the trees and birds were unlike anything that I had ever seen upon Mars, and then through the further trees I could see that most un-Martian of all sights—an open sea, its blue waters shimmering beneath the brazen sun. As I rose to investigate further I experienced the same ridiculous catastrophe that had met my first attempt to walk under Martian conditions. The lesser attraction of this smaller planet and the reduced air pressure of its greatly rarefied atmosphere, afforded so little resistance to my earthly muscles that the ordinary exertion of the mere act of rising sent me several feet into the air and precipitated me upon my face in the soft and brilliant grass of this strange world. This experience, however, gave me some slightly increased assurance that, after all, I might indeed be in some, to me, unknown corner of Mars, and this was very possible since during my ten years’ residence upon the planet I had explored but a comparatively tiny area of its vast expanse. I arose again, laughing at my forgetfulness, and soon had mastered once more the art of attuning my earthly sinews to these changed conditions. As I walked slowly down the imperceptible slope toward the sea I could not help but note the park-like appearance of the sward and trees. The grass was as close-cropped and carpet-like as some old English lawn and the trees themselves showed evidence of careful pruning to a uniform height of about fifteen feet from the ground, so that as one turned his glance in any direction the forest had the appearance at a little distance of a vast, high-ceiled chamber. All these evidences of careful and systematic cultivation convinced me that I had been fortunate enough to make my entry into Mars on this second occasion through the domain of a civilized people and that when I should find them I would be accorded the courtesy and protection that my rank as a Prince of the house of Tardos Mors entitled me to. The trees of the forest attracted my deep admiration as I proceeded toward the sea. Their great stems, some of them fully a hundred feet in diameter, attested their prodigious height, which I could only guess at, since at no point could I penetrate their dense foliage above me to more than sixty or eighty feet. As far aloft as I could see the stems and branches and twigs were as smooth and as highly polished as the newest of American-made pianos. The wood of some of the trees was as black as ebony,
