Now in the early morning, when we had gone for the fuel, we had kept to the upper skirt of the valley where the rock of the nearer hill came down into the spongy ground, but now we struck right down into the middle part of the vale, making a way amid the mighty fungi to the pit-like opening that filled the bottom of the valley. Now though the ground was very soft, there was in it so much of springiness that it left no trace of our steps after we had gone on a little way, none, that is, save that in odd places, a wet patch followed upon our treading. Then, when we got ourselves near to the pit, the ground became softer, so that our feet sank into it, and left very real impressions; and here we found tracks most curious and bewildering; for amid the slush that edged the pit--which I would mention here had less the look of a pit now that I had come near to it--were multitudes of markings which I can liken to nothing so much as the tracks of mighty slugs amid the mud, only that they were not altogether like to that of slugs; for there were other markings such as might have been made by bunches of eels cast down and picked up continually, at least, this is what they suggested to me, and I do but put it down as such. Apart from the markings which I have mentioned, there was everywhere a deal of slime, and this we traced all over the valley among the great toadstool plants; but, beyond that which I have already remarked, we found nothing. Nay, but I was near to forgetting, we found a quantity of this thin slime upon those fungi which filled the end of the little valley nearest to our encampment, and here also we discovered many of them fresh broken or uprooted, and there was the same mark of the beast upon them all, and now I remember the dull thuds that I had heard in the night, and made little doubt but that the creatures had climbed the great toadstools so that they might spy us out; and it may be that many climbed upon one, so that their weight broke the fungi, or uprooted them. At least, so the thought came to me. And so we made an end of our search, and after that, the bo'sun set each one of us to work. But first he had us all back to the beach to give a hand to turn over the boat, so that he might get to the damaged part. Now, having the bottom of the boat full to his view, he made discovery that there was other damage beside that of the burst plank; for the bottom plank of all had come away from the keel, which seemed to us a very serious matter; though it did not show when the boat was upon her bilges. Yet the bo'sun assured us that he had no doubts but that she could be made seaworthy, though it would take a greater while than hitherto he had thought needful.
