Plaintiffs sued defendant for taking timber alleged to be their property. He claimed title as having purchased it from William Frne, the agent of the plaintiffs, and also of tbe South Pewabic Company, to apply in payment upon a bill of mining powder and fuse, which was due him from the latter company.
There is no dispute about the important facts in the case, which were in substance, so far as essential to the exceptions alleged in tbe cause, as follows:
Both companies were organized mining companies at *75Portage Lake, in the Upper Peninsula, mainly owned by the same parties in interest, and employing the same general agent, .Captain Frue. In the spring of 1870, and for some months previous, vrork had been suspended on the Adams mine, to await developments on the same lode in the South Pewabic. The supplies of both companies were-kept together, and Frue was authorized to use the Adams supplies for the other company in his discretion, debiting them, when wanted, to the South Pewabic. The Adams Company had on hand the timber in question — about twenty-six thousand feet — a year or more before the transactions in controversy, and Frue had been directed in 1868 to dispose of it if he could. There was some dispute as to the precise character of his instructions at that time. The timber was not wanted for any purpose of the Adams mine. In the spring of 1870, the South Pewabic was short of powder and fuse, and had run up an unpaid bill with Senter of about five thousand dollars, and, unless it was arranged, he was unwilling to furnish any more. Frue proposed to him, and it was finally agreed, that he should take this lumber at seventeen cents a foot. The bargain was closed, and a new account was afterwards opened for the desired articles, which ivas not paid up before the company failed, or stopped operations, and is still unpaid.
Frue put the timber in charge of one Ames to take charge of it for the South Pewabic Company. The timber was in rafts, and moored at the premises of the South Pewabic. He afterwards was directed to take charge of it for Mr. Senter, and was employed by mutual consent to measure it. He removed it for defendant to the other side of the lake, Mr. Ball, claiming to act for plaintiffs, objecting, and claiming it to be their property.
The jury found for the defendant.
The questions presented can be best disposed of by *76combining such of them as are not distinct. Much of the controversy turns on the powers of Captain Frue, the mining agent. Both companies had their principal offices in Boston, and Elisha T. Boring of Boston was president of both, and Charles II. Palmer of Pontiac, the only Michigan director in either company.
It was claimed that these corporations had no power to buy or deal in timber, and that, for this reason there could be no agency in Frue to do what could not be done by his principals. But this is not to be supposed. It appears this timber was originally designed for use by the Adams Company, and whether it had been so designed or not, we are bound to know that in mining operations, as well as in the auxiliary work .connected with . them, timber'is indispensable for some purposes, and capable of use for many. It would require a very plain case to justify a court in holding, as a legal proposition, that any such corporation might not become lawfully possessed of such property, and we cannot, in advance, and without some manifest necessity, assume that such cases are to be found.
The next question refers to the extent of Frue’s authority, independent of specific and expressly granted powers. We are not satisfied that any testimony would be needed to show the extent of the ordinary powers of an agent in charge of such a mine. The authority of such officers must, within the usual range of business, at least, be recognized judicially, like that of bank cashiers, vessel captains, and other known agents. The mining law recognizes agents by name, as known representatives on whom process may be served. They are the persons who have charge, personally, of the local business at the mines, and are necessarily to be treated in law as general agents, to do all that is fairly within the scope of corporate business in conducting the operations in that locality. The testimony of Mr. *77Palmer, -which shows the usual range of such agencies, indicates no more than should be inferred. . The business could not be conducted at all without a very wide discretionary power. There is no reason, and can be no legal principle, which will put the agent of a corporation on any different footing than the agent of an individual, in regard to the same business. A general agent needs no instructions within the range of his duties, and any limitations on his usual powers would not bind others dealing with him and not warned of the restrictions.
So far as any instructions from the corporation authorities are concerned, they would, as between the agent and his principals, govern his liability. There is no legal presumption as to the powers of the president of a mining company; but as Mr. Loring’s acts have been assumed in this case to be authorized, they must be so considered in this court, and it is probable they were so in fact authorized, so far as they were material.
The question next arises, how far the double agency of Captain True affected his relations to his employers and to third persons. It was claimed that upon the principle that a man cannot contract with himself, and cannot occupy positions involving a conflict of duties, all of his dealings whereby the property of one company was transferred to, or used for, the other, should be held unlawful. There is no validity in such a proposition. The authority of agents may, where no law is violated, be as large as their employers choose to make it. There are multitudes of cases where the same person' acts under power from different principals in their mutual transactions. Every partnership involves such double relations. Every survey of boundaries, by a surveyor jointly agreed upon, would come within similar difficulties. It is only where the agent has personal interests conflicting with those of his principal, *78that the law requires peculiar safeguards against his acts. There can be no presumption that the agent of two parties will deal unfairly with either. And when they both deliberately put him in charge of their' separate concerns, and there is any likelihood that he may have to deal with the rights of both in the same transactions, instead of lessening his powers, it may become necessary to enlarge them far enough to dispense with such formalities as one man would use with another, but which could not be possible for a single person to go through with alone.
When these two mining companies appointed Frue to act as their agent in charge of their respective mines, it is not supposable that either expected him to have less authority than if two agents had been chosen, one for each. And it would follow, of necessity, that under such an appointment, if any case should arise in which the agent of one mine would have legitimate occasion to deal with the agent of another mine, within the usual range of agency business, the one agent occupying the place of two such agents, must have the same power to dispose of such matters, or else the mine must suffer. The common-sense inference from such a double appointment would rather be, that if there should be any difference, it should be towards a more intimate relationship in business than where the agencies were separate. And in the present case the evidence shows such an intent, going beyond what would probably be usual in most cases.
One inevitable result must be, that by all persons not actually notified to the contrary, his disposal of any property in his hands, in such manner as miniug agents usually act, will, and should be, assumed as lawful. Each company having given him power to act over its concerns, it will be impossible, by reason of that holding out, for any one to know on whose behalf he deals, or whether he has a right *79to deal, except from his own representations. The employers who put him in such a position must be estopped from questioning the acts they have so plainly authorized and enabled him to do.
In the present case, the timber was subject to sale by the agent of any company that owned it. The Adams Mining Company had distinctly authorized their supplies to be used for the purposes of the South Pewabic. It was not necessary, in order to carry out such a purpose, that the title should first pass from one company to the other, in any formal way, or at all. The act of an agent representing them both, would be as effectual as their joint transfer to any third person, purchasing. As between themselves, the only possible adjustment must be by a transfer of credits on account, or a deposit, or shifting of funds to the private account of the proper company.
If Captain Frue, in the exercise of his judgment, determined that it was necessary to adjust or secure an outstanding powder account, as the best means for obtaining further necessary supplies, we think it was within his agency to do it. And if he was authorized to use the supplies of the Adams Company for the South Pewabic, we see no reason for holding that such an appropriation would be less legitimate than if the timber had originally belonged to the latter company. It was a reasonable and fair use of discretion in the choice of means to reach what was essential to the mining business. If Mr. Senter had been informed of the whole facts, he would have been justified in relying on Frue’s authority.
After the contract was made, Frue did all that was possible to effect a delivery. Such delivery must necessarily be constructive, and the agent in charge of the timber, having been instructed, and having undertaken, by the joint directions of Frue and Senter, to hold it for the latter, the deliv*80ery was complete. The whole property being identified and sold, at a fixed price per foot, the process of ascertaining the amount was not essential to passing the title, as it might have been if less than the whole amount delivered was to he sold and separated by measurment. In that case, the measurement might be necessary to fix the identity of the property sold. But where all is sold, no such process is needed to pass title. The ascertainment of the price was a mere mathematical computation, involving no further action to bring the minds of the parties together.
Assuming that Mr. Ball, who acted on behalf of the plaintiff, had authority to overrule the action of Captain Frue, and that his notice was given to Senter himself, it was too late to affect his rights, when the sale was complete already.
These considerations dispose of all the errors assigned, and it will not he necessary to refer to them specifically. The judgment was correctly given, and must be affirmed, with costs.
The other Justices concurred.
