They are not in conflict with that which is written. Under these circumstances they must be deemed to be a part of the order and cannot be eliminated therefrom by the court upon an inference as to the intention of the parties which is not reflected in the order or in any evidence that was received upon the trial. The clause requiring a prompt acknowledgment by the plaintiffs of the defendant’s offer as a condition to its acceptance was not in conflict with any of the provisions expressed in that offer either written or printed and must, therefore, be given effect. When the defendant’s letter of April 6th is so considered it becomes evident that it did not constitute an acceptance of the offer of the plaintiffs, but was a new proposition for a contract upon the terms therein proposed. The letter of January 7th by the defendant in which it declares that Rogers acted without authority refers to the “transaction in April last relating to 12 tons of crude rubber.” This statement obviously refers to the matters set forth in the letters of April 4th and 6th, and if these letters do not, when read together, constitute a contract it is evident that when read in connection with the defendant’s letter of January 7th they fail to express a contract. There was no contract because, as has been shown, the plaintiffs did not accept the counter offer of the defendant expressed in its letter of April 6th.
