[Sidenote: 17 stones are laid. The Building operations completed for the season.] The Smeaton not having been made fast to the buoy, had, with the ebb-tide, drifted to leeward, a considerable way eastward of the Rock, and could not, till the return of the flood-tide, be worked up to her moorings, so that the present tide was lost, notwithstanding all exertions which had been made both ashore and afloat with this cargo. The artificers landed at 6 A. M., but as no materials could be got upon the Rock this morning, they were employed in boring trenail holes, and in various other operations, and after four hours’ work they returned on board the Tender. When the Smeaton got up to her moorings, the landing-master’s crew immediately began to unload her. There being too much wind for towing the praams in the usual way, they were warped to the Rock, in the most laborious manner, by their windlasses, with successive grapplings and hawsers laid out for this purpose. At 6 P. M., the artificers landed, and continued at work till half-past 10, when the remaining seventeen stones were laid, which completed the Third entire course, or Fourth of the Light-house, with which the building operations were closed for this season. [Sidenote: Summary of the Building operations at the Rock.] The building, being now on a level with the highest part of the margin of the foundation-pit, or about 5 feet 6 inches above the lower bed of the foundation-stone, is computed to contain about 388 tons of stone; consisting of 400 blocks, connected with 738 oaken trenails, and 1215 pairs of oaken wedges. The number of hours of low-water work upon the Rock this season, amounted to about 265, of which number only 80 were employed in building. It was further highly satisfactory to find, that the apparatus, both in the work-yard at Arbroath, and also the craft and building apparatus at the Rock, were found to answer every purpose much beyond expectation. The operations of this season, therefore, afforded the most flattering prospects of the practicability of completing the solid part, or first 30 feet of the building, in the course of another year. [Sidenote: Sunday, 25th.] [Sidenote: Shipping obliged to run for Arbroath.] Owing to very heavy gales of wind from a north-eastern direction, the Sir Joseph Banks Tender, the Sloop Smeaton, and Light-house Yacht, were, on the 22d, obliged to slip their moorings, and proceed with all hands for Arbroath. The Tender and the Smeaton again returned to their stations at the Bell Rock on the 25th; the former to attend the mill-wrights, joiners, and smiths, while they completed certain operations connected with the Railways, and Beacon-house, that everything might be left in as secure a state as possible for the winter months; the crew of the Smeaton being at the same time occupied in lifting the several sets of moorings, building-cranes, and other apparatus connected with the works, which she carried to Arbroath.
