Why, it has been asked, if instinct be variable, has it not given to the bee "the ability to use some other material when wax was deficient? " But what other material could bees use? They will work with and use, as I have seen, wax hardened with vermilion and softened with lard. Andrew Knight observed that his bees, instead of laboriously collecting propolis, used a cement of wax and turpentine, with which he had covered decorticated trees. It has lately been shown that bees, instead of searching flowers for their pollen, will gladly use a very different substance, namely, oatmeal.
