And now, he, in turn, called my attention to the place where the huge fungi had come to a stop in their growing, and I saw that in the center of the valley there was a great circular opening in the earth, like to the mouth of a prodigious pit, and it appeared to be filled to within a few feet of the mouth with water, over which spread a brown and horrid scum. Now, as may be supposed, I stared with some intentness at this; for it had the look of having been made with labor, being very symmetrical, yet I could not conceive but that I was deluded by the distance, and that it would have a rougher appearance when viewed from a nearer standpoint. From contemplating this, I looked down upon the little bay in which our boat floated. Job was sitting in the stern, sculling gently with the steering oar and watching us. At that, I waved my hand to him in friendly fashion, and he waved back, and then, even as I looked, I saw something in the water under the boat--something dark colored that was all of a-move. The boat appeared to be floating over it as over a mass of sunk weed, and then I saw that, whatever it was, it was rising to the surface. At this a sudden horror came over me, and I clutched the bo'sun by the arm, and pointed, crying out that there was something under the boat. Now the bo'sun, so soon as he saw the thing, ran forward to the brow of the hill and, placing his hands to his mouth after the fashion of a trumpet, sang out to the boy to bring the boat to the shore and make fast the painter to a large piece of rock. At the bo'sun's hail, the lad called out "I, I," and, standing up, gave a sweep with his oar that brought the boat's head round towards the beach. Fortunately for him he was no more than some thirty yards from the shore at this time, else he had never come to it in this life; for the next moment the moving brown mass beneath the boat shot out a great tentacle and the oar was torn out of Job's hands with such power as to throw him right over on to the starboard gunnel of the boat. The oar itself was drawn down out of sight, and for the minute the boat was left untouched. Now the bo'sun cried out to the boy to take another oar, and get ashore while still he had chance, and at that we all called out various things, one advising one thing, and another recommending some other; yet our advice was vain, for the boy moved not, at which some cried out that he was stunned. I looked now to where the brown thing had been, for the boat had moved a few fathoms from the spot, having got some way upon her before the oar was snatched, and thus I discovered that the monster had disappeared, having, I conceived, sunk again into the depths from which it had risen; yet it might re-appear at any moment, and in that case the boy would be taken before our eyes.
