The wind was at NE. this morning, and though there were only light airs, yet there was a pretty heavy swell coming ashore upon the rock. The boats landed at half-past 7 o’clock A. M., at the creek on the southern side of the rock, marked Port Hamilton in Plate VI., which to-day was found to be the most accessible landing-place. But as one of the boats was in the act of entering this creek, the seaman at the bow oar, who had just entered the service, having inadvertently expressed some fear, from a heavy sea which came rolling towards the boat, and one of the artificers having at the same time looked round and missed a stroke with his oar, such a preponderance was thus given to the rowers upon the opposite side, that when the wave struck the boat, it threw her upon a ledge of shelving rocks, where the water left her, and she having _kanted_ to seaward, the next wave completely filled her with water. After making considerable efforts, the boat was again got afloat in the proper track of the creek, so that we landed without any other accident than a complete ducking. This accident caused us to lose some time; but, as the boats could not conveniently leave the rock till flood-tide, and there being no possibility of getting a shift of clothes, the artificers began with all speed to work, so as to bring themselves into heat, while the writer, and his assistants, kept as much as possible in motion. Having remained more than an hour upon the rock, the boats left it at half-past 9; and after getting on board, the writer recommended to the artificers, as the best mode of getting into a state of comfort, to strip off their wet clothes, and go to bed for an hour or two. No farther inconveniency was felt, and no one seemed to complain of the affection called “catching cold.” It was a standing order in the landing department, that every man should use his greatest exertions, in giving the boats sufficient force or velocity to preserve their steerage-way in entering the respective creeks at the rock, that the contending seas might not have the command of the boat at places where the free use of the oars could not be had, on account of the surrounding rocks. The late accident, accordingly, put all hands more upon their guard, as such an occurrence might have proved fatal to all on board, under a very slight change of circumstances.
