"Did I not tell you that we of the ruling class owned all the land, all the forest, everything? Any food-getter who would not get food for us, him we punished or compelled to starve to death. And very few did that. They preferred to get food for us, and make clothes for us, and prepare and administer to us a thousand—a mussel-shell, Hoo-Hoo—a thousand satisfactions and delights. And I was Professor Smith in those days—Professor James Howard Smith. And my lecture courses were very popular—that is, very many of the young men and women liked to hear me talk about the books other men had written.

"And I was very happy, and I had beautiful things to eat. And my hands were soft, because I did no work with them, and my body was clean all over and dressed in the softest garments—
"He surveyed his mangy goat-skin with disgust.

"We did not wear such things in those days. Even the slaves had better garments. And we were most clean. We washed our faces and hands often every day. You boys never wash unless you fall into the water or go swimming."

"Neither do you Granzer," Hoo-Hoo retorted.

"I know, I know, I am a filthy old man, but times have changed. Nobody washes these days, there are no conveniences. It is sixty years since I have seen a piece of soap.

"You do not know what soap is, and I shall not tell you, for I am telling the story of the Scarlet Death. You know what sickness is. We called it a disease. Very many of the diseases came from what we called germs. Remember that word—germs. A germ is a very small thing. It is like a woodtick, such as you find on the dogs in the spring of the year when they run in the forest. Only the germ is very small. It is so small that you cannot see it—"

Hoo-Hoo began to laugh.

"You're a queer un, Granser, talking about things you can't see. If you can't see 'em, how do you know they are? That's what I want to know. How do you know anything you can't see?"
"A good question, a very good question, Hoo-Hoo. But we did see—some of them. We had what we called microscopes and ultramicroscopes, and we put them to our eyes and looked through them, so that we saw things larger than they really were, and many things we could not see without the microscopes at all. Our best ultramicroscopes could make a germ look forty thousand times larger. A mussel-shell is a thousand fingers like Edwin's. Take forty mussel-shells, and by as many times larger was the germ when we looked at it through a microscope. And after that, we had other ways, by using what we called moving pictures, of making the forty-thousand-times germ many, many thousand times larger still. And thus we saw all these things which our eyes of themselves could not see. Take a grain of sand. Break it into ten pieces. Take one piece and break it into ten. Break one of those pieces into ten, and one of those into ten, and one of those into ten, and one of those into ten, and do it all day, and maybe, by sunset, you will have a piece as small as one of the germs." The boys were openly incredulous. Hare-Lip sniffed and sneered and Hoo-Hoo snickered, until Edwin nudged them to be silent.

The incubators are built in remote fastnesses, where there is little or no likelihood of their being discovered by other tribes. The result of such a catastrophe would mean no children in the community for another five years. I was later to witness the results of the discovery of an alien incubator.
The community of which the green Martians with whom my lot was cast formed a part was composed of some thirty thousand souls. They roamed an enormous tract of arid and semi-arid land between forty and eighty degrees south latitude, and bounded on the east and west by two large fertile tracts. Their headquarters lay in the southwest corner of this district, near the crossing of two of the so-called Martian canals.

As the incubator had been placed far north of their own territory in a supposedly uninhabited and unfrequented area, we had before us a tremendous journey, concerning which I, of course, knew nothing.

After our return to the dead city I passed several days in comparative idleness. On the day following our return all the warriors had ridden forth early in the morning and had not returned until just before darkness fell. As I later learned, they had been to the subterranean vaults in which the eggs were kept and had transported them to the incubator, which they had then walled up for another five years, and which, in all probability, would not be visited again during that period.
