Opinion op the Court. —This action of debt is founded on a contract in writing, under a penalty of twenty thousand dollars, conditioned to perform certain articles of agreement entered into at the same time, namely, the 8th of December, 1837, between Lorenzo N. Clarke and the government, to furnish rations to the Chickasaw Indians. The penal bond, with the conditions thereunder writtén, and the articles of agreement, constitute but one agreement, upon which the United States have brought their action.
The defence disclosed by the defendants, — seventh, eighth, and ninth pleas, to which the district attorney has demurred, — is a subsequent agreement by the defendant Clarke with the plaintiffs, obligating himself to deliver to the United States rations of beef, corn, and salt, at a specified price, for all the Seminole Indians who should emigrate west during one year after the date of the contract, and stipulating that he should be entitled to a credit of five and a half cents for every ration of subsistence so delivered upon his indebtedness under the contract upon which the present suit is based.
The defendants fail to aver in their pleas that any rations were in fact delivered under the latter contract; but they do allege that this latter agreement was received by the plaintiffs in full satisfaction and discharge of the covenants and stipulations contained in the contract referred to in the declaration.
By adverting to the terms and provisions of the latter, it appears manifest that it was not the intention of the parties that it should operate by way of discharge and satisfaction of the obligations incurred by the first agreement, for it provides expressly that for each and every ration delivered by Clarke, he should be entitled to a credit of five and a half cents on the first contract, so that he might liquidate and pay his debt due to the plaintiffs under the same.
The contract set out in the pleas affords intrinsic evidence not to be mistaken, that the parties to it never intended it as a discharge and satisfaction of the previous contract, but, on the contrary, they manifestly intended that the first contract should *317remain in full force, and only provided that' it might be satisfied, paid, and discharged by the delivery of a sufficient number of rations of subsistence. When delivered, they should operate to liquidate and discharge it. That was the object, and nothing beyond it.
The averment in the pleas, that the latter contract was received by the plaintiffs in full discharge and satisfaction of the former contract, cannot be regarded, because it is inconsistent with the terms and provisions of the contract itself, as well as the clear intention of the parties.
It may be further remarked, that the amount of rations to be furnished by the defendant Clarke is left wholly uncertain and entirely dependent upon the number of Seminole Indians that might emigrate during the year. It rested on that contingency.
It seems to me that it can admit of no serious doubtj that a contract thus uncertain an dun performed in any part, cannot be legally pleaded as an accord and satisfaction of a previous liability. 1 Com. Dig., Accord (b. 3), 201. The pleas are not sufficient in law to bar the action, and the demurrer to them must be sustained. Demurrer sustained.
The seventh and eighth pleas having been amended by leave of the court, the district attorney again demurred, for this, among other causes, that “ the pleas did not show that the accord had been executed, without which it could not be a bar to the action.”
Opinion ok the Court. — This action is in substance for the recovery of damages for a breach of covenant, and is governed by the rules applicable to that action.
To an action of covenant, the defendant may set up various defences in bar of the action. He may deny that he ever made the covenant, by putting in the plea of non est factum; or he may plead a fraud practised upon him in its execution, and so avoid it. He may plead that he has performed the covenant stipulated on his part to be performed, or that he is discharged from performance by the failure of the plaintiff to perform a condition precedent. He may plead an accord, which Black*318stone defines to be “a satisfaction agreed upon between the party injuring and the party injured, which, when performed, is a bar to all actions upon this account.” 3 Bl. Com. 15; 1 Bac. Abr. Accord, 54.
The question arises in this case, To which of these classes of pleas do the seventh and eighth amended pleas belong? Are they pleas of accord and satisfaction, or of covenants performed ? It seems to me that they are not pleas of the latter class, because they fail to aver performance. It is true that they aver part performance, and a readiness and an offer to. perform fully, which was refused by the plaintiffs. The defence then is, part performance and a legal excuse assigned for failure to perform fully.
A part performance, and a readiness and offer to perform the residue, is not in all cases equivalent to an actual, full, and complete performance. For example; if A. covenants with B. to do any specific act, as to deliver certain property upon the demand of A. at a certain place, and B. is sued by A. for a failure to deliver the property, B. may show that he could not deliver it, because A. never made the demand, and so bar the recovery of damages, on the ground that he was prevented from performing the contract by the fault of A., and not by any fault of his own.
But suppose the action should be brought by B., can he recover the same amount of A. that he would be entitled to, in case he had actually delivered the property and fully performed his contract? Clearly he could not. He could recover no more than the damages he had sustained by reason of the failure of A. to make the demand, so as to enable B. to comply with his contract. B. never having in fact delivered the property, would not be entitled to recover its value. The property is still his own, and he could only legally recover of A. the damages occasioned by the breach of the contract on the part of A. Thus it appears that part performance and readiness to perform in full does not give a party the same rights.
These, then, are not pleas of covenants performed. To what class do they belong ? It appears to me .that they can only be considered as pleas of accord, and arc they, in the form *319pleaded, valid ? I think not; for it is not averred that the accord was received and accepted in satisfaction of the contract sued on ; but it is averred that performance of the new agreement was to operate as satisfaction. Full performance, as already remarked, is not alleged; and according to the best authorities, an executory agreement- unperformed cannot be set up as a valid accord and satisfaction. 1 Bac. Abr. Accord and Satisfaction, A. 55; 1 Ld. Raym. 122; 6 Wend. 390; 16 Johns. 86; 2 H. Bl. Rep. 317; 5 T. R. 141.
The demurrer to the seventh and eighth amended pleas is sustained. Demurrer sustained,,1
