Though a broker's contract of employment provided that he should not receive commissions unless the deal was closed, and that the commissions were payable from the proceeds of the sale, the broker, in the absence of a contract to that effect, was not required to see that the purchase price was paid before he could receive commissions, as the duty to collect the price devolved on the seller, and not on the broker. Pinkerton v. Hudson (Ark. Sup. '08), 113 S. W. 35.
