¶1delivered the opinion of the court.
¶2It is conceded that the contract on which this action is f0 unded, was made by the defendant, and that, if it can in *473its nature be considered as assignable, it has been duly assigned to Breck.
¶3Nor is it disputed, that there has been a breach of the contract on the part of the defendant, if the assignment gave Breck a right to have his hides tanned under the contract. The declaration of the defendant to Breck, that nothing was clue, and that he would not tan hides for him under the contract, rendered an actual offer of the hides to the defendant to be tanned unnecessary.
¶4But it is insisted, on the part of the defendant, that the contract was not in its nature assignable, and that Breck acquired no right to have hides tanned under it.
¶5There are cases, without doubt, where a contract cannot be assigned, even in equity, without the consent of both parties. Instances of this kind may be found, where young men contract to labor for farmers by the month, or the year, and where it is understood that they are to labor on the farm, live in the family, and be under the direction of the hirers. In such cases these circumstances become a part of the contract, and they are not bound to labor on other farms, under the direction of other persons, or to live in other families, without their consent.
¶6And it is possible that there may be cases in which, where one man contracts to manufacture articles from raw materials to be furnished by another, the contract must be understood to mean materials belonging to him by whom they are to be furnished. No case has, however, occurred to our minds where this must be considered as the understanding. For, in general, he who is to furnish materials in such a case would have an undoubted right to do it by an agent: and whether the materials are to be furnished by an agent or by an assignee must be a matter of very little importance to the manufacturer.
¶7But admitting, for the present, that this contract was not assignable without the consent of the defendant, still it was *474very clearly so with his assent. And is there not enough disclosed in this case to show his assent ?
¶8When Breck told the defendant he had the contract, the defendant made no objection ; and in such a case, silence is consent. If he had any objection, he was bound to state it, and give Breck an opportunity to return the contract to the payee, if he chose. Having made no objection, then, the defendant’s lips are closed on that subject forever. 5 N. H. R. 277, Albee vs. Little.
