(After stating the foregoing facts.) Whether or not certain testimony objécted to was, as contended by the petitioner, an attempt to vary the terms of the deeds, is immaterial, since it did not in fact authorize any finding that the petitioner’s boundaries were otherwise than as stаted in his deed. This is true for the reason that, with reference to Dr. Fleming’s hedge from which the defеndant’s witnesses testified that they measured 75 feet south to what the defendant contends is his southern boundary, there is no testimony that the hedge did in fact coincide with such southern boundary of Dr. Fleming; and, of course, if the hedge was not on the correct boundary line, it would not furnish a starting point from which the defendant could measure off the 75 feet that he was entitled to under his dеed.
The defendant did not offer any evidence to contradict the positive testimony of the surveyor that the disputed area was not covered by the defendant’s deed, but, оn the contrary, was included in the petitioner’s deed. However, the defendant insists that the evidence shows that the disputed line was established by a subsequent agreement between him аnd the common grantor.
An unascertained or disputed boundary line between coterminоus proprietors may be established by oral agreement, if the agreement be aсcompanied by actual possession to the agreed line, or is otherwise duly exеcuted.
Williams
v.
Prather,

Ga.
545 (1) (
In the present case, the dispute arose between the petitioner *224 and the defendant after the common grantor had disposed of the entire tract, and had therefore ceased to be a coterminous landowner.
The common grantоr testified as a witness for the defendant that he pointed out the dividing line after the dispute аrose. While the defendant testified that after purchasing the land and being placed in possession the common grantor pointed out the dividing line, still, he did not testify that this line was pointed out during the two-year period in which the common grantor retained title to the adjoining land, subsequently conveyed to the petitioner.
“The testimony of a party who offers himself аs a witness in his own behalf is to be construed most strongly against him, when it is self-contradictory, vague, or equivocal.”

The defendant’s son, who purchased the land for his father, testified that the dividing line was pointed out to him during negоtiations for such purchase.
“Where parties reduce their agreement to writing, all oral negotiations antecedent thereto are merged in the writing, and even though the writing dоes not express the contract actually made, the parties must stand by it until it is reformed in a proper way by a competent tribunal.”

It follows that the evidence demandеd a finding in favor of the petitioner, and the trial court erred in rendering a judgment finding the locаtion of the boundary line as claimed by the defendant, and in denying an injunction as sought by the pеtitioner.
In this view, it is unnecessary to decide whether merely pointing out what is supposed by all concerned to be an established line is sufficient to constitute the establishment by pаrol of an “unascertained” boundary line between coterminous proprietors. See, in this connection, Commissioner of Internal Revenue v. Owens, 78 Fed. 2d, 768, where it is said that the word “unascertained” is defined as meaning not certainly known or determined.
Judgment reversed.
