Terra Cotta.—Is somewhat more difficult. The Trocadero uses raw Siena and red ochre, but a little experimenting will be necessary before a wholly satisfactory result can be obtained.
Wood.—Yellow ochre, van Dyke brown, raw Siena and black.
Bronze.—A dull brown or green bronze can easily be obtained by using a large proportion of color in the turpentine and wax mixture. Should the gold lights be desired, however, the cast must first be shellaced, then gilded, then shellaced again, and finally painted over with green or brown of the appropriate shade.

This should stand for some three or four days and then be rubbed down and polished with soft, clean cloths. A little zinc white added to the mixture will give a still better color.
Stone.—A very satisfactory process is the following: Dissolve a small amount of sculptors'
