The defendants are extensively engaged in the manufacture of carpets. The value of their products in the market and the demand for them by purchasers depend largely upon the artistic character of the patterns or designs upon which they are made, and the harmony and general effect of the shades of color by which they are brought out. The designs are prepared by persons employed for that special purpose. When a new design has been made and adopted by the manufacturers, it is sent to the color room, which is in charge of a color mixer. The duty of the color mixer is to prepare the dyes or colors so as to reproduce in the carpet all the shades indicated by the design. He submits the results of his work to the designer. When approved, it becomes his duly to enter in a book kept for that purpose and called a “ Color Book,” the number of the carpet and the formula by which each shade of color used in its manufacture is produced.

If the plaintiff had a light to recover in this action because of the ownership of the books in which the recipes had been entered and the manner of his detention, when he attempted to take them away, the jury should have been instructed that the value of the recipes was not to be considered in estimating the damages. As between these parties, as we have already said, the plaintiff had no exclusive right to thorn. It was his duty as a color mixer to enter each formula in his employer’s books. They had a clear legal right to the knowledge which such a record would afford them, and the copies they have made from his books should have been made for them by the plaintiff as the several colors were compounded during his long term of
The judgment is reversed for the reasons now given and a venire facias de novo awarded.
