348 be. So far as he expresses his principal's assent to be bound to terms to be fixed by the agent, he is a mere messenger; in fixing the terms he is a stranger to the contract, which stands on the same footing as if it had been made before his personal function began. The agent is simply a voice affording the marks provided by the principal's own expression of what he undertakes. Suppose a wager determined in amount as well as event by the spinning of a teetotum, and to be off if numbers are turned up outside certain limits; is it the contract of the teetotum?

If agency is a proper title of our corpus juris, its peculiarities must be sought in doctrines that go farther than any yet mentioned. Such doctrines are to be found in each of the great departments of the law. In tort, masters are held answerable for conduct on the part of their servants, which they not only have not authorized, but have forbidden. In contract, an undisclosed principal may bind or may be bound to another, who did not know of his very existence at the time he made the contract. By a few words of ratification a man may make a trespass or a contract his own in which he had no part in fact. The possession of a tangible object may be attributed to him although he never saw it, and may be denied to another who has it under his actual custody or control. The existence of these rules is what makes agency a proper title in the law.

I do not mean to assume in advance that these rules have a common origin because they are clustered round the same subject. It would be possible to suggest separate reasons for each, and going farther still, to argue that each was no more than an application, even though a misapplication, of general principles.

Thus, in torts it is sometimes said that the liability of the master is "in effect for employing a careless servant," repeating the reason offered by the pseudo-philosophy of the Roman jurists for an exceptional rule introduced by the prætor on grounds of public policy. This reason is shown to be unsound by the single fact that no amount of care in selection will exonerate the master; but still it might be argued that, whether right or wrong, this or some other notion of policy had led to the first of the rules which I selected as peculiar, and that at most the liability of a master for his
