Monday, 7th.

The wind had shifted to the S.W. to-day, but still a heavy swell of the sea prevented the landing of materials, and the artificers were accordingly employed in shifting the crane on the building, and at low-water they were all engaged in fixing and extending the Railways towards the western creek.

Tuesday, 8th.

12 stones laid.

Mr Sheriff Hamilton visits the works.

The sea having fallen considerably, the loaded Praam-boat got to the Rock, and the artificers laid the 12 stones which had now been on board of her since the 5th. The works at the Rock were visited to-day by Mr Robert Hamilton, Sheriff of Lanark, and ex officio one of the Commissioners of the Northern Light-houses, who expressed much satisfaction at the progress of the operations.

Wednesday, 9th.

36 stones laid.

Additional supports for the Beacon landed to-day.

The number of artificers were augmented from 24 to 26, and measures were taken for leveling the necessary sites on the Rock for some additional supports for the legs or principal beams of the Beacon. These supports had been prepared in the course of the winter, but had not yet been applied, from the pressing nature of the building operations. They consisted both of iron and of timber, the former to connect the principal beams horizontally, and the latter diagonally, in order that, by every possible means, this essential part of the establishment might be preserved through the winter, and divested of the twist so expressively felt and complained of by Mr Logan, on the 30th of May. To-day 36 stones were landed and built, which finished the Nineteenth course, and brought the building to the height of about 23 feet.
