If the subject-matter of the contract is indivisible, the contract must necessarily be entire.1 A contract to dredge a channel to a certain depth and to dredge the harbor to a different depth is an entire contract in spite of the fact that different depths are provided for, since such covenants are intended to result in an entire improvement and each of them is essential to the other.2

On the other hand, the fact that the subject-matter is divisible is not conclusive of the character of the contract; for the subject-matter may be divisible, but the contract itself may be entire.3 A covenant to locate and operate a sawmill on another's land, such other person to furnish timber, and such contract not to be assignable by either, is entire so that a breach of a substantial part of such contract, such as the covenant against assignment, operates as a discharge of the whole contract.4 A contract to furnish different quantities of different articles is not rendered a severable contract as to performance by the fact that different kinds of articles are provided for.5
