An instruction that a real estate agent is not entitled to recover for his services if he failed to accomplish the sale, and the vendee was induced to reconsider his resolution and purchase by another agent, notwithstanding the vendee might never have looked at the property or thought of buying it but for plaintiff, "as his agency was not the immediate and efficient cause of the sale," was properly refused, where there was no evidence that another agent was instrumental in effecting the sale, and also, because the jury were likely to misunderstand the last clause, and regard it as an independent part of the instruction. Solomon v. Cress, 29 P. 439, 22 Or. 177.
