George Sutherland, Son v. United States — Opinion of the Court
“ If the appropriation of mineral lands by location and development be not skin to settlement and entry, what other form of appropriation can be so characterized? None has been suggested and we can think of none. A purchase of land or an appropriation for railroad uses or rights of way, if not actually involving settlement and entry, is no more akin to that method than an appropriation for mining purposes. ”
