US SUPREME COURT DECISIONS

1. The Act of Sept. 28, 1850, 9 Stat. 519, granting swamp lands, makes it the duty of the Secretary of the Interior to identify them, make lists thereof, and cause patents to be issued therefor. Held that a patent so issued cannot be impeached in an action at law by showing that the land which it conveys was not in fact swamp and overflowed land.

2. Railroad Company v. Smith, 9 Wall. 95, examined, and held not to conflict with this principle.
