From the female scorpion we acquire fresh veneration for the possibilities of maternal devotion. The mother of the Gracchi has been well advertised because she preferred her sons to jewelry. The Russian mother who feeds herself to the wolves, instead of throwing her boy over the back of the sleigh in the usual way, is also highly praised. But their devotion shrinks to nothing when compared with that of any poor mother scorpion of Mexico's sandy tracts. As soon as her young scorpions arrive, they climb to her back, half a hundred of them or more. She moves about with them, protecting them, avoiding danger, giving them the sunlight. Meanwhile they are feeding on her body. Her movements get gradually slower and slower; finally they cease. The young scorpions depart leaving the mother scorpion simply an empty shell. We should dislike to see any such exhibition of tenderness among human beings, but we can't help admiring the scorpion. Mr. Scorpion, placed as was Captain Dreyfus, would sting himself to death. They are a determined race. ---- Spiders who construct tiny balloons with little cars all complete are wonderful creatures. They cross chasms in their balloons, throwing out bits of trailing web which seem to act as rudders. In their little way and in a perfectly adequate fashion they have solved aerial navigation, which still puzzles us. We admire spiders and kill only those with yellow stomachs, which are "poison." ---- But up to the present we have found the ant the most interestingly suggestive creature. He has developed and understands stirpiculture--the improvement of the race by careful breeding--which with us is as yet mere theory, and as we look down at the ant, we look up to him because the strangely active creature manages to do without sleep. We human beings drowse through thirty years of our threescore and ten, but the ant is awake and working all the time. If the ant has managed to live without sleep, if he has acquired the faculty of lifelong wakefulness, why should we not do as much in time? We take it for granted that sleep is essential, as we take everything else for granted. We used to take it for granted that the earth was flat, but we have stopped that. Sleep was at one time forced upon man and other animals. The earth in its rollings turned away from the sun once in every twenty-four hours. In the darkness of the beginning man said to himself: "If I go walking around, I shall fall into a hole, so I shall lie down and wait until the sun comes again." He did as all the animals did before him for millions of years. Since that time, man has conquered darkness. Why should he not ultimately conquer sleep? We know that thin men, nervous, highly organized, do with far less sleep than others. We know that old age requires less sleep than youth. Can we not cultivate and develop the characteristics which make sleep less necessary? Higher races of apes have abolished tails. Can't we abolish sleep? ----
