186 THE CRATER; carried the best glass of the Rancocus with him, in all his excursions, not knowing at what moment Providence might bring a vessel in sight, and he had it now slung from his shoulders. With this glass, therefore, was every part of the visible surface of the island swept, in anxious and almost alarmed search for the abodes of inhabitants. No thing of this sort, however, could be discovered. The island was unquestionably without a human being, our young man alone excepted. Nor could he see any trace of beast, reptile, or of any animal but birds. Creatures gifted with wings had been able to reach that little para dise ; but to all others, since it first arose from the sea, had it probably beett unapproached, if not unapproachable, until that day. It appeared to be the very Elysium of Birds! Mark next examined the peak itself. There was a vast deposit of very ancient guano on it, the washings of which for ages, had doubtless largely contributed to the great fertility of the plain below. A stream of more size than one would expect to find on so small an island, meandered through the plain, and could be traced to a very copious spring that burst from the earth at the base of the peak. Ample as this spring was, however, it could never of itself have supplied the water of the brook, or rivulet, which received the contributions of some fifty other springs, that reached it in rills, as it wound its way down the gently inclined plane of the island. At one point, about two leagues from the Peak, there was actually a little lake visi ble, and Mark could even trace its outlet, winding its way beyond it. He supposed that the surplus tumbled into the sea in a cascade. It will readily be imagined that our young man turned his glass to the northward, in search of the group he had left that morning, with a most lively interest. It was easy enough to see it from the great elevation at which he was now placed. There it lay, stretched far and wide, extend ing nearly a degree of latitude, north and south, and an other of longitude, east and west, most truly resembling a vast dark-looking map, spread upon the face of the waters for his special examination. It reminded Mark of the moon, with its ragged outlines of imaginary continents, as
