David Josiah Brewer,
Larkin v. Upton — Opinion of the Court
“ The apex of a vein is not necessarily a point, but often a line of great length. Any portion of the apex on the course or strike of the vein found within the limits of a claim is sufficient discovery to entitle the locator to obtain title; for, while the owner of a vein may follow it in its descent into another's territory beyond his own side lines, he cannot beyond his end lines, and the vein beyond those end lines is subject to further discovery and appropriation. ”
