“ Second. That the said institution shall have twelve months from the ■ date hereof within which to complete - such examination and investigation.
“ Third.

The mortgage in question recites the agreement, and it is conceded that the rights of Bainbridge Colby in said agreement and mortgage were subsequently assigned to G-. Byron Lattimer, the secretary of the plaintiff in this action, who now holds said agreement and 'mortgage for the benefit of said plaintiff.
The plaintiff, the Irving Savings Institution, was organized as a savings bank in the year 1851, and the defendant Buxton en-' tered its employ as a clerk in or about the year 1863, and continued in its employ to May, 1893. From the year' 189Q to May,1893, he was the secretary of the institution. In 1873 one Tompkins entered into the employ of said institution, and continued in its employ to May, 1893: There was also in the employ of the plaintiff, during part of the time Buxton and Tompkins were in the employ of the institution, one O. D. Heaton, who in May, 1893, became its president, and a son of O. D. Heaton, who up to' and for some time prior to May, 1893, was a clerk in the employ of said institution.
It was proved on the trial of the cause that in the latter part of April or early in May, 1893, the bank examiners of the state of New York commenced an examination into the condition ■of . said institution, and as a result of such examination it. was discovered that there was a deficiency in its funds of $70,000, or thereabouts. ' Of this. amount over $60,000 had been discovered on, the 4th of May, 1893, of which last-men[205]*205tioned amount $25,000 had been traced directly to the defendant Buxton. On or about the 4th of May, 1893, Buxton was informed of the discovery of this deficiency by the chief bank examiner, and he admitted the existence of a defalcation, but disputed the amount thereof, claiming that it-did not exceed $23,000, and that he had kept track of it himself. He, however, took steps to cover the amount of-so much of the deficiency traced to him, and'in the forenoon of that day placed in the hands of Mr. Heaton, the president of the institution, $25,000 in cash. At this time the examination of the condition of the bank was only partial, and had not been fully completed. On the same day the treasurer of the institution was informed of the discoveries made by the bank ’ examiner, and he thereupon employed counsel to arrange for a meeting of the officers of the institution for that afternoon, to determine upon the steps necessary to be taken in respect to such defalcation. At the meeting which took place in the afternoon of May the 4th, the defendant Buxton was present, and being 'taxed with his defalcation, admitted that he was overdrawn, and claimed to have made the overdraft good by the payment to the presidenjt of the institntion of the sum of $25,000. He was then informed that the deficiency, so far as it had then been discovered, was over $60,000 and he was ui-ged by counsel acting for the institution to take immediate steps to make it all good. He claimed, however, that all over and above the amount paid by him to the president would be found to be errors of bo'okkeeping, and expressed his willingness to give security for all that he was responsible for, directly or indirectly. He was urged to deposit .a sufficient amount in cash to cover the deficiency which up to that time- had been discovered, but stated that he was unable to get the money to do so; and it was finally arranged that he should give a mortgage for the purpose of securing the whole deficiency for which he was directly or indirectly liable. The meeting was then adjourned to a later hour in the afternoon of the same day to the office of the counsel for the institution where, after' discussion, the agreement and mortgage in question were prepared. The agreement at Buxton’s solicitation was phrased in such language so as to give no indication of. the charges which were made against him, and both were executed and delivered to one Colby, as the representative of .the institution.
The investigation into the condition of the institution was then proceeded with, under the terms .of the agreement; - and it was [206]*206finally discovered that it had been systematically robbed by its officers and employees for a period of nearly twenty) years. All but about $14,000 of the total deficiency was traced to the persons who defrauded the institution. The president was found to-be responsible for about $8,000, his son for about $2,000, and Tornp-' kins for about $25,000, and the defendant Buxton $26,382. The investigation and examination disclosed that the defendants Buxton, Tompkins and Heaton, the president’s son, were in the habit of removing from the cash drawer of the bank such sums of money as they required from time to time, entering the amounts taken by them respectively on a slip, which slip was placed in the cash! drawer and was counted as. actual cash in the possession of. the bank at the close of its daily business. Those slips became so numerous that each person taking the money of. the bank charged the amount so taken by him to one or -more of the accounts of depositors with the bank, which accounts each kept for that purpose, and of which the evidence clearly establishes that each had almost exclusive control. ■ The evidence clearly established that Buxton, Tompkins and the two- Heatons, in the taking' and subsequent appropriation by each of-them of the moneys-of the bank, acted in . concert, each aiding, assisting and abetting the others in) the felonious abstraction of the funds of the bank, and for the purpose of preventing the discovery by the trustees of their feloni* ous acts on the occasion of their (the trustees) making the examination of the condition of the bank, which the by-laws and rales required, the defendant Buxton would borrow a sufficient amount of money from outside parties, equal to the amount which had been abstracted by himself and his confederates, deposit the same with the bank, and upon the completion of the examination by the trustees, remove the money so deposited and replace in- the drawer! of the bank the slips, tickets or memoranda heretofore mentioned in lieu thereof. The evidence also establishes conclusively that false statements, purporting to be true and accurate semi-annual statements of the condition of the bank, were mainly' prepared by Buxton, sworn to by him and Heaton before Tompkins, as notary, and subsequently presented to the bank department, -by. which false statements it was intended to cover up the fraudulent misappropriation of the funds of the bank and to- deceive the bank department as to its trae condition.
In the latter part of April or early in May, 1893, the bank was examined, as above stated, by the officers' of the bank department, [207]*207and it appears that a more thorough system of examination was then adopted by said department than that which had heretofore obtained. The result of. the examination showed that the deficiency caused hy the larceny of the funds of the bank amounted, to near $70,000.
The evidence clearly established the. fact that the defendant 'Buxton was the principal person engaged in the conspiracy toi defraud the bank and profited to a larger extent than the others in the amount feloniously abstracted therefrom. Tompkins seems to have profited in an amount somewhat less than that taken by Buxton and the Heatons, father and son, in yet smaller amounts than either.
There can be no doubt whatever on the evidence, which I have carefully considered, that Tompkins and the Heatons, in what they did in the larceny of the funds of the bank, did so with the full knowledge and assent of Buxton.
The defense interposed by Buxton is, First, a denial on information and belief of his indebtedness to the plaintiff in any sum; whatever. Secondly, a denial that the mortgaged premises aré subject, to the lien of the mortgage in question. ■
The principal questions litigated on the trial were: First. The extent of the liability of the defendant Buxton under the agreement which the mortgage was intended to secure. Secondly. The total amount of the deficiency.
Upon the first question it was claimed that the defendant could not be held responsible for any losses which the bank had sustained other than those which were caused by his individual acts. In other words, that he could not be held legally hable for the felonious acts of Tompkins and the Messrs. Heaton, and that by the terms of the agreement in question and the intent of the respective parties thereto, his liability thereunder only extended to the amount abstracted by him individually from the bank. ;
Evidence was introduced on the part of the plaintiff and the defendant in respect to the circumstances existing at and prior to. the time of the execution of the agreement in question. The introduction of - this evidence was provided for in the agreement itself, which, after reciting that it was claimed by the institution or some of the officers thereof that Buxton was indebted to- it in a large amount of money, which indebtedness, if any, was created under circumstances not therein set forth, provided that such circumstances might be shown if the agreement was ever sued [208]*208upon in a court of law or equity, and further, that the amount of such indebtedness was to be ascertained by an examination of the Condition of the bank, which examination was to be completed within twelve months after, the execution of the agreement.
The evidence bearing upon this part of the case convinces me that at the time of the first meeting of the parties, on the 4th. of May, 1893, above referred to, it was clearly understood by both' parties that Buxton should be held liable for all losses sustained by the bank which were caused directly or indirectly by means of his and his associates’ felonious acts which ■ caused said loss, and again on the same day at the second meeting óf the parties, at the office of the counsel for the bank, while the papers'were in process of preparation and when the matter was discussed, it was clearly proved that it was Buxton’s intention not only to secure the bank against the loss sustained by" it by reason of his individual acts, but also by reason of the felonious, acts of his associates. This- was testified to positively by. reputable witnesses produced by "the plaintiff and was denied by the defendant Buxton; He testified that on neither occasion were the words “ directly ” ór “ indirectly ” used, and that it was not understood that he should be held 'liable for any amount exceeding that taken by himself individually. He produced two witnesses who were present, ór claimed, to have been present, during both interviews, and all they testified to, in respect to the use of the words “ directly ” or “indirectly,”' is that they had no recollection of such words being used at either-meeting. '
Buxton’s veracity has been seriously impaired by his own and. other testimony in the case showing that he .willfully swore to-false statements in respect to the condition of the bank, knowing-them to be false at the time he so swore to them. The testimony given in support..of the claim of the bank that such words were-used, and that it was- the intention of Buxton not only to make himself liable for such sums as were traced to him individually,, but for the entire defalcation, whatever it should amount to when discovered, was established by witnesses of unimpeachable character, and this contention seems to be clearly sustained, not only by the testimony of the plaintiffs’ witnesses, but also- by the terms-of the agreement itself, as well as by the surrounding circumstances attending its execution.
As to the second point litigated (the amount of the defalcation), I have examined with great care the evidence bearing upon the-[209]*209question of the amount .of the defalcation, and eliminating such items as have not been proved beyond all question, and crediting defendant with the amount paid by him on the 4th of May, 1893, on the discovery of the defalcation, there appears to be due to the plaintiff, under the agreement and mortgage in question, the sum of $36,030.94. This sum includes interest to the day of , to which day said interest w"as calculated and proved.
Having concluded upon the evidence that by the agreement entered into on the 4th day of May, 1893, that it was clearly the intention of both parties that Buxton’s liability should extend to whatever amount which, under the terms of the agreement, should be ascertained to. have been feloniously taken from the bank by himself or others aiding in its felonious abstraction, it is only necessary to determine whether' the defendant under the proofs in this case is legally liable for the whole amount of the deficiency. An examination of. the authorities, bearing upon that question leads me to the conclusion that he is.
The position occupied by the defendant Buxton in the bank was one of extreme trust and confidence, on assuming which he bound himself by oath to subserve the best interests of the institution and guard its funds as a sacred trust. He exercised a supervision over the other employees of the bank, and whatever was done by them toward creating the defalcation was done with his assent and knowledge, and no effort was made by him, although it was within his power to do so, to protect the bank and its funds, or even to notify the trustees of the felonious acts of his associates.
In Commercial Bank v. Ten Eyck, 48 N. Y. 307, the court said: “The defendant, as cashier, was a financial agent of the plaintiff, intrusted to some extent with the management of its affairs; As such agent he was bound to exercise reasonable skill and ordinary care .and diligence in the discharge of his duties. If he failed in such skill or omitted such care and diligence, andj in consequence thereof the plaintiff suffered damage, he is liable to respond; and much more is he liable to respond if he caused any damage to the plaintiff by any illegal, fraudulent or tortious act.”
This rule grows out of the duty which every agent owes his principal to exercise ordinary diligence in the protection of the interests of his principal — such diligence as a prudent man under the circumstances would display about his own affairs — and is supported by many authorities, among which may be cited Hun [210]*210v. Cary, 82 N. Y. 65; Scott v. Depeyster, 1 Edw. Ch. 513; Austin v. Daniels, 4 Den. 299; Hobart v. Dovell, 38 N. J. Eq. 553; Rochester City Bank v. Elwood, 21 N. Y. 88.
In the. case of Hobart v. Dovell, above cited, the action was to. •compel the receiver of a bank to account for the rents and profits •of certain property which had been conveyed to the bank. It was admitted that the conveyances were for security only, and it was proved that they had been executed under the following circumstances: The son of the defendant had been a teller of a bank. He had permitted the cashier to embezzle moneys óf the bank, and made'under his directions' certain entries which covered up the shortage. On the discovery of the shortage,, the defendant having been informed of the fact, and of her son’s claim that he had taken none of the money, conveyed the property as security for any deficiency that might be against him. The contention was that this covered only such sums as he might personally have taken,- and if he had taken nothing, then she was entitled to a reconveyance and an accounting of the rents • and profits. The court held as follows: “ Our conclusion is that it was designed to-indemnify the bank, not only for funds abstracted by Dovell himself, but also for all of the deficiency for which he was civilly responsible. * ' * * The testimony hitherto produced indicates that the deficiency arose in whole, or in great part, from the embezzlement, by the cashier, of moneys in the hands of Dovell, ■ the teller. Some -of the cashier’s transactions were of such a nature that it is difficult to believe that the teller was not apprised of their dishonest or unauthorized character, yet, nevertheless, he lent himself to their furtherance by actually delivering to the cashier the money which he asked for, and concealing the facts beneath false statements in his accounts. For knowingly assisting in such an abstraction the teller would be as responsible to the bank as if he' had spent the money himself. He was an officer of the bank, having certain prescribed duties, for the faithful performance of which, he was bound directly to the corporation. No orders of the cashier could exculpate him in the breach of those obligations. Within the. scope of the cashier’s authority, and sc long as he was apparently acting on behalf of the-corporation, the cashier’s directions might control the teller, and the latter mighl . not be required do look beneath the surface of his superior’s acts But when he was led to believe that the . cashier was violating hi own duty to the bank, and was taking the bank’s funds for hi [211]*211own ends, irregularly, and without authority from the directors, the teller had no more right to aid or connive at such misappropriation than if it were being perpetrated by a stranger. The same principle would hold if the embezzler were a "director or the president. Such misconduct on the part of Dovell we think the evidence tends to establish in more than one instance; and so far as it helped to effect a loss to the bank he is answerable.”
In respect to the point which has been urged on behalf of the defendant as to the construction to be given to the agreement in question, and to the use of the words “ indebted ” and “ indebtedness ” as limiting the defendant’s liability to such sums as he himself feloniously abstracted from the bank, it is sufficient to say in addition to what has been said upon the subject that the testimony, as to the surrounding circumstances and conversations which lead up to the execution of the agreement was competent to explain the sense in which the term “ indebtedness ” was used. Blossom v. Griffin, 13 N. Y. 569; White’s Bank of Buffalo v. Myles, 73 id. 335.
In this latter case evidence of surrounding circumstances was admitted, and in the case of French v. Carhart, 1 N. Y. 96, the court say: “ Too much regard is not to be had to the proper and exact signification of words and "sentences, so as to prevent the simple intention of the parties from taking effect, and whenever the language used is susceptible of more than one interpretation the court will look at the surrounding circumstances existing when the contract was entered into, the situation of the parties and of the subject-matter of the instrument. To this extent, at least, the well-settled rule is that extraneous evidence is admissible to aid in the construction of written contracts.”'
But, as already shown, the agreement, by its terms, provides for the admission of "testimony of this -character. Other authorities might be cited bearing upon this subject, but it is not deemed [necessary to refer to them. Upon the whole case I am of the opinion that the plaintiffs are entitled to the judgment prayed for, •with costs. .
Judgment for plaintiffs, with costs.
