In the pits there is no light, save that which men bring there. Without light, there cannot be photosynthesis. Without photosynthesis there cannot be the reduction of carbon dioxide, the formation of sugar, the beginning of the food chain. Ultimately, then, food is brought into the pits, generally in the form of organic debris, from hundreds of sources, many of them hundreds of miles distant; this debris is carried by the fresh-water feeds, through minute faults and fissures, and even porous rock, until it reaches the remains of the ancient seas, now sunken far beneath the surface. On and in this debris, breaking it down, are several varieties of bacteria. These bacteria are devoured by protozoons and rotifers. These, in turn, become food for various flatworms and numerous tiny segmented creatures, such as isopods, which, in turn, serve as food for small, blind, white crayfish, lelts and salamanders.

Once I felt it roll over my back, my body protected by the remains of the frame. Its skin was not rough, abrasive, like that of free-water sharks, but slick, coated with a bacterial slime. It slipped over me, not tearing me from the frame.

Termites, incidentally, are extremely important to the ecology of the forest. In their feeding they break down and destroy the branches and trunks of fallen trees. The termite "dust," thereafter, by the action of bacteria, is reduced to humus, and the humus to nitrogen and mineral materials.

"In the agricultural satellites," said Pyrrhus, "a number of crops are grown, not blood food, but crops from which, suitably processed, nourishment may be obtained. We may arrange growing seasons, temperature, soil nutriments, light and darkness, and such, as we please. Thus we may have crops all year around in any fashion desired. There are no noxious insects, or such, either, to compete for the food, as we have not allowed their entry into the areas. Only such bacteria as are beneficial are admitted."
