_28th June._--At nine this morning, we reached our moorings at the Rock, but there was still so much surf that a landing could not be attempted till mid-day, when I went with Mr Macurich in the boat, and with some difficulty contrived to spring on the Rock, after which the boat returned to the vessel for the rest of the party. While left alone on this sea-beaten Rock, on which I had landed with so much difficulty, and as I watched the waves, of which every succeeding one seemed to rise higher than the last, the idea was for a few minutes forcibly impressed on my mind, that it might, probably, be found impracticable to remove me from the Rock, and I could not avoid indulging in those unaccountable fancies which lead men to speculate with something like pleasure upon the horrors of their seemingly impending fate. These reflections were rendered more impressive by the thought that many human beings must have perished amongst those rocks. A consideration, however, of the rarity of an opportunity of landing on the Rock, and the necessary shortness of our stay, soon recalled me to my duty, and before the boat returned with a few of the workmen, I had projected some arrangements as to the first step to be taken in erecting the framework of the barrack-house. The second landing was more easily effected, as the tide had fallen, and the landing-place was more sheltered, so that we were the more emboldened to make a fair commencement of operations. It was a day of great bustle and interest, the work consisting in chalking out and marking on the Rock with paint, the sites of the Lighthouse-Tower, and the wooden barrack, and the positions for cranes, crabs, and ring-bolts for guys and other tackling, as well as ascertaining such dimensions as would enable me at once to proceed to fit up the log-house, or barrack, at our next landing. In that way, we spent four hours on the Rock, much to the annoyance of the seals and the innumerable sea-fowl, which we drove from their favourite haunts. During the whole day, the sun had great power; and the smell from the cast-away feathers and the soil of the sea-fowl was extremely disagreeable. I was amazed to find that those animals should select, as their place of repose, a rock in the Atlantic, intersected by deep gullies which are never dry, with only one pinnacle, about 5 feet in diameter, raised about 16 feet above the sea. while the greater part is only 5 feet above high water. Yet, in a crevice of this Rock, I found an egg resting on a few downy feathers, which the first wave must have infallibly washed away! After the day’s work on the Rock, we sailed for Tyree, but did not reach the workyard till next morning at nine; and a long day of bustle and hurry was spent there in preparing provisions, timber, ring-bolts, chains and all sorts of tackling for the operations connected with the erection of the barrack on the Rock. On the evening of the 30th June, I sailed for
