For instance, there was one whole section, several square miles in extent apparently, that looked exactly like ferns. Another reminded me of a certain flowering plant (I can’t recall the name of it) which grows a vast number of small blossoms on a flat surface at the top. The stems are a curious whitish green. This moon tree was _exactly_ the same, only nearly a thousand times as big. The denseness of the foliage (or flowering) at the top was so compact and solid that we later found no rain could penetrate it. And for this reason the Doctor and I gave it the name of the _Umbrella Tree_. But not one single tree was there which was the same as any tree we had seen before. And there were many, many more curious growths that dimly reminded you of something, though you could not always say exactly what. [Illustration: “_We approached the bluff on whose brow the vegetation flourished_”] One odd thing that disturbed us quite a little was a strange sound. Noises of any kind, no matter how faint, we already knew could travel long distances on the Moon. As soon as we had gained the plateau on top of the bluff we heard it. It was a musical sound. And yet not the sound of a single instrument. It seemed almost as though there was a small orchestra somewhere playing very, very softly. We were by this time becoming accustomed to strange things. But I must confess that this distant hidden music upset me quite a little and so, I know, it did the Doctor. [Illustration: _The Umbrella Tree_] At the top of the bluff we rested to get our wind before we covered the last mile up to the jungle itself. It was curious how clearly marked and separated were those sections of the Moon’s landscape. And yet doubtless the smaller scale of all the geographical features of this world, so much less in bulk than our own, could partly account for that. In front of us a plateau stretched out, composed of hard sand, level and smooth as a lake, bounded in front by the jungle and to the rear of us by the cliff we had just scaled. I wondered as I looked across at the forest what scenery began on the other side of the woods and if it broke off in as sharp a change as it did here. As the most important thing to attend to first was the establishment of a water supply, Chee-Chee was asked to act as guide. The monkey set out ahead of us to follow his own tracks which he had made last night. This he had little difficulty in doing across the open plateau. But when we reached the edge of the forest it was not so easy. Much of his traveling here had been done by swinging through the trees. He always felt safer so, he said, while explaining to us how he had been guided to the water by the sense of smell.
