An Account of the Bell Rock Light-House / Including the Details of the Erection and Peculiar Structure of That Edifice; to Which Is Prefixed a Historical View of the Institution and Progress of the Northern Light-Houses

by Robert Stevenson

From the difficulties attending the landing on the rock, owing to the breach of sea which had for days past been around it, the artificers showed some backwardness at getting into the boats this morning; but after a little explanation this was got over. It was always observable, that for some time after any thing like danger had occurred at the Rock, the workmen became much more cautious, and on some occasions their timidity was rather troublesome. It fortunately happened, however, that, along with the writer’s assistants and the sailors, there were also some of the artificers themselves who felt no such scruples, and in this way these difficulties were the more easily surmounted. In matters where life is in danger, it becomes necessary to treat even unfounded prejudices with tenderness, as an accident, under certain circumstances, would not only have been particularly painful to those giving directions, but have proved highly detrimental to the work, especially in the early stages of its advancement.

Tender sails for Arbroath.

The wind was at south this morning, accompanied with very heavy showers of rain; and though the boats effected a landing at 12 noon; yet, during the whole tide, there was not less depth than 15 inches of water on the highest part of the site of the building, while the sea was continually ranging into it. The artificers were, therefore, employed on the higher parts of the eastern railway-track. After an hour and three-quarters work, the boats returned to the Tender, which had already cast off from her moorings, and kept plying about till they left the rock with the artificers, when she immediately sailed for Arbroath, and got into the harbour at 6 P. M. Here the artificers were employed in the work-yard for six days, until the return of spring-tides. During this interval ashore, the smiths were busily employed in giving the picks and other tools a thorough repair. Every measure was also adopted that could possibly facilitate the fitting up of the railways, without the aid of which the blocks of stone could not possibly be conveyed along the rugged surface of the rock after they were landed.

First entire course removed from the platform.

The operations at the rock, both in the preparation of the foundation of the building, and in the fitting up of the railways for landing the materials, became more and more urgent as the work advanced ashore. The first course had now been removed from the platform, and the greater part of the second was laid in its place; and, in the course of three weeks, it was also expected to be in readiness to ship for the rock, while a number of the higher courses were in a considerable state of forwardness. Some of the Aberthaw limestone having been burnt, and reduced to a state of powder, it was put into casks, while equal quantities of pozzolano and clean sharp sand were also made up in the same manner, to be used in building up the inequalities on the south east or lowest part of the margin of the foundation-pit, that by this means the water might be more speedily pumped out, and a longer period of the tide obtained for carrying on the work.

Trial of the landing apparatus.

It being apparent, from the present state of things, that we should be ready for building in the course of the next spring-tides, if the weather proved favourable, it was necessary to have all the apparatus for landing the stones at the rock in a working state. While at Arbroath, the writer had a trial made of one of the new praams or stone-lighters, by towing her into the bay of Arbroath, with a large stone upon deck, where the sloop Smeaton had been previously anchored with her gaff-boom and tackle rigged. This experiment was made in pretty rough weather, when the block of stone was lifted with the tackle in and out of the Smeaton’s hold, and again placed on the praam’s deck, as was to be done in the operation of landing at the rock. The apparatus is represented in [Plate XI.], and the trial was highly satisfactory, the tackle requiring only some trifling alterations. The Smeaton was then brought into the harbour and trimmed with ballast, consisting of pieces of granite, neatly fitted into her hold, over which a platform was laid, which completed her for the service of taking the stones from Arbroath to the Bell Rock.
