In an action by a broker to recover commissions on a sale of realty, the evidence showed that defendant agreed to pay $20,000 commissions on the sale of certain coal lands, and that plaintiff secured a purchaser, and that the land was sold and the consideration received in corporate stock. Defendant agreed that on the sale of the stock he would pay one-fourth of the proceeds of every sale made by him until the $20,000 was paid; after several sales defendant sold for a reduced sum the balance of the stock which he had received, having paid plaintiff his proportion of previous sales. Held, that plaintiff was entitled to recover out of the sum paid for the balance whatever was due him of the $20,000. Ryan v. Starr, 214 Pa. St. 318, 63 A. 704.
