delivered the opinion of the Court. [After stating the facts.] So that the only question is, whether the breach is well assigned, and whether the condition, as to this part of it, is valid in law ; for it is admitted that if it is, it is not vitiated by any illegality in the other stipulations in the condition.
The question then is, whether any agreement which may be supposed to discourage competition in trade, is unlawful, and is such a restraint of trade as is inconsistent with public policy.
In the case of Mitchel v. Reynolds, 1 P. Wms. 161, Parker C. J. lays down the reasons why restraints of trade are not allowed.
“ The true reasons,” says he, “ of the distinction upon which the judgments in these cases of voluntary restraints are founded, are 1st, the mischief which may arise from them first to the party, by the loss of his livelihood, and the subsistence of his family ; secondly, to the public, by depriving it o, a useful member.”
“ Another reason is, the great abuses these voluntary restraints are liable to ; as for instance, from corporations, who are perpetually laboring for exclusive advantages in trade, and *192to reduce it into as few hands as possible. As likewise from masters, who are apt to give their apprentices much vexation on this account, and to use many indirect practices to procure such bonds from them, lest they should prejudice them in their custom, were they to set up for themselves.”
“ 3dly, Because in a great many instances, they can be of no use to the obligee ; which holds in all cases of general restraint throughout England ; for what does it signify to a tradesman in London, what another does at Newcastle ? And surely it would be unreasonable to fix a certain loss on one side, without any benefit to the other.”
“4thly, The fourth reason is in favor of these contracts, and is, that there may happen instances wherein they may be useful and beneficial, as to prevent a town from being overstocked with any particular trade.”
These are the principal reasons given for the rules of law in respect to the restraint of trade by voluntary contract, and nothing important can be added from the later cases on the subject. They were collected to a recent date by Chitty in his Digest of laws relating to commerce, and none of them have much bearing upon the question under consideration.
It must therefore be decided on general principles, rather than by express authority. Whether competition in trade be useful to the public or otherwise, will depend on circumstances. I am rather inclined to believe, that in this country at least, more evil than good is to be apprehended from encouraging competition among rival tradesmen or men engaged in commercial concerns. There is a tendency, I think, to overdo trade, and such is the enterprise and activity of our citizens that small discouragements will have no injurious effect in checking in some degree a spirit of competition. An agreement with a tradesman to give him all the promisor’s custom or business, upon fair terms, and not to encourage a rival tradesman to bis injury, can hardly be considered as a restraint of trade. Certainly it is not such a restraint as would be injurious to the public, for in proportion as it discourages one party it encourages another. As to the public therefore such a contract stat indifferenter. It would be extravagant to sup*193pose that any one, by multiplying contracts of this kind, could obtain a monopoly of any particular trade. But admitting that such a contract is a restraint of trade, yet it is clearly a limited restraint, and is not binding by the terms of it beyond the sphere of the obligee’s actual business. Such a particular restraint made by voluntary contract on good consideration, is valid in law.1 And the consideration appearing by the condition in this case is as we think a reasonable one, and sufficient to support this part of the agreement. The plaintiffs agreed on their part to do all the defendant’s freighting up and down Connecticut river, at the customary freight, and to be paid in goods at the usual price. This agreement on the plaintiffs’ part is to be inferred by their acceptance of the bond, in which the defendant agrees to give them his freighting, and to aid and countenance them in the business of boating, and not to promote any other boatman to compete with them in the business of boating This seems to be a fair and equal bargain, founded on a good and adequate consideration. If there is any inequality the hardship and inconvenience are evidently on the part of the plaintiffs, who are bound to be ready at all times to take the defendant’s freight, however inconvenient it may be to them so to do.
But it is said that this is a useless and unnecessary contract, and therefore not to be enforced by law; that the plaintiffs have not shown in the pleadings any actual damages. But the plaintiffs in assigning a breach are not obliged to set out their claims for damage ;2 it is sufficient to assign a breach, and the breach is in substance well assigned; if there be any formal defect it cannot be taken notice of on general demurrer.
As to the first branch of the condition we do not decide. That may be the subject of further consideration on a hearing m chancery, in which case it may be necessary to ascertain other facts than those appearing on the pleadings. One fact in particular appears to be important, namely, whether the plaintiffs are in fact engaged in boating up and down the river coextensively to the terms of the condition. If not, the ques tion will arise whether a restraint can be valid which can be of no use to the plaintiffs, and which may be prejudicial to the rights of the defendant.1
Replication adjudgea good.

The consideration for, as well as the extent of, the re straint, must be taken into the account, and if from a view of these the restraint appears greater than is necessary for the protection of the party, who imposes it, in the full enjoyment of his trade, or is otherwise unreasonable, the agreement creating such restraint cannot form the subject of an action.

The proper question in such cases is, whether the restraint is such only as to afford a fair protection to the interests of the party in favor of whom it is granted, and not so large as to interfere with the interests of the public. Horver v. Graves, 7 Bingh. R. 735; Pierce v. Woodward, 6 Pick. 206
