The wind being west to-day, the weather was very favourable for the operations at the rock, and during the morning and evening tides, with the aid of torch-light, the masons had seven hours’ work upon the site of the building. The smiths and joiners, who landed at half-past 6 A. M., did not leave the rock till a quarter past 11 P. M., having been at work, with little intermission, for sixteen hours and three quarters. When the water left the rock, they were employed at the lower parts of the beacon, and as the tide rose or fell, they shifted the place of their operations. From these exertions, the fixing and securing of the beacon made rapid advancement, as the men were now landed in the morning, and remained throughout the day. But, as a sudden change of weather might have prevented their being taken off at the proper time of tide, a quantity of bread and water was always kept on the Beacon. [Sidenote: Sunday 4th.] The wind was southerly during the fore part of the day, and towards evening it became quite calm. The boats landed the artificers this morning at a quarter before 7 o’clock; when the masons had three and a half hours’ work at the foundation of the building, but the spring-tides were now taking off; the best of them having unfortunately been lost during the late gale. The smiths and joiners, however, continued their operations throughout the whole of the day, and did not leave the rock till half-past 12 at night. During this period of working at the Beacon all the day, and often a great part of the night, the writer was much on board of the Tender; but, while the masons could work on the rock, and frequently also while it was covered by the tide, he remained on the Beacon; especially during the night, as he made a point of being on the rock to the latest hour, and was generally the last person who stepped into the boat. He had laid this down as part of his plan of procedure; and in this way had acquired, in the course of the first season, a pretty complete knowledge and experience of what could actually be done at the Bell Rock, under all circumstances of the weather. By this means also his assistants, and the artificers and mariners, got into a systematic habit of proceeding at the commencement of the work, which, it is believed, continued throughout the whole of the operations. [Sidenote: Beacon works finished for the season.]
