40 FEDERAL nnronrmn. ment as still in force. Contracts for the services of artists or authors of special merit are personal and peculiar; and when they contain - negative covenants which are essential parts of the agreement, as in this case, that the artists will not perform elsewhere, and the dam- ages, in case of violation, are incapable of definite measurement, they are such as ought to be observed in good faith and specifically enforced in equity. That violation of such covenants will be re- strained by injunction, is now the settled law of England. Lumley v. Wagner, 1 De Cl., M. dz G. 604; Montague v. Flockton, L. B.. 16 Eq. 189, 199. The subject was exhaustively considered by Fnnnnmau, J., in the case of Daly v. Smith, 49 How. Pr. 150, in whose conclusions, in ac- cordance with the English cases above cited, I fully concur. In the present case it is, however, urgedthat the remedy by injunction should not be allowed, on theground that the plaintiff’s damages have been liquidated-by the first article of the contract above quoted; namely, that "f0r each and every breach of this rule the artist shall * forfeit one week's salary ;" and the cases of Barnes v. McAllister, 18 How. Pr. 534; Nessle v. Reese, 29 How. Pr. 382; Mott v. Mott, 11 Barb. 127, 134; and Trenor v. Jackson, 46 How._Pr. 389, are cited in support of this view. · There is no doubt of the general principle that where the damages for the violation of a covenant are either liquidated by the agreement, ’ V or may be easily and definitely ascertained, the pa1·ties will be left to I hllGl1' remedy at law. But it is clear that in cases of contract like the present, the damages are not capable of being definitely ascer- tained or measured; and in the cases first above cited, injunctions were for that reason allowed. The only question in this case, there- fore, which distinguishes the present agreement from those, is whether the provision for the forfeiture of a week’s wages for every violation of article 1 is such a liquidation of the damages as bars the remedy I by injunction. In Barnes v. McAllister and in Nessle v. Reese and Mott v. Mott, supra, there was a covenant to pay a specific sum for failure to observe the covenant in these cases; and these sums were held by the court to be strictly liquidated damages. Where the provision of the contract is in the nature of a penalty, I and not liquidated damages, it is well settled that sucha provision will not prevent the, remedy by injunction to enforce the covenant specifically; and the provision will be construed as a penalty, and not as liquidated damages, where its plain object is to secure a perform- ance of the covenant, and not intended as the price or equivalent to w
