On March 26th, appellee wrote to appellants as follows, using their customary letter-head:
“ March 26,1889.
Summers Bros. & Co., Struthers, Ohio.
Dear Sirs: We notice that some of the iron we are receiving from you is not branded with your name. Hereafter please see that each bundle is branded. It would suit *386us very much better if, in banding the iron, you would put the two end bands from twelve to fifteen inches from the end of the sheets, instead of about six inches, as you now place them. We find that when the bands are put on as suggested above, the iron can be piled in very much better shape. We are thinking some of placing another order for common iron for shipment in July and August, and would be pleased to have you give us your best figures.
Tours very truly,
Hibbabd, Spencer, Bartlett & Co.”
On March 28th appellant replied with the following letter, on a plain piece of paper with no letter-head:
Struthees, Ohio, Mar. 28, 1889. Hibbard, Spencer, B. & Co., Chicago, 111.
Gentlemen : Tour favor of 26th received. We will band the iron as you suggest, and have notified shipper that, every bundle must have our brand on. We will furnish you 3,000 to 5,000 bundles, June, July, August and September delivery.

To this offer appellees on April 3rd, replied:
“ April 3rd, 1889.
Tour favor of-the 28th ult. is at hand. We would not care to enter an order at the advance which you ask. If you care-to make an addition to our former order for July,August and September delivery, we will decide whether we want 3,000 or 5,000 bundles, and send you contract to that effect. We would not, however, as we said before, care to enter at the price you now name.”
Appellants on April 5th replied, using the same letterhead as in the letter of March 11th :
*387“ April 5, 1889..
Your favor of April 3d at hand. We will enter your order 3,000 or 5,000 bundles July, August and September delivery, at same figures as former order. We owe yoT 310 bundles April. Will you want all Ho. 26 and 27?
Summers Bros. & Co.”
Appellee subsequently consented to receive 3,000 bundles under this second contract, but appellants never delivered any under it, and delivered but 1,847 bundles under the first contract. As an excuse for not doing so, they claimed to appellee on July 24th, that the contracts were made subject to strikes and accidents, and that they were prevented from filling the contracts in time, by reason of breakages in their mills.
A Mr. Charles acted as the agent of appellees in making the contract of sale. Upon the trial, one of the appellants was permitted to testify what Mr. Charles told him some months after the contract was made, he, Charles, at the making of the contract, knew and understood as to. the printed statement on appellant’s letter-heads—“all sales subject to strikes and accidents”—forming a part of the contract.
Charles denied having made the statements attributed to him.
Appellees, in August, 1889, bought of other parties the iron contracted for, which appellants failed to supply, and proved by uncontroverted evidence that the purchase price at the time of such purchase remained the same from then through the month of September and into October.
Appellees sued for the difference, that is, for the amount paid by them in excess of the contract price. If appellees were entitled to this, it was undisputed that there was due them the sum of $1,546.61, and for this amount the court instructed the jury to find for the plaintiff.
Counsel for appellants state the controversy to be:
First. The appellee contends that it is entitled to the payment made to it for iron in excess of the contract price, and that it is not bound by any printed condition contained *388in the letters on which the contract is based. The appellants insist that when the offer of sale was' made on March 4th, it was on the express condition, subject to “ strikes and accidents,” and that the failure on their part to deliver was by reason of accidents in their mill plant. And therefore they should not be charged as claimed by the appellee.
Second. That appellee seeks to recover an-amount based upon the excess paid by it for iron bought in the month of August, 1889, without offering to prove what the market price of iron was, at the date when each installment was to be delivered.
While we do not think this a completely accurate statement, yet it sufficiently indicates the nature of the controversy.
We do not regard the line “All sales subject to strikes and accidents ” at the • top of certain letters written by appellants as any part of the contract of sale by them made. The first co^raét was made by the letter of March 9,1889, written by appellee to appellants, in which was a definite proposition for the unconditional purchase of a certain quantity of iron, and by the reply of appellants to this. This reply, dated March 11th, accepted the offer of appellee.
It is contended that this letter written by appellants, beginning with “We accept your offer,” following wíiich is a repetition of the terms of the offer made by appellee, was a merely conditional acceptance and made a merely conditional sale, because there was printed thereon, not in the body of the letter or in the words stating the acceptance or promise, but above the address, the sentence, “All sales subject to strikes and accidents.” It is to be borne in mind that this sentence is a part of a printed letter-head, while the words of acceptance were written for the time and occasion; that the letter of acceptance was entirely the production of appellants and such as they saw fit to give; that if they intended to make only a conditional acceptance, it was easy for them to have written, not, “ we accept your offer,” but words that would have clearly indicated a conditional *389acceptance only, and thus have left the negotiations at that point incomplete and fruitless.
The rule of law that a man’s own acts shall be taken most strongly against himself, obtains not only in grants, but extends in principle to all other engagements and undertakings. Gibson et al. v. Minet et al., 1 H. Blackstone 569-586; Broom’s Legal Maxims, 596.
The conduct of appellants subsequent to the writing of this letter indicates that they did not regard their acceptance as conditional. The offer of appellees was absolute ; a conditional acceptance would have made no contract, but appellants, without asking an assent to any conditions they now insist existed, proceeded to forward iron to appellee.
If the words “ All sales subject to strikes and accidents ” were to be considered a part of the contract, the question of their effect would arise.
The sale was of iron, a quantity of “ common sheet iron,” not necessarily of appellants’ manufactúre. Were, then, the strikes and accidents alluded to, those only occurring in appellants’ mills ? And if so, what would be their effect upon the contract ? That is, would such strikes and accidents put an end to the contract and absolve the vendors from any further liability, or would they merely suspend the operation of the agreement and extend the time of delivery to a period when the strike was over or the damage resulting from the accident had been repaired %
The undertaking of appellants would have been satisfied by a delivery of merchantable, common sheet iron, the product of mills neither owned nor controlled by them; that the printed head-line, “ All sales subject to strikes and accidents ” entered into and formed a part of such a contract, we see no reason for thinking.
Having a right to supply merchantable bar iron made in any mill, the accident at appellants’ in no wise rendered the performance of the contract impossible.
The testimony of one of appellants as to what Mr. Charles, the agent of appellee, said to him some months after the contract was made, ought not to have been admitted. *390There is no implied authority of an agent to, after the doing of an act, make admissions for his principal concerning the same.
The statements of an agent are admissible, generally, only when they are part of the res gestee. Story on Agency, Sec. 134, 137; 1 G-reenleaf on Ev., Sec. 133; Whiteside v. Margarel, 57 Ill. 507; Lindblom v. Ramsey, 75 Ill. 246; Bensley v. Brockway, 27 Ill. App. 410; McCarthy v. Muir, March term, 1893, Ill. App.
It is true that appellee could not, for appellants’ account, buy in August, iron not due until September and October, nor can the August price determine the value of iron deliverable in subsequent months; but it is undisputed that appellants failed to deliver or offer the iron due in either August, September or October, and it was uncontroverted that the price paid in August was the price from thence up to a period in October, beyond the date at which the last installment should have been furnished.
Appellants have therefore had all the advantage of an opportunity to deliver in September and October and been charged only with the price ruling at the respective dates when the iron promised was due.
The judgment of the Superior Court is affirmed.
