delivered the opinion of the Court:
J. Louis Pfau, Jr., the appellee, brought an action of assumpsit to the March term, 1883, of the Adams county circuit court, against John Schmidt, (the appellant,) John L. Pfau, Sr., and Theodore Brittenberger, as partners, lately doing business under the firm name of “¿Etna Iron Works, ” to recover for work and services claimed to have been rendered by him as general manager of the company, from the 25th day of February, 1877, to the 25th day of February, 1880. There was no service on Brittenberger. Defendant Pfau admitted the justness of plaintiff’s claim, and consented that judgment might be rendered against him. Pleas of the general issue, Statute of Limitations, and set-off, were filed by Schmidt, and the cause was tried before the court and a jury, resulting in a verdict and judgment in favor of plaintiff, for $3600, which Avas affirmed by the Appellate Court for the Third District, and Schmidt alone appealed to this court.
The partnership in question was formed in 1875, for the purpose of carrying on a foundry and machine shop at Quincy, Illinois. At that time appellant was engaged in the practice of medicine, and Pfau, Sr., was carrying on other branches of business on his own account, namely, the manufacture of hot-air furnaces, and the galvanized iron and tin and stove business, and the evidence tends to show that these two members of the firm,—particularly the latter,—were expected to give but little, if any, of their personal attention to the business of the company. The understanding seems to have been, that in discharging their share of the labor and duties pertaining to the business, they were to be respectively represented by their sons, the appellee, and Albert Schmidt, a young man then about eighteen years of age, under the general supervision of Brittenberger, who was t'o give his personal attention to the affairs of the concern. Under this *498arrangement neither of the sons was to receive from the company any compensation for his services. The business of the partnership was continued under this arrangement until the latter part of 1875, when Brittenberger abandoned the concern, and its management thereafter devolved mainly upon appellee,, without any other or, different understanding,- and it so continued until the 25th of February, 1877, when, as claimed by appellee, it was mutually agreed between himself, his father and appellant, that young Schmidt should retire from the business, and that appellee should take charge of it as chief manager, and give, to it his undivided time and attention.
That appellee did serve as manager of the concern for three years, from the 25th of February, 1877, is conceded. But it is claimed by appellant, that appellee’s compensation was fixed at $300 and traveling expenses for the first year, and that by a subsequent agreement he was to receive after the first year, in lieu of a fixed salary, a commission on sales—ten per cent on small jobs and three on large ones. This alleged agreement, so far as it relates to compensation, is positively denied by appellee, the latter claiming that that matter was left open and unsettled. It is also claimed by appellant that appellee did not give to the, business his entire time and attention, as he had agreed to do, and that by reason of its neglect, and his unskillfulness and bad management, the company sustained heavy losses, and the business proved a failure. These several' claims of the appellant are distinctly denied by appellee, and the evidence relating to the subject is conflicting and wholly irreconcilable. Such being the case, it is hardly necessary to add that the issues thus raised must be regarded as conclusively settled in favor of appellee by the judgment of affirmance in the Appellate Court. The errors relied on for a reversal, here, question the correctness of the ruling of the trial court upon the admissibility of evidence, and in the giving, refusing and modification of instructions. *499It appears that on the 25th of February, 1880, the parties met at their business office for the purpose of a general settlement, at which it was determined to stop and wind up the business. Appellee, in speaking of this meeting in his testimony, incidentally stated as his opinion that the partnership business .was thus suddenly terminated because.he told appellant he would not work for $300 a year. Upon his cross-examination he was asked this question: “Was not the true reason of this firm quitting business that it had lost money from beginning to the end ?” The court, upon "objection, held the question improper, and this is assigned for error. The ruling of the court in this respect affords no ground for reversal. The answer to the inquiry, let it have been the one way or the other, would have had no bearing upon the merits of the controversy or the issues submitted to the jury. The main question for their determination was, what, if anything, did the defendants owe the plaintiff on account of his services prior to their stopping business. The answer of the witness, .if responsive to the question, would, at most, have been but the expression of an opinion upon a mere collateral matter, and on this ground, the question, to say the least of it, was of doubtful propriety, and, consequently, within the discretion of the court to allow it or not, as it thought proper. The -parties had a clear right to stop business at the time they did, without regard to the motives or reasons that induced them to do so, and hence any evidence on that subject would more than likely have diverted the attention of the jury from the real issues involved. In any view, we perceive no error in disallowing the question.
It is also claimed that the court erred in refusing to permit Pfau, Sr., to answer, on cross-examination, the following question: “Do you think during 1877 the profits of yourself and Louis, or your share of the profits, amounted to $2000 ?” The object of this inquiry was to show that the business of Pfau, Sr., in a' part of which appellee had an interest, was *500successful, while that of the ¿Etna Iron Works was unprofitable, leaving it to be inferred by the jury, that appellee had fostered the business, of himself and father to the neglect of that of the firm. Waiving the competency of the evidence offered, which, to say the least of it, is extremely doubtful, we do not think it was proper on cross-examination. It was not germain to anything called out on the direct examination, and if admissible at all, it was clearly matter in chief. The court therefore ruled correctly in holding it improper. The only pretence for asking it is the witness’ statement, on redirect examination, that appellee “spent pretty much all his time” in the employment of the firm. Upon what principle this statement would authorize appellant to go into a general inquiry as to what profits the witness, or the witness and his son, were realizing in a wholly different business, and one in which the appellant had no concern, is not perceived. There is clearly no merit in the objection.
It is further objected, the court erred in not permitting appellant to prove the general reputation of the work done at the ¿Etna Iron Works during the years covered by appellee’s service. We are aware of no precedent for the admission of such evidence under like circumstances, and are satisfied that the general principles upon which it is admissible at all, have no application to the case in hand. The issues in it are very simple. The plaintiff sued to recover for three years’ services as business manager of the defendants. One of the defendants admits the justness of the claim, and the other denies it. The appellant says, “True, you worked for us that period of time, but you neglected our business, and did not do your work properly, by reason of which we have sustained damages, which we seek to recoup in this action.” Upon the issue thus tendered by appellant, the burden was upon him, and it could not be established by evidence of the character offered. If, as claimed, the plaintiff neglected the business of the firm or did their work improperly, that was a fact sus*501ceptible of direct proof, and as a matter of justice to him, the particular acts of improper conduct or omissions of duty on his part should have been specifically pointed out, so as to have enabled him to meet the charge in an equally direct and specific way. Suppose it be conceded the reputation of the products of the establishment for the period in question was bad, it does not necessarily follow that it resulted from the plaintiff’s neglect of duty. Moreover, the bad reputation of the work may have been undeserving, or it may have been caused by the original improper construction of the establishment, or the character of the machinery put into it. This bare suggestion shows the impropriety and danger of admitting such evidence, even if it were not objectionable on the ground already stated. The probable effect of admitting such testimony, would be to incumber the case with numerous collateral issues but remotely bearing upon the real merits of the controversy.
At the settlement of the 25th of February, 1880, appellee made a statement in writing, showing the state of the partnership account between appellant and Pfau, Sr., which is annexed to his testimony as “Exhibit A, ” one item of which, as already seen, was placed there by appellee under protest. Counsel for appellant, referring to this statement, asked the witness Schanz, who had also prepared a statement relating to the condition of the partnership accounts, the following question: “Mr. Schanz, I place in your hands a statement, and I will ask you how that statement corresponds with the result of your examination of the books as to the indebtedness, or the amount of money these partners of the iEtna Iron Works put in business.” The court, on objection, held the question improper, and its ruling in this respect is assigned for error. We do not think the point is well taken. On the contrary, we regard the question improper, both in form and substance. If appellee committed any errors in keeping the partnership books, by which appellant sustained loss, it would *502have been permissible to show that fact; but the proper course in such case ivould have been to ask the witness whether, upon his examination of the books, he found any errors, and if so, to state what they were.. Yet, even if the court had erred in disallowing this question, the appellant was not prejudiced by it, for this witness seems to have testified fully as to the condition in which he found the books, and as to appellee’s method of keeping them, and the whole matter was before the jury.
Again, it is objected the court erred because it would not permit appellant to give his opinion as to the effects of appellee’s management upon the profits and losses of the concern during the three years he controlled its affairs. The court clearly ruled properly on this question. As already indicated, if appellee had been guilty of any improper conduct in the management of the company’s affairs, it was a matter susceptible of proof, and the evidence should have been directed to that issue. Perilous, indeed, would be the position of a general manager, if he could be held personally responsible for a failure of the business, upon the mere opinions of witnesses as to the character of his management, based largely, perhaps, upon the very fact of the failure itself. Where one is clothed with a general discretion in the management of the business of another, as was the case here, he will not be held responsible for an honest mistake in its exercise, provided he has acted with reasonable skill and ordinary diligence. In such case there is no implied guaranty of the success of the business on the part of the agent, and if losses occur, the principal must bear them.
In respect to the remaining exceptions not specially noticed, it is sufficient to say, in general terms, we do not regard any of them well taken. They are, in many respects, much like those considered, and the general observations already submitted apply with equal force to them.
*503At the instance of the plaintiff, the court gave to the jury the following instruction:
“In respect to the Statute of Limitations, set up by the defendant John Schmidt, the jury are instructed that if the plaintiff performed the labor and services for which the suit is brought, by the year, at the request of the defendants John Schmidt and John L. Pfau, as two of the partners in the ¿Etna Iron Works, and no time was fixed as to when such labor and services were to be paid for, the law would presume that they were to be paid for at the end of the year; and if the first year ended any time after the 21st day of February, A. D. 1878, then no part of such labor and services would be barred by the Statute of Limitations, and the jury should find that issue for the plaintiff. ”
The instruction is objected to on two grounds: First, it is said by counsel, “it does not connect itself with the evidence anywhere or by any terms, but simply states that if the plaintiff performed the labor and services for which the suit is brought, by the year, at the request of the defendants, then the law is so and so, ”—or, more shortly put, as we understand this branch of the objection, the instruction does not'contain the usual formula, “if the jury find, from the evidence,” etc. The omission of these words, under the circumstances, we regard as Avholly unimportant. It was a conceded fact that appellee worked for the company three years, and that there had been no settlement, or attempt at settlement, between the parties, on account of his services, until he stopped work altogether on the 25th of February, 1880, and appellant himself swears that it was the original agreement to pay appellee $300 a year. Assuming this to be true, there was no ground whatever for interposing the Statute of Limitations, for the five years did not commence running as to the first year’s sendee until the 25th of February, 1878, and the suit ivas commenced on the 21st of February, 1883. Where an in*504struction, based upon a fact conceded by the party against whom it is given, properly declares the law, upon the hypothesis that the admitted fact is true, it will be no objection to the instruction that it does not contain the words, “if you believe, frovi the evidence.” The same rule applies in any case where an instruction sets forth a state of facts hypothetically, about which there is no controversy in the evidence. It is only where the facts, hypothetically stated, are controverted by the party against whom the instruction is given, that the formula, “if you believe, from the evidence,” etc., becomes important.
It is claimed, in the second place, there is no evidence in the record upon which to base this instruction. This claim is clearly without any foundation, as is fully shown by what we have already said. In addition to this, it is an undeniable fact that at the meeting of the parties on the 25tli of February, 1880, the claim of appellee for his services was conceded by all of them as an existing indebtedness, and the only controversy was as to the amount. The appellant on that occasion, according to the testimony of appellee, in referring to this claim, said: “This matter of salary has not been settled yet,—we oive you for three years’ salary,”—and we fail to find any denial in the record of the statement thus attributed to appellant, and it is hardly necessary to add, this admission of appellant clearly took the case out of the statute, even if his salary had been payable monthly. The answer of appellant to-this is to the effect that if his téstimony is looked to for the purpose of proving any particular fact, it must be accepted as a whole, and for all purposes. This view of the law is clearly unsound, and finds no support from English or American authority. It is a familiar principle of the. law of evidence, as it obtains in this country and in England, that the statements of a party made against his own interest may be accepted and acted upon by the jury as true, while others made in his favor, though at the same time and as part of *505the same conversation, -may be rejected as unworthy of belief. In such case, all that the witness has said relating to the particular matter in question goes to the jury for their consideration, but when considered, they may believe such parts of the statement as seem reasonable and probable, and reject the balance. 2 Best on Evidence, sec. 520.
There are other exceptions to the rulings of the court upon the instructions discussed in appellant’s brief, but we do not regard any of them as well taken, and as the present opinion is already extended beyond desirable limits, we do not deem them of sufficient importance to discuss them in detail.
The judgment will be affirmed.
Judgment affirmed.
