From observations often made by the writer, in so far as such can be ascertained, it appears that no wave in the open seas, in an unbroken state, rises more than from seven to nine feet above the general surface of the ocean. The Bell Rock Lighthouse may therefore now be considered at from eight to ten feet above the height of the waves; and, although the sprays and heavy seas have often been observed, in the present state of the building, to rise to the height of fifty feet, and fall with a tremendous noise on the beacon-house, yet such seas were not likely to make any impression on a mass of solid masonry, containing about 1400 tons,

The whole of the artificers left the rock at mid-day, when the tender made sail for Arbroath, which she reached about six p.m. The vessel being decorated with colours, and having fired a salute of three guns on approaching the harbour, the workyard artificers, with a multitude of people, assembled at the harbour, when mutual cheering and congratulations took place between those afloat and those on the quays. The tender had now, with little exception, been six months on the station at the Bell Rock, and during the last four months few of the squad of builders had been ashore. In particular, Mr. Peter Logan, the foreman, and Mr. Robert Selkirk, principal builder, had never once left the rock. The artificers, having made good wages during their stay, like seamen upon a return voyage, were extremely happy, and spent the evening with much innocent mirth and jollity.
In reflecting upon the state of the matters at the Bell Rock during the working months, when the writer was much with the artificers, nothing can equal the happy manner in which these excellent workmen spent their time. They always went from Arbroath to their arduous task cheering and they generally returned in the same hearty state. While at the rock, between the tides, they amused themselves in reading, fishing, music, playing cards, draughts, etc., or in sporting with one another. In the workyard at Arbroath the young men were almost, without exception, employed in the evening at school, in writing and arithmetic, and not a few were learning architectural drawing, for which they had every convenience and facility, and were, in a very obliging manner, assisted in their studies by Mr. David Logan, clerk of the works. It therefore affords the most pleasing reflections to look back upon the pursuits of about sixty individuals who for years conducted themselves, on all occasions, in a sober and rational manner.
IV--OPERATIONS OF 1810
[Thursday, 10th May]
The wind had shifted to-day to W.N.W., when the writer, with considerable difficulty, was enabled to land upon the rock for the first time this season, at ten a.m. Upon examining the state of the building, and apparatus in general, he had the satisfaction to find everything in good order. The mortar in all the joints was perfectly entire. The building, now thirty feet in height, was thickly coated with fuci to the height of about fifteen feet, calculating from the rock: on the eastern side, indeed, the growth of seaweed was observable to the full height of thirty feet, and even on the top or upper bed of the last-laid course, especially towards the eastern side, it had germinated, so as to render walking upon it somewhat difficult.
The beacon-house was in a perfectly sound state, and apparently just as it had been left in the month of November. But the tides being neap, the lower parts, particularly where the beams rested on the rock, could not now be seen. The floor of the mortar gallery having been already laid down by Mr. Watt and his men on a former visit, was merely soaked with the sprays; but the joisting-beams which supported it had, in the course of the winter, been covered with a fine downy conferva produced by the range of the sea. They were also a good deal whitened with the mute of the cormorant and other sea-fowls, which had roosted upon the beacon in winter.
