Presently, relieving each other frequently, we completed the second cut, and after that the bo'sun set us to saw a block about twelve inches deep from the remaining portion of the topmast. From this, when we had cut it, he proceeded to hew wedges with the hatchet. Then he notched the end of the fifteen-foot log, and into the notch he drove the wedges, and so, towards evening, as much, maybe, by good luck as good management, he had divided the log into two halves--the split running very fairly down the center. Now, perceiving how that it drew near to sundown, he bade the men haste and gather weed and carry it across to our camp; but one he sent along the shore to make a search for shell-fish among the weed; yet he himself ceased not to work at the divided log, and kept me with him as helper. Thus, within the next hour, we had a length, maybe some four inches in diameter, split off the whole length of one of the halves, and with this he was very well content; though it seemed but a very little result for so much labor. By this time the dusk was upon us, and the men, having made an end of weed carrying, were returned to us, and stood about, waiting for the bo'sun to go into camp. At this moment, the man the bo'sun had sent to gather shellfish, returned, and he had a great crab upon his spear, which he had spitted through the belly. This creature could not have been less than a foot across the back, and had a very formidable appearance; yet it proved to be a most tasty matter for our supper, when it had been placed for a while in boiling water. Now so soon as this man was returned, we made at once for the camp, carrying with us the piece of timber which we had hewn from the topmast. By this time it was quite dusk, and very strange amid the great fungi as we struck across the upper edge of the valley to the opposite beach. Particularly, I noticed that the hateful, mouldy odor of these monstrous vegetables was more offensive than I had found it to be in the daytime; though this may be because I used my nose the more, in that I could not use my eyes to any great extent.
