I shall never forget, though, Perry's first experiments with gunpowder. When he got it perfected he was so proud you couldn't hold him. "Look at it!" he cried, as he exhibited a quantity of it for my inspection. "Feel of it. Smell of it. Taste it. This is the proudest day of my life, David. This is the first step toward civilization, and a long one."

Well, it certainly did seem to have all the physical attributes of gunpowder; but it must have lacked some of its spirit, for it wouldn't burn. Outside of that it was pretty good gunpowder. Perry was crushed; but he kept on experimenting, and after a while he produced an article that would kill anybody.

And then there was the beginning of the battle fleet. Perry and I built the first ship on the shores of a nameless sea. It was a flat-bottom contraption that bore a startling resemblance to an enormous coffin. Perry is a scientist. He had never built a ship and knew nothing about ship design; but he contended that because he was a scientist, and therefore a highly intelligent man, he was fitted to tackle the problem from a scientific bases. We built it on rollers, and when it was finished we started it down the beach toward the water. It sailed out magnificently for a couple of hundred feet and then turned over. Once again Perry was crushed; but he kept doggedly at it, and eventually we achieved a navy of sailing ships that permitted us to dominate the seas of our little corner of this great, mysterious inner world, and spread civilization and sudden death to an extent that amazed the natives. When I left Sari on this expedition I am about to tell you of, Perry was trying to perfect poison gas. He claimed that it would do even more to bring civilization to the Old Stone Age.
