the Company within 30 days from its date, and shall not be binding upon the Company until so accepted and returned, and approved in writing by an executive officer of the Company.”
As heretofore noted, the Proposal of February 4, 1949, was signed by C. J. Schutty in behalf of the defendant, and the Proposal of June 9, 1950, was signed by A. W. Leighton in behalf of the defendant. It is not the claim of the plaintiffs that C. J. Schutty and A. W. Leighton were not executive officers of the defendant. It is the claim of the plaintiffs that there is no showing of acceptance within 30 days or any acceptance of either proposal.
Section 554.3, Code of Iowa 1954, I.C.A. (Uniform Sales Act), provides, in part, as follows:
“ * a contract to sell or a sale may be made in writing (either with or without seal), or by word of mouth, or partly in writing and partly by word of mouth, or may be inferred from the conduct of the parties.”
In 17 C.J.S., Contracts, § 34, page 362, it is stated: “Every agreement, whether written or oral, is the result of, and springs from, an offer and the acceptance thereof.” In 17 C.J.S., Contracts, § 36, page 363, it is stated: “An offer is the signification by one person to another of his willingness to enter into a contract with him on the terms specified in the offer, *.” A party who signs a proposed agreement and tenders such signed instrument to a party with whom he proposes to contract thereby makes an offer to such party in accord with the terms specified therein. Cohen v. New England Mut. Life Ins. Co., 7 Cir., 1944, 140 F.2d 1, 2, certiorari denied, 1944, 322 U.S. 744, 64 S.Ct. 1153, 88 L.Ed. 1576. The defendant by signing the Proposals of February 4, 1947, and June 9, 1950, and tendering them to the Iowa Public Service Company, thereby made an offer to the Iowa Public Service Company upon the terms specified therein. However, the document containing the offer also contained a provision relating to the acceptance thereof. That provision provided that such offer must be accepted by the Iowa Public Service Company within 30 days from the date of the contract. On March 9, 1949, the Iowa Public Service Company executed the written “Purchase Order” dated March 9, 1949, and mailed it to the defendant. That instrument clearly and definitely related to the offer of the defendant dated February 4,1949, and constituted a purported acceptance thereof. However, it was a belated acceptance. Section 73 of the Restatement of The Law of Contracts and Comment is as follows:
“An offeror who receives an acceptance which is too late or which is otherwise defective, cannot at his election regard it as valid. The late or defective acceptance is a counteroffer which must in turn be accepted by the original offeror in order to create a contract.
“a. How such a counter-offer as is referred to in the last sentence of the Section may be accepted depends on the general principles which govern acceptance. . ”
In the Iowa Annotations to that Section of the Restatement (p. 53), it is stated:
“Ferrier v. Storer, 1884, 63 Iowa 484, 19 N.W. 288 (late acceptance of offer to borrow money), is in accord with the proposition that the offeror cannot at his election regard a defective acceptance as effective. This case would seem by inference to support the proposition stated in the section that a late acceptance may operate as a counter-proposal.”
See also Wax v. Northwest Seed Co., 1937, 189 Wash. 212, 64 P.2d 513, 515. However, as heretofore noted, because of an error in the original set of specifications which was carried through into the “Purchase Order” dated March 9, 1949, new specifications were prepared
