Opinion by

The defendants plant their defense on an inference which they draw from their contract with the plaintiff. They undertake to distinguish this contract from others relating to the payment of the price of chattels where no time is fixed for such payment because of the provision in the agreement that the plaintiff would “carry the above bonds” at the rate of six per cent interest. The effect of this is said to be to create a liability on the part of the vendor to carry the loan indefinitely at the option of the defendants. It would appear from the terms of the agreement that it was understood between the parties that the price of the bonds was to be charged against the defendants and the bonds held by the plaintiff as security for the payment of the debt. It would seem, also, that the transaction implied further negotiation as to the time during which the loan was to be carried or that the parties had in view a custom between brokers not disclosed in the contract or the affidavit of defense. It would follow as a legal consequence of the extension of credit to the defendants that they became liable to pay interest for the time the indebtedness existed, and the rate of interest named is only that which the law would fix in the absence of any agreement of the parties. It is a rule which the appellants do not controvert that where no time is specified in a note or *244other obligation for the payment of money the parties are presumed to have intended that the money should be payable immediately: Demarest v. McKee, 2 Grant, 248; Rhoads v. Reed, 89 Pa. 436; Bank of Columbia v. Hagner, 26 U. S. 455. When the sale was completed and the defendants were charged on the plaintiff’s books with the purchase price of the bonds the title to the latter vested in the defendants, subject to the payment of the purchase money, and the obligation to pay on demand arose. This presumption is not overcome by the provision for the payment of interest. An agreement to lend money without a period fixed at which repayment is to be made is not an agreement for a perpetual loan although the parties may have stipulated that while the indebtedness existed interest should be paid. To hold that this contract was an agreement on the part of the plaintiff that he would never call for the payment of the debt as long as the interest was paid is to attach to it a condition not expressed in the letters passed between the parties, nor inserted into the contract by legal implication. A provision so unusual in a contract should be clearly set forth. The authorities cited by the appellants do not sustain their position. In Singerly v. Thayer, 108 Pa. 291, it was expressly agreed that the machinery installed by the plaintiff was warranted satisfactory in every respect, and the court very properly held that where there was an agreement to furnish an article to the satisfaction of the purchaser it was not a compliance with the contract to prove that he ought to have been satisfied. Nelson v. Von Bonnhorst, 29 Pa. 352, was a case in which the plaintiffs sued on a sealed instrument in which the defendant bound himself to pay “whenever in my opinion my circumstances will enable me to do so.” Such an obligation created no legal duty enforceable at law because it was agreed that the debtor should be judge of the time when he was able to pay. The defendant was relieved by the very terms of the contract. The view of the contract under consideration most favorable to the appellants is that it provided for the postponement of the payment for the bonds for a reasonable length of time and this, the plaintiff alleges in the declaration, was allowed. It was not until after the lapse of fourteen *245months from the purchase by the defendants that the plaintiff's assignees sold the securities and applied the proceeds on the debt. This was done after demand for payment and after notice to the defendants that the bonds would be so sold at a date named unless they were redeemed in the meantime. There is no denial in the affidavit of defense that the time allowed the defendants was not a reasonable time and there is nothing in the transaction from which it might be inferred that such was the case. There is no question of fact raised by the pleadings, therefore, on which an appeal could be made tó a jury. What is a reasonable time for the performance of a contract is ordinarily a question of fact for a jury where a dispute is raised on that question. But as that controversy is not raised here by the affidavit of defense the case cannot be disposed of as if there were such an issue.

We think the case was properly decided and the judgment is affirmed.
