Holds under contract to purchase from H. P. Cooper Estate, subject to approval of title and Probate Court), Sections 119, 106, 103, & 90.”
Tbe field notes of tbe surveys as made by Mr. Simpson were approved, and tbe commissioner issued patents to several sections by virtue of said survey and agreement. The appellants and appellees knew Mr. Simpson began his work at tbe northeast corner of section 92 and the northwest corner of section 85, and assisted in and observed tbe surveying while it was being done. Each of tbe parties to tbe agreement testify to the facts and circumstances relative to tbe making thereof and tbeir agreement to abide by tbe result of Mr. Simpson’s survey.
R. E. Halbert in bis testimony states that be agreed with the others as to tbe location of tbe corners, agreed to adopt tbe survey, and signed tbe instrument sent to tbe land commissioner.
R. A. Halbert did not sign tbe letter, and was not a party to tbe agreement, but be testified that be acquired bis interest in tbe land in controversy from his father in October or November, 1930; that he acted as chain bearer during tbe surveying done by Mr. Simpson; that be represented bis father, and bad full knowledge of tbe arrangements.
Tbe record shows that, after tbe work bad been accepted by tbe parties and approved by tbe land commissioner, tbe appellants became dissatisfied, but failed to secure a cancellation of the agreement by tbe consent of tbe parties thereto.
Appellants contend that tbe letter signed by tbe owners and sent to tbe land commissioner did not, in law, constitute a valid boundary agreement, and oral testimony was not admissible to vary tbe terms of said instrument, because there was no allegation of fraud, accident, or mistake.
These propositions may be conceded, but it does not follow that tbe court committed reversible error in directing a verdict against appellants.
Tbe appellees pleaded, in effect, that a boundary agreement was made by tbe parties, a surveyor employed, and the surveying done, and thereafter tbe letter was written to the land commissioner expressing their satisfaction with tbe agreement and the work done. This letter does not purport to contain the terms of the boundary agreement theretofore made, but advises tbe commissioner, in substance, that, according to bis instructions, Mr. Simpson bad been employed, bad surveyed tbeir lands, beginning at tbe northeast corner of section 92 and tbe northwest corner ef section 85, in block B, as made'by John McNicol; that they be- ■ lieved and knew tbe work to be correct and satisfactory to all of them, and asked that such work be accepted and approved.
If a writing is incomplete on its face and not intended to express the entire agreement, “parol evidence is admissible to make it complete by showing a separate oral agreement which concerns matters as to which tbe writing is silent and which is not inconsistent with its provisions. It is not necessary in such circumstances to allege fraud, accident or mistake in order to permit of tbe introduction of parol evidence as to tbe real contract. * * * This principle is not inconsistent with tbe rule excluding contemporaneous parol evidence to contradict or vary tbe terms of tbe writing; tbe evidence does not contradict or vary the writing, but is consistent with it.” 17 Tex. Jur. § 366, p. 817 et seq.; Magnolia Warehouse & Storage Co., Inc., v. Davis & Blackwell, 108 Tex. 422, 195 S. W. 184; Pierce v. Allen (Tex. Civ. App.) 278 S. W. 453; Morgan v. Steinberg et al. (Tex. Civ. App.) 23 S.W.(2d) 527; Higginbotham Cattle Co. v. Whaley & Lewis et al. (Tex. Com. App.) 41 S.W.(2d) 34.
The letter to tbe land commissioner was, on its face, incomplete as a boundary agreement, and parol testimony was admissible to show such terms as were not contained in- the letter. Tbe parol testimony did not vary tbe terms of tbe letter, but shows that an oral boundary agreement bad-been made which was confirmed by tbe letter and bad been acquiesced in and acknowledged. R. A. Halbert, having purchased with notice of such agreement, is bound thereby. 7 Tex. Jur. 198, $ 56.
Tbe appellants contend that, in order for a boundary agreement to be valid, it must be made by tbe owners of tbe land covered there*165by, and, inasmuch as B. M. Halbert was not tbe owner of certain sections, but beld them under a contract to purchase, subject to approval of title and the probate court, the entire written instrument was void and unenforceable.
It is not contended that the contract to purchase these lands by B. M. Halbert was not consummated and title thereto acquired by him. In fact, it was conceded by all parties in the oral argument that the contract to purchase had been consummated and B.. M. Halbert thereby became the owner of such sections. No rights of third parties having intervened between the date of the contract of purchase and its consummation, this contention is not tenable.
The judgment is affirmed.
