The appearance of the rock about this time is thus described: ‘Its surface was crowded with men, the two forges flaming, the one above the other, upon the beacon, while the anvils thundered with the rebounding noise of their wooden supports, and formed a curious contrast with the clamour of the surges.’ Sometimes, when the sea was smooth, the beacon had the appearance of being afloat upon the water, with a number of men supporting themselves in every variety of attitude and position; while from the upper part of this wooden house, such volumes of smoke ascended from the forges, that strangers at a distance often mistook it for a ship on fire. When working by such light at night, the rock presented a remarkable aspect to the distant shipping, the numerous lights flitting about, apparently below the surface of the water, having a curious and fanciful appearance. To the workmen themselves, the effect of extinguishing the torches was sometimes startling, and made the darkness of the night quite horrible, while the sea would assume that phosphoric appearance so familiar to the sailor, and dash upon the rock like so much liquid fire. As the work proceeded, the smiths were sometimes left on the beacon throughout the day, and the noise of their anvils was an excellent guide to the boats in foggy weather. This circumstance confirmed the engineer, as to the propriety of erecting in the lighthouse large bells, to be tolled by machinery day and night, during the continuance of foggy weather, by which the mariner may be forewarned of too near an approach to the rock. The foundation pit having assumed the appearance of a large even platform, and the tides being favourable, it was determined to lay down the first course, which consisted of a few irregular and detached stones for making up certain inequalities in the interior parts of the site of the building. Having taken the dimensions of the first or foundation stone, a model of its figure was made, and this was taken by the engineer in a fast-rowing boat to the work-yard at Arbroath: two men were immediately set to work upon one of the blocks from the Mylnefield quarry, and as the stone-cutters relieved each other, and worked without intermission, the stone was soon prepared, and sent off next day in one of the stone-lighters. On the 9th July the stone was placed in a praam-boat, decorated with colours for the occasion. Flags were also displayed upon the beacon and from the shipping in the offing. The stone was gently lowered into the water, which occupied the site of the building, amidst the cheering of all present. The stone was necessarily landed at high water, for want of a sufficient length of railway for conveying it along the rock at low water to the site of the building.
