A contract whereby defendant agreed to sell plaintiff, or his assigns, certain lands for $150 per acre, plaintiff to plat the land and sell it, and to pay the proceeds to defendant until the latter had received $150 per acre, was a contract for the sale of lands, not a mere brokerage contract which defendant had a right to forfeit by reason of non-performance. Whipple v. Lee, 46 Wash. 266, 89 P. 712.
