In ordering glass eyes it is often best to get them in the clear glass iris with black pupil so they may be given any color desired by painting the backs with tube colors, afterward protecting the paint with varnish. In this way a small stock will answer for many varieties. The plain black eye which is the least expensive can be used for many of the smaller birds and mammals, but should never be when the iris of the eye has any distinct tint. Do not make the mistake of ordering an assortment of "off" sizes and colors, that is those which are seldom called for. Aim to have those on hand for which you will have the most frequent use, the exceptions can be quickly had by parcel post. There is more demand for eyes of some shade of yellow or brown than any other colors, probably.
