assailed their nostrils, an odor similar to that produced by pouring sulphuric acid on copper.
He switched on the forward searchlight, which revealed the shattered front of their craft jammed against an enormous tree-trunk. The keel rested in a forked branch, which kept them from falling. A thin column of vapor curled upward from the shattered hull, emitting the stifling odor that had greeted them when he opened the door.
"I guess we are done with flying," said Grandon, eyeing the wreck askance. "At least, we will fly no more with this airship."
"Is it so badly broken?"
"The power mechanism is destroyed. An Olban once told me that a phial of acid was placed within each mechanism in such a fashion that it would instantly destroy it if tampered with. Evidently the shock of our encounter with the tree trunk broke the phial, for the fumes are unmistakably those of acid on metal."
Grandon flashed the searchlight about them in an effort to ascertain where they were, but above, below and around them on every side they could see only branches and leaves. And such leaves! They were spatulate in shape, and a dark glossy green in color, varying between fifteen and twenty feet in length, while the stems were from eight to twelve inches thick. Each twig would have made a good sized fern tree, while the trunk against which their craft had jammed was a full fifty feet in thickness.
"Not much use to do any exploring before morning, I guess," said Grandon. "This is a giant of a tree. In what part of Reabon do these trees grow, and what do you call them?"
"There are no trees like this in Reabon," replied Vernia, "nor was I aware that there were such trees anywhere on Zarovia. Are you positive that we have been traveling due north?"
Grandon glanced at the compass. "Strange," he said. "Just a moment before we struck, the needle pointed in the direction in which we were traveling. Now it points at right angles to the keel. Something must have been broken by the grampites. I'm afraid well have to wait until the sun rises to get our bearings."
"We can at least be positive of two things. That we are not in Reabon, and that we are in some unexplored part of Zarovia."
At dawn, Grandon made his way down the tree trunk, clinging to the rough, curling bark with fingers and toes. It was a long, perilous descent, a matter of at least a thousand feet, and he guessed half an hour must have elapsed before he stood on the ground.
The forest giant under which he stood was more than a hundred feet in diameter at the base. All about him, as far as he could see, were many more like it. He noticed that all of the trees were connected by broad surface roots, and this fact, together with the total absence of spores or seeds, apprised him of the reason why these trees were, in all probability, confined to a single locality.
They must have begun and evolved on this part of the planet without developing other means of propagation than that of sending out surface roots to form new plants at some distance from the parent trees. Consequently their spread would be regulated, not only by the number of new trees they could produce in this manner, but by the character of the surrounding country as well, for any barrier such as a body of water or a stretch of barren, rocky land would effectually check their progress.
Marking his trail by slashing trees or surface roots with his knife as he passed along, Grandon started his journey of exploration. He felt like a pygmy, as he walked beneath those mighty spires of wood, treading matted, molding leaves that were nearly as long as the airship, and climbing over surface roots so thick that often he could not see over them. After he had traveled thus for more than half an hour he saw a number of tall, conical mounds ahead of him, and judged from the regularity of their construction, that they housed human beings. As he
