When we study the habits of animals in a truly sympathetic way and become thoroughly acquainted with them and with the work that each one is performing, we shall see that each one has its place in the economy of God's world, that each has its part to play, and that even so far as the animal world is concerned we are all related and inter-related. If we destroy or permit to be destroyed that marvellous balance which the Divine Power has instituted in the Universe, we do it at our own peril. Instead, then, of being the enemies of the animal world, instead of being its persecutors and its destroyers, we should be its friends and helpers.
