He explained that the eggs had just been placed there; but, like all green Martian eggs, they would grow during the five-year period of incubation until they obtained the size of those I had seen hatching on the day of my arrival on Barsoom. This was indeed an interesting piece of information, for it had always seemed remarkable to me that the green Martian women, large as they were, could bring forth such enormous eggs as I had seen the four-foot infants emerging from. As a matter of fact, the new-laid egg is but little larger than an ordinary goose egg, and as it does not commence to grow until subjected to the light of the sun the chieftains have little difficulty in transporting several hundreds of them at one time from the storage vaults to the incubators.

I was engaged in changing my riding cloths from one of my thoats to the other, for I divided the day’s work between them, when Zad approached me, and without a word struck my animal a terrific blow with his long-sword.
