Experience great difficulty in landing.

The wind being still at N.E., accompanied with a heavy breach on the Rock, no attempt would have been made to land to-day, had not the writer felt a more than ordinary desire to examine the state of the work, from the manner in which the sea broke upon the building. In accomplishing this about noon, the boats were frequently put back, but were at length successful, when it was found that the force of the sea had raised two of the stones exposed to its immediate wash, which, in the unfinished state of the course, formed an abrupt face to the waves. These two stones were lifted perpendicularly off their beds, the one to the height of 6, the other of 10 inches; but they were fortunately still held by the trenails, and supported as if on stilts. Had this not been timeously observed, the probability is, that the operation of another tide might have swept them into deep water, which would have been attended with much additional hazard, by delaying the work in its present state, at so advanced a period of the season.

Two Stones loosened but are again secured. The vessels slip their moorings.

The trenails of these stones having been drawn or bored out, the stones were laid a second time, when every precaution was taken to secure the mortar, by stuffing bagging-cloth round the joints, and loading them with bars of iron. The guy-ropes of the cranes were also tightened, and every thing put in as complete a state of security as circumstances would admit. At 1 P. M. the boats again returned to the Tender, which now rode so heavily at her moorings that it was found necessary to get her under way, when she sailed for Arbroath with the artificers. The Smeaton also slipped her moorings; but instructions were previously given to Mr Pool, to keep as close as possible to the loaded praam-boat, still riding at her moorings, that, in the event of her breaking adrift, he might be at hand to take her in tow. In the evening, however, the weather moderated considerably, and, after landing the masons at Arbroath, to remain till the return of spring-tides, the Tender returned to her station at the Rock, with the workmen employed at the Beacon-house and Railways.

Saturday, 17th.

10 Stones are laid. The praam-boats ride out the gale.

The Light-house Yacht having to-day returned from the Northern Light-houses, she transported the builders from Arbroath to the Rock, and supplied the Floating-light and Tender with provisions and necessaries. By this means, the latter vessel was enabled to remain at her moorings during the present neap-tides, by which the operations on the higher parts of the Beacon made great progress. The writer also embarked this morning in the Light-house Yacht, and having hailed the Floating-light at noon, found that she had rode out the late gales with great ease. At 3 o’clock P. M. the Yacht was made fast to a set of moorings which had been laid down for her early in the season; and at 5, thirty artificers landed, when 10 stones were laid in two hours and a quarter. Notwithstanding the heavy seas which had run upon the Rock since the completion of the Second course, every thing was found in good order. The stones of the course in hand were all in their respective places, and the joints were full of mortar. The cranes also stood quite firm, with their guys and tackling. It was no less satisfactory to find that the loaded praam rode at her moorings in perfect safety, without having apparently shipped any sea during the gale.

Sunday, 18th.

31 Stones laid in 6¼ hours.

The artificers landed this morning at 5 o’clock, and continued at work till a quarter past 8. The railways being now in a pretty complete state, and a further supply of stones having been brought to the Rock, the landing-master got 21 blocks conveyed from the eastern wharf to the building. In the same manner, with the evening tide, 10 stones were landed, and the work continued from half-past 5 to half-past 8, having had six hours’ and a quarter’s work to-day, during which no fewer than 31 stones were laid.
