"But we are increasing rapidly--your sister, Hare-Up, already has four children. We are increasing rapidly and making ready for a new climb toward civilization. In time, pressure of population will compel us to spread out, and a hundred generations from now we may expect our descendants to start across the Sierras, oozing slowly along, generation by generation, over the great continent to the colonization of the East--a new Aryan drift around the world.

"But it will be slow, very slow; we have so far to climb. We fell so hopelessly far. If only one physicist or one chemist had survived! But it was not to be, and we have forgotten everything. The Chauffeur started working in iron. He made the forge which we use to this day. But he was a lazy man, and when he died he took with him all he knew of metals and machinery. What was I to know of such things? I was a classical scholar, not a chemist. The other men who survived were not educated. Only two things did the Chauffeur accomplish-the brewing of strong drink and the growing of tobacco. It was while he was drunk, once, that he killed Vesta. I firmly believe that he killed Vesta in a fit of drunken cruelty though he always maintained that she fell into the lake and was drowned.

"And, my grandsons, let me warn you against the medicine-men. They call themselves doctors, travestying what was once a noble profession, but in reality they are medicine-men, devil-devil men, and they make for superstition and darkness. They are cheats and liars. But so debased and degraded are we, that we believe their lies. They, too, will increase in numbers as we increase, and they will strive to rule us. Yet are they liars and charlatans. Look at young Cross-Eyes, posing as a doctor, selling charms against sickness, giving good hunting, exchanging promises of fair weather for good meat and skins, sending the death stick, performing a thousand abominations. Yet I say to you, that when he says he can do these things, he lies. I, Professor Smith, Professor James Howard Smith, say that he lies. I have told him so to his teeth. Why has he not sent me the death-stick? Because he knows that with me it is without avail. But you, Hare-Up, so deeply are you sunk in black superstition that did you awake this night and find the death-stick beside you, you would surely die. And you would die, not because of any virtues in the stick, but because you are a savage with the dark and clouded mind of a savage.

"The doctors must be destroyed, and all that was lost must be discovered over again. Wherefore, earnestly, I repeat unto you certain things which you must remember and tell to your children after you. You must tell them that when water is made hot by fire, there resides in it a wonderful thing called steam, which is stronger than ten thousand men and which can do all man's work for him. There are other very useful things. In the lightning flash resides a similarly strong servant of man, which was of old his slave and which some day will be his slave again.
