Where a corner, supposed to have been established by the government in the surveys of public lands has been acquiesced by adjoining owners of such lands for nearly 20 years, and improvements made, and the land broken up to the line thus established, there is a presumption in favor of such corner being the true one, which can only be overcome by clear and convincing proof that it was not established by the government. Coy v. Miller, 31 Neb. 348, 47 N.W. 1046 (1891). See also Neb. Rev. Statutes §23-1908.
Monuments of original government survey, if found, control location of section corners. Runkle v. Welty, 86 Neb. 680, 126 N.W. 139 (1910).
