During the month of February, the weather continued to be extremely boisterous, and it was not without considerable difficulty that the Floating-light could be visited at the stated periods; while two unsuccessful attempts were made, on the 1st and 20th, to land at the Bell Rock. [Sidenote: Progress of the Works at Arbroath, and exertions made at the Quarries.] In the work-yard, the preparation of the several courses of the building was going progressively forward. The Ninth course was now finished, and part of the Tenth laid upon the platform. At Mylnefield Quarry, the operations were at a stand; for in winter, as formerly mentioned, no work is done here, owing to the liability of the stones to split in frosty weather, especially when newly taken from the quarry, the laminæ of the strata being then charged with moisture. But, as granite imbibes water very slowly, and is not liable to those changes, every exertion continued to be made at the quarries of Aberdeenshire, that, if possible, the outside casing of granite might be carried to the height of 30 feet, or to the top of the solid part of the building, instead of 16 feet, or to high-water mark, as had been latterly intended. The stone-agent at Aberdeen, accordingly, had a person traversing the numerous quarries in that neighbourhood, while one of the foremen from the work-yard at Arbroath, was similarly employed, during the winter months, at Peterhead; and whenever a stone was found answerable to the Light-house moulds, it was immediately purchased, and laid aside for the use of the Bell Rock. [Sidenote: 1809, February.] [Sidenote: Employment of Shipping.] The sloops Smeaton and Alexander made several trips to the North, and also to Mylnefield, near Dundee, for stones which had been quarried in the course of the summer months, and were in no danger from the frost; but owing to the difficult nature of the navigation of the Tay in winter, these voyages were frequently attended with considerable danger. On the last trip which the Smeaton made to this quarry, she had a very narrow escape, and lost both her boat and an anchor; but the hazardous state of the vessel and all on board, will be better understood by the following very distinct and explicit letter or journal from Mr Thomas Calder, commander of the Light-house Yacht, who, on this occasion, was acting master on board of the Smeaton. [Sidenote: Captain Calder’s account of a trip to the Tay.] _“Arbroath, 25th February 1809._ “Mr STEVENSON. “Sir,--At 3 o’clock P. M., on the 21st inst., I got under way from the South Ferry Roads for Mylnefield quarry, wind at West. At 7 were about a mile from the quarry pierhead. Light airs of wind. Got beset amongst ice, and brought up with the small bower-anchor. At midnight, all hands employed hanging fenders over the bows and sides, to save the vessel from getting cut with the ice.
