Opinion by

In November, 1912, the First National Bank of Pittsburgh established among its employees, numbering about one hundred twenty, a benefit plan by which three active officers of the bank were named as trustees, to whom each employee could at his option pay six and two-thirds per cent, of his semi-monthly salary. In that event, and in that event only, the bank agreed to add thereto a sum equal to ten per cent, of such salary, making a total sav*228ings fund of sixteen and two-thirds per cent. Practically all of the employees joined in the plan and were called “participants.” The bank at its expense was to provide a bookkeeper. The plan contemplated eight-year cycle periods, but the bank reserved the right to discontinue it on the first day of January of any year after 1914, by giving thirty days’ notice. The plan provided for disposition of the fund belonging to a participant on his quitting the service. In no event could the bank derive profit from the plan and only on a certain contingency was money paid in by it to be returned. The plan com teinplated that the fund should be invested by the trustees and permitted them to subscribe for one thousand shares of the bank’s new stock, at $175 per share, the par value being $100. But such permission was conditioned on the trustees procuring and paying the bank the $175-,-000 in cash for the stock, which stock was to remain in the hands of the trustees until the employee severed his connection with the bank. The directors approved the plan but it was not submitted to the stockholders. From about December 1, 1912, to June 30, 1913, the participants paid the trustees as stipulated; and in each case the bank paid its ten per cent. In fact, as matter of convenience, the bank during that time retained the six and'two-thirds per cent, and paid it direct to the trustees. In March, 1913, Oscar L. Telling, who was president of the bank and also one of said trustees, requested of plaintiff, the Commonwealth Trust Company of Pittsburgh, a loan of sixty thousand dollars. He stated that the request was made on behalf of the bank; also explained the plan and that the money was to purchase stock of the bank, which would be put up as collateral. The officers of the trust company took the matter under advisement for some days.'' Meantime at their request he furnished them a full copy of the plan, including the resolution of the directors relating thereto. During the negotiations Mr. Telling stated to said officers that the bank was baek of- the! loan. • • • " ‘ 1 ........

*229Pending these negotiations the bank made a preliminary agreement of merger with the Second National Bank of Pittsburgh, by which, when completed, the latter purchased the assets and assumed the liabilities of the former and became the First-Second National Bank of Pittsburgh. The president thereof, Mr. W. S. Kuhn, also took up the matter of the loan with the plaintiff and wrote its president a letter expressing his intention of continuing in operation the benefit plan for the employees of the First National Bank. The letter also states that “I am aware that the trustees for the clerks of the First National Bank have applied to your good institution for a loan of $60,000 to be secured by 450 shares of the capital stock of the First National Bank of Pittsburgh, and this application has been made with my knowledge and approval.” Subsequent to the receipt of i Ait letter and upon further consideration the trust com- ;; my accepted the loan and took therefor a collateral ..Me of sixty thousand dollars drawn payable to the order of the trustees, and signed and endorsed by them as each. The collateral consisted of four hundred fifty chares of the stock of the First National Bank of Pittsburgh, which in said note is stated to be of the market value of $67,500. The trust company turned over the sixty thousand dollars by a treasurer’s check payable to the order of the trustees and endorsed by them as such. Before the loan was made plaintiff knew that Mr. Telling was one of the trustees; and the loan was entered and continued on the books of the trust company as a loan to them. The chancellor and court below find that the loan was made to the trustees and not to Mr. Telling as president or agent of the bank. The trustees bought four shares of the stock of the First National Bank SO' deposited as collateral and the remaining four hundred and forty-six shares of Mr. Telling, paying in each case $150 per share. The sixty thousand dollars, with seven thousand five hundred dollars which had accumulated under the plan, paid for the stock. The trustees turned *230the sixty thousand dollar check over to Mr. Telling, who deposited it in his private account in the First National Bank, and later checked it out in payment of his indebtedness to that bank. Mr. Telling’s employment as president of the bank was by contract which gave him the powers usually conferred upon presidents of national banks of like size, and also ample authority to exercise his discretion in the internal administration of the affairs of the bank, with complete control of the subordinate officers and employees of the bank.

On July 7, 1913, the First-Second National Bank was closed by the controller of the currency and remained so until April, 1914. Meantime the First. National Bank went into liquidation and its stock became practically worthless. No formal action was taken to abandon the benefit plan but nothing was paid to the .trustees thereon after the bank was closed. The trustees paid plaintiff three thousand dollars on account of the loan and there is now a balance of $305.55 of trust funds in their hands, for which they have ever been ready to account. The trust company filed its bill in this case to compel the bank to pay the note or to so continue the benefit plan as to raise funds sufficient for that purpose. The chancellor heard the case upon bill, answer, replication and testimony, and found the facts and legal conclusions; and the court, below passed upon the exceptions filed thereto and dismissed the bill. Plaintiff took this appeal.

We have considered each assignment of error but find nothing to justify a reversal of the decree. The loan was made either to the trustees or to the bank, and the finding that it was made to the former accords with the evidence. If so, Mr. Telling’s assertion that he represented the bank, or that it was back of the loan, would not render the bank liable. The president of a national bank has no authority to obligate it as guarantor, surety or endorser: First National Bank of Duncan v. Anderson, 141 Fed. 926, 928; Western National Bank of N. Y. v. *231Armstrong, 152 U. S. 346; Monongahela Nat. Bk. v. Harmony Land Co., 226 Pa. 440; Worthington v. Schuylkill Electric Ry. Co., 195 Pa. 211. In Aldrich v. Chemical National Bank, 176 U. S. 618, the bank was held liable because it received the money.

This was such an exceptional transaction that, even considering it as a loan to the bank, the rule that the president or other executive officer of such institution has implied authority to borrow money on its behalf in the usual course of business would not apply. See Dorsey v. Abrams et al., 85 Pa. 299; First Natl. Bank of Allentown v. Hoch, 89 Pa. 324. Treating it as a loan to the trustees, the bank would not be liable on the parol guarantee of its president, especially as a national bank has no power to become an endorser or guarantor of the debt of another without benefit to itself: National Bank of Brunswick v. Sixth National Bank, 212 Pa. 238. Mr. Telling had no express authority from the bank to negotiate or secure this loan on its account, neither had he any implied authority. It was not a transaction relating to the internal management of the corporation and there is nothing to indicate that it was such as ordinarily appertains to the office of bank president. So he could not obligate the bank for the loan even assuming that he attempted to do so. The court below finds on sufficient evidence that the bank did not receive the proceeds of the loan, so it is not liable on that ground. Telling got the money. True, he used it to pay a note to the bank, but the note was a valid obligation which the bank exchanged for the money and its assets were not increased. Telling got the benefit in the payment of his note.

Notwithstanding a determined effort on behalf of plaintiff, the court below finds that the 446 shares of stock turned over to the trustees by Telling belonged to him and not to the bank. So it is not apparent how the bank received any benefit in a legal sense from this loan. The purchase of the stock from Telling was not a breach *232of trust; for while the trustees were given permission to purchase the stock from the bank they were under no obligation to do so.

It is urged for plaintiff that in any event the bank must continue the benefit plan .until a fund sufficient to pay the loan in question is realized; and that it should do so in exoneration of its trustees. This seems to be a misconception of the situation. The bank could realize no profit out of the benefit plan; the participants were the beneficiaries. The bank’s agreement was to pay to the trustees when and only when the participants paid. It never assumed to compel the participants to pay, or to guarantee that they should do so, or to pay obligations incurred by the trustees. The plan recites that the trustees are to procure the cash to purchase the stock; the bank assumed no such obligation. Plaintiff’s construction of the benefit plan, if correct, would in our opinion render it ultra vires the bank. A national bank has only such powers as are given expressly or by necessary implication. See McCormick v. Market Natl. Bank of Chicago, 165 U. S. 538, 550; California Saving Bank v. Kennedy, 167 U. S. 362; Fowler v. Scully, 72 Pa. 456; Bly v. White Deer Mt. Water Co., 197 Pa. 80, 92; Bank of Barnwell v. Sixth National Bank, 28 Pa. Superior Ct. 413. The implied powers are only such as are reasonably necessary for the main purpose: Logan County Natl. Bank v. Townsend, 139 U. S. 67. Such bank has no power to borrow money, or to guarantee the payment of money borrowed by trustees, for use in the purchase of its stock to be parcelled out among employees as a benefit fund. That a corporation is liable for money received by it on an ultra vires contract cannot assist plaintiff, because the bank did not get the'money. And we agree with the conclusion of the court below “that the creation of a liability to collect from the employees a stipulated percentage and to contemporaneously therewith make a contribution to a fund so that a loan incurred in the *233administration of that fund might be paid, is beyond the power of a bank.”

A national bank cannot purchase its own stock, except to prevent loss upon a debt previously contracted. So, on the theory that the bank and the trustees were one, that part of the plan, providing for the purchase of the new stock by the trustees would be invalid; and the bank having received no benefit from the transaction, could set that up as a defense to the loan which was made for such purpose. It is not necessary now to decide whether a national bank can create a benefit fund for, or share surplus earnings with, employees; for we are satisfied that what plaintiff contends the bank assumed to do here was beyond its power. Plaintiff relies upon Heinz v. National Bank of Commerce, 237 Fed. 942. There, however, the stockholders authorized the bank to appropriate not to exceed one-tenth of the net profits in excess of six per cent, for the purpose of an employee’s pension and profit-sharing fund. And it was held to be within the implied powers of the bank, and that expenditures so made could not be recovered back at the instance of a stockholder. There no indebtedness was created nor any liability imposed upon the bank except to distribute the fractional part of the net surplus as directed by the stockholders, to whom it in reality belonged. The decision there also rests on other grounds, but, assuming its entire accuracy, it is not parallel with the case at bar:

Evidence as to the inability of the trustees to personally pay the note in suit was properly excluded as there was no claim or proof that they were personally liable or had mismanaged the trust. Under such circumstances that question could not affect the liability of the bank. Mr. Telling was acting as president of the bank and it was not material to show that he actually exercised the powers conferred upon him by his contract of employment; nor was it material to prove that for ten years previously the First National Bank had given its employees an annual bonus as additional compensa*234tion under a somewhat similar plan. That would not change the rights of the parties, as this action is based upon the new plan.

The original deposit slips, showing a deposit of the money in Mr. Telling’s private account, were properly proven and competent to corroborate other evidence: Littieri v. Freda, 241 Pa. 21; Donahue v. Connor, 93 Pa. 356; Charles v. Bishoff, 1 Sadler 260; Pallman v. Smith, 135 Pa. 188.

There is nothing in the other rulings on questions of evidence that seems to require comment.

The assignments of error are overruled and the decree is affirmed at the costs of appellant.
