Supply of food and demand for it is one of the important factors to be considered in the struggle for existence, a factor that insistently demands proper attention on the part of every organism in its solution of the problem whether it shall exist or shall not. Many students have observed, many have killed and dissected hundreds and thousands of animals in determining what is the character of the food supplies of various species living in the water above ground, and on the surface of the earth, but not many it seems have entered seriously into the determination of the food of those living in the waters under the earth. We have a sufficiently satisfactory knowledge of at least a part of the food of the Chinch bug the Codling moth, and the Boll worm, but we know little about the food of the subterranean animals.
