In an action by a broker against the president of a corporation, who employed plaintiff without authority, for furnishing one ready, able and willing to purchase land from the corporation, it was no defense that the contract or agreement which was entered into between the prospective purchaser and the defendant was unilateral, and that the prospective purchaser might have declined to perform, where it was clearly shown that the prospective purchaser was anxious to perform, and would have done so except for the refusal of the corporation to approve the contract or to convey.
