In an action to recover real estate brokers' commissions, the plaintiffs' right to go to the jury depended upon whether their evidence tended to show that they procured a purchaser ready, able and willing to buy their principal's land, at a price and upon terms which they were authorized to make, and there being no evidence that they were authorized to agree to pay the purchaser $50 a day as liquidated damages for a breach of the contract to convey, and to secure the same by a lien on the land, or that the proposed purchaser would have taken the lands without such agreement, a verdict was properly directed for defendant. Evarts v. Fuqua (Tex. Civ. App. '08), 111 S. W. 675; affirmed 118 S. W. 132.
