 juries, similarly do we enjoy the physical pleasures of the rykors. When your body becomes fatigued you are comparatively useless; it is sick, you are sick; if it is killed, you die. You are the slave of a mass of stupid flesh and bone and blood. There is nothing more wonderful about your carcass than there is about the carcass of a banth. It is only your brain that makes you superior to the banth, but your brain is bound by the limitations of your body. Not so, ours. With us brain is everything. Ninety per centum of our volume is brain. We have only the simplest of vital organs and they are very small for they do not have to assist in the support of a complicated system of nerves, muscles, flesh and bone. We have no lungs, for we do not require air. Far below the levels to which we can take the rykors is a vast network of burrows where the real life of the kaldane is lived. There the air-breathing rykor would perish as you would perish. There we have stored vast quantities of food in hermetically sealed chambers. It will last forever. Far beneath the surface is water that will flow for countless ages after the surface water is exhausted. We are preparing for the time we know must come—the time when the last vestige of the Barsoomian atmosphere is spent—when the waters and the food are gone. For this purpose were we created, that there might not perish from the planet Nature's divinest creation—the perfect brain."
