Validity of entry

When lands are granted, a description which will identify them is all that is necessary to the validity of the grant. But identity is not all that is necessary to the validity of an entry. The law requires that locations should be made with such certainty, that subsequent purchasers may be enabled to locate the adjacent residuum. All grants are founded on surveys; they recite the surveys, and all that is required in an ejectment is, to prove that the land claimed is that which was surveyed. But more is required in a contest respecting an entry; nothing is more common than for courts to declare an entry void for uncertainty, notwithstanding the clearest proof that the land claimed, and that located, are the same.
