The Patriot arrived at the Rock this morning, with her first cargo of building materials for the season, consisting of 42 stones, together with a supply of pozzolano, lime, sand, wedges, trenails, and 8 stone joggles. The Smeaton was completely discharged of her cargo, and sailed again at 2 P. M., when the writer took his passage with her to Arbroath.

Arrangements for conduct of the work, and safety of the Beacon.

The weather continued moderate at the Rock, with the wind at west, and 18 stones of the Patriot’s cargo were landed and built to-day. The Accounts connected with the Light-house service were collected at this period, being paid at the terms of Whitsunday and Martinmas. The writer at the same time arranged some matters more fully in the work-yard, connected with the loading of the materials at Arbroath. In particular, Mr David Logan, clerk of works, was held responsible for providing every thing contained in the Requisition of the foreman-builder; while Mr Kennedy, engineer’s clerk, was answerable for the other parts of the respective Requisitions from the Tender and Beacon, and for the dispatch given in the loading and sailing of the vessels. The masters of the stone-vessels were accordingly directed, on their arrival by night or day, to deliver all letters at the office. In the same manner, before leaving the Rock, Regulations for the proper conduct of the works there, were also instituted; where his assistants were also held responsible for the duties of their several departments; Mr Peter Logan, for the execution of the masonry; Mr Francis Watt, for the good condition of the Beacon-house, Railways, and Machinery; Captain Wilson, for the state of the Praams and other boats employed in the landing of materials, and for the safety of the stones and building-materials in transporting them from the ship’s hold till they were placed upon the waggons on the Rock. The steward, Mr John Peters, was answerable for making the necessary Requisitions for a sufficient stock of provisions, water and fuel; while Captain Taylor, master of the Tender, was to see a proper stock of these articles landed and kept in store upon the Rock. From the hazardous situation of the Beacon-house with regard to fire, being composed wholly of timber, there was no small risk from accident; and on this account, one of the most steady of the artificers was appointed to see that the fire of the cooking-house, and the lights in general, were carefully extinguished at stated hours.

Friday, 25th.

The weather continued to be extremely fine, with the wind at west, and the barometer standing about 30 inches. The landing operations proceeded briskly, so that the building was to-day ready for the Door-lintel.

Saturday, 26th.

Balance-crane shaft is broken.

The door-lintel being of large dimensions, equal to about a ton and a half in weight, and considerably heavier than any of the other stones of this course, in raising it with the balance-crane, sufficient attention had not been paid to increase the balance-weight proportionally, and an unequal strain being then brought upon the opposite arms of the crane, the upright shaft yielded, and broke at one of the joints; fortunately no person was hurt, though a stop was put to the work for the present. This unlucky accident happened about 4 in the afternoon, when the Patriot, then at her moorings, discharging a cargo of stones, was immediately dispatched to Arbroath with the broken shaft, where she arrived about 2 o’clock on Sunday morning. The writer was at this early hour rather alarmed, by Captain Macdonald knocking at his bed-room door, and calling out in a hollow tone, “that the Balance-crane had given way.” An express was immediately sent for Mr James Dove, who, only two days prior to the accident, had left the Bell Rock, and was in the neighbourhood of Arbroath, and when the messenger reached him, he was preparing to go with his friends to the church of his native parish.
