Having landed this morning at 10, the work was continued during four hours, when 14 stones were laid; but its regular progress had now to be stopped for a time, owing to the want of stones from the work-yard, where some blocks of granite were waited for from the quarries. In the afternoon the Smeaton arrived with a few hearting or interior stones of the course in hand; but the wind having been for some days past in the N.E., accompanied with a considerable swell of sea, it was not found practicable to make a landing, and the praam-boat, after having been loaded, was made fast to her moorings: consequently no landing was made on the Rock with the night tide. [Sidenote: Monday, 12th.] [Sidenote: Building level with the higher parts of the Rock.] The wind being still at N.E., the swell was so great that the boats landed with much difficulty on the Rock this morning at half-past 11 o’clock, but could only remain for an hour and a half, owing to the heavy sea which ran upon it. This tide was employed in completing the boring of the trenail-holes, and in securing the stones which had been laid. The cranes were also raised from the second to the third course, which being 18 inches in thickness, the artificers who worked them now stood nearly on a level with the highest parts of the Rock. [Sidenote: Tuesday, 13th.] [Sidenote: 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. [Sidenote: Two Stones loosened but are again secured. The vessels slip their moorings.]
