Land Grants and Land Patents are Contracts for Conveyance of Land Titles.
The highest title to land in the United States is a Government grant, a patent
either from the National Government or a State. A Government grant for land has
been, and is held to be, "a contract executed." (Fletcher v. Peck, 6 Cranch, 87.)
