The defendant in error, plaintiff in the court below, instituted suit against the plaintiff in error, defendant there, for damages growing out of the alleged breach of two contracts for the purchase and sale of coal. Under these contracts the plaintiff in error was the seller, and defendant in error, the purchaser. After issue was joined, the ease was tried to the court without the intervention of a jury, and the trial court found for the plaintiff, the purchaser, and assessed its damages in excess of $19,000, including interest, to which findings and judgment exceptions were taken and the case brought here upon proceedings1 in error.
It will not be necessary to discuss the pleadings, as an outline of the facts will disclose the legal propositions involved.
The seller received two oral orders for *527100 ears of coal each, from the purchaser, and accepted the orders by two written acceptances almost identical in form; the one calling for lump coal and the other for egg coal.
The legal questions involved very largely grow out of the interpretation of these contracts, and as they are practically identical except as to the kind of coal specified, one only of them will be used for consideration here, being in form as follows:

“Boehmer Coal Company,
“By Will H. Boehmer, Pres. M.”
The subsequent facts material to the discussion of the issues appear to be that the contracts were turned over to the Edwards-ville Coal Company by the Boehmer Company, for fulfillment of the orders. Under the lump coal contract, some 30 cars were shipped, but none under the egg coal contract.
The difficulty between the parties appears to have arisen out of the refusal of the Wabash Railroad, designated by the contracts as the carrier for the delivery of the coal, to furnish further cars; that railroad taking the position that inasmuch as the coal was for the use and benefit of the Pennsylvania Railroad, cars of that system should be furnished for the fulfillment of the contracts. Demands were made upon the local agent of the Wabash Railroad at intervals for cars to make the shipments called for by the contracts, by the Edwardsville Coal Company, and subsequently the Boehmer Company advised the Burton Company of the difficulty arising in securing cars and made demand upon the Burton Company to secure the necessary cars. The Burton Company evidently took the position that it was the duty of the Boehmer Company to provide cars, but in any event no further cars of coal were shipped under the contracts.
During the negotiations between the parties, the Burton Company, the purchaser, proposed to have the remaining shipments diverted to other points and other consignees for the purpose of assisting the Boehmer Company in fulfilling its contract; but the Boehmer Company refused to accede to this arrangement, and in course of time this lawsuit originated.
*528The first point for consideration is the contention of the plaintiff in error that the contracts are void for lack of mutuality. This contention arises out of that clause in the contracts which reads as follows: “This order is not subject to cancellation after shipment has been made.” Counsel for plaintiff in error contend that the proper interpretation of the contracts.in the light of this clause is that any portion of the order not shipped was subject to cancellation by the purchaser, thereby becoming unenforceable and void for want of mutuality.
While it is undoubtedly true that courts will strive to give meaning to each constituent part of a contract, it is likewise true that the courts will strive to give that construction which will make a contract valid and binding instead of a construction making it void or unenforceable. 13 C. J. 539; American Sugar Refining Co. v. Newnan Grocery Co. (C. C. A.) 284 F. 835; Hobbs v. McLean, 117 U. S. 567, 6 S. Ct. 870, 29 L. Ed. 940, and the authorities there cited.
It is also .to be assumed that parties entering mto a contract intend to make, it binding ’and enforceable. American Sugar Refining Co. v. Newnan Grocery Co., supra. It is therefore clearly the duty of the court to make an honest attempt to sustain the validity, of. the contracts under this, well-recognized rule of law, and particularly in view of .the facts in this case, that the parties undoubtedly considered themselves bound, at least until controversies arose, with the additional persuading circumstance here that - the contracts had become partially. executed.
As to the interpretation of the above-quoted clause, in order to sustain the contention of .plaintiff in error it would be necessary to 'construe 'the contracts as affirmatively asserting that they were subject to cancellation before shipment. It appears that this would be. a forced and strained construction in the light of the circumstances surrounding these contracts and the action of the parties in carrying them into effect, because it would be reading into the contracts a. provision in the first instance which is clearly not there, and in the second place it would mean a construction which would .render the contract void and unenforceable in violation of the rule of construction by the courts.
It may either be said that this is a vague and ambiguous clause which can easily be disregarded as in no way affecting the clearly expressed binding obligations of the parties to the contracts (13 C. J. 535), or, as frequently occurs in contracts, it may be regarded as the mere statement- of a rule of law, the principle of which would govern the rights of the parties whether inserted in the contract or not. The trial court took the view that it might fairly be regarded as the statement of a legal truism. This principle is supported by authority. Hogue-Kellogg Co. v. Baker, 47 Cal. App. 247, 190 P. 493; Mayo v. American Malting Co., 211 F. 945, 128 C. C. A. 443. Furthermore, the contracts were upon regular printed forms of the Boehmer Company and should therefore be construed most strongly against it. Mt. Vernon Refrigerating Co. v. Wolf Co., 188 F. 164, 110 C. C. A. 200.
It having been determined that the contracts in this case are valid and enforceable, the point as to why they were not carried out remains to be considered. One of the defenses of the Boehmer Company was that it was unable to secure equipment for shipping the coal although making every effort to secure such equipment and that it had called upon the purchaser, the Burton Company, to furnish such equipment which it had neglected and refused to do. The evidence shows that the Boehmer Company first assumed the duty of furnishing equipment to the extent at least that it made requisition and demand upon the local agent of the Wabash for cars through the Edwardsville Coal Company, the Boehmer Company’s agent,' but excepting this simple effort there is no evidence that the Boehmer Company pursued the matter further but apparently relied upon its demand upon the Burton Company to supply the cars. If it were the duty of the Boehmer Company, as the seller, to furnish cars, it is-very clear that it fell far short of exercising reasonable diligence in discharging that duty. It therefore becomes pertinent here and one of the decisive features of the case to determine upon which party rested the-legal duty of furnishing the equipment.
The contracts contain this provision:. “Orders accepted subject to our ability to get the proper equipment to go the route.” Here the Boehmer Company has by a self-prepared contract assumed the obligation of providing the equipment. It is incumbent, upon the party on whom the responsibility rests to make every reasonable effort to carry out the terms of the contract. 35 Cyc., 247; Jessup & Moore Paper Co. v. Piper (C. C.) 133 F. 108; Consolidation Coal Co. v. Peninsular Portland C. Co. (C. C. A.) 272 F. 625.
Another cogent reason for holding-that it was the duty of the Boehmer Com*529pany to supply the ears is the fact that the place of performance of the contracts was the Edwardsville mines, in the state of Illinois. The courts of that state have determined that under contracts similar to those in the ease at bar, particularly whore it becomes apparent that such a construction has been placed upon the contracts by the parties themselves, it is the duty of the seller to furnish the cars. Consolidated Coal Co. v. Schneider, 163 Ill. 393, 45 N. E. 126; Harman v. Washington Fuel Co., 228 Ill. 298, 81 N. E. 1017; Consolidated Coal Co. v. Jones & Adams Mnfg. Co., 232 Ill. 326, 83 N. E. 851.
The evidence in the case shows that when the difficulty in securing cars for shipment to the Pennsylvania System became apparent, the Burton Company offered to change the destination and consignee as set forth in the contracts for the purpose of securing their fulfillment, to which suggestion the Boehmer Company failed to respond. In this respect the Boehmer Company maintains that the routing and destination were material parts of the agreement and not subject to change at the will of either party. Under the circumstances in this ease, such a contention of the Boehmer Company cannot bo sustained. The contracts fix the price of the coal f. o. b. the mine, which was at Edwardsville, Ill. The expense, as well as the risk of the transportation to the point of delivery, therefore rested upon the Burton Company, and it would seem to make no difference to the Boehmer Company as to the destination of the shipment. Such a provision in the contract is little more than a direction to the seller, or at best is purely for the benefit of the purchaser and may be waived by him without disturbing or affecting any of tho rights of the seller under the contracts. The determining point upon such a question is whether or not such a change in destination of the shipment would impose additional expense, undue delay, or additional burden upon tho seller, and if it be determined that it would not, the stipulation in the contract should be held to he for the benefit of the purchaser, which he could waive at will without releasing the seller from Ms obligations. Meyer v. Sullivan, 40 Cal. App. 723, 181 P. 847; Douglas Fir Exploitation & Export Co. v. Comyn (C. C. A.) 279 F. 203; Matthew Smith T. C. & G. Co. v. Lamborn Co. (D. C.) 276 F. 325.
Under the circumstances in the ease at bar, it is manifest that the change in point of destination and consignee would have added nothing to the burden of the Boehmer Company under the contracts. The fact that after the contracts were entered into there was a sharp rise in the price of coal is in tliis connection significant of what might have been the true reason why the contracts were not carried out.
The only remaining point in the ease is that raised by the Burton Company that the Boehmer Company was estopped from assorting tho invalidity of the contracts in court for the reason that up until the time suit was brought the only contention of the Boehmer Company in regard to its failure to fulfill the contracts was either its inability to secure ears or the failure of the Burton Company to furnish them, and that the Boehmer Company could not after having taken one position, when afterward brought into court, assert another and different reason for not having fulfilled its contracts, but should be hold by its conduct to have waived other claims. The general rule upon this question laid down by the courts finds its best expression in the case of Railway Co. v. McCarthy, 96 U. S. 258, whore the court at page 267 (24 L. Ed. 693), says:
“Where a party gives a reason for Ms conduct and decision touching anything involved in a controversy, he cannot, after litigation has begun, change Ms ground, and put his conduct upon another and a different consideration. He is not permitted thus to mend Ms hold. He is estopped from doing it by a settled principle of law.”
It is earnestly urged, however, in behalf of the Boehmer Company, that this rule does not apply in a ease where a subsequent contention of tho party, when sued, challenges the validity of the contract itself, and that the rule is that such a contention may be asserted at any time without respect to what the former claims of tho litigant might have been.
This contention seems to find support in tho case of Interstate Iron & S. Co. v. Northwestern Bridge Co. (C. C. A.) 278 F. 50. On the other hand, the contention of the Burton Company, that there is an estoppel even whore the subsequent claim relates to the validity of the contract, is at least asserted as a principle of law in the following eases: Luckenhach Co. v. Grace (C. C. A.) 267 F. 676, and Grimwood v. Steamship Line (C. C. A.) 273 F. 166.
In the very recent case of Second National Bank of Allegheny v. Sash Corporation (C. C. A.) 299 F. 371, decided by the Circuit Court of Appeals for the Third Circuit, it is asserted that the rule announced in the McCarthy Case, supra, is based *530upon the principle of equitable estoppel an4 that the facts of each case must be examined to ascertain whether or not the rule should be applied. If it be found that the party asserting the new contention has not by and on account of his original claim “misled his adversary or induced him to alter his position to his prejudice,” and where the facts themselves do not raise an estoppel, then the rule should not be applied.
In the view which the court has taken, that the contracts were valid and binding in the case at bar and that the failure to fulfill them rested upon the Boehmer Company, it appears that this is a point, the determination of which is not necessary to a decision of the case, but it has been deemed advisable to bring the authorities together in discussing all the legal questions presented. In addition to this, it appears that the defense of estoppel was not pleaded by the Burton Company in its reply, and it is therefore problematical whether or not the question is squarely before the court.
The judgment of the trial court will be and is affirmed.
