Note 92a — Chapter III · : THE BUILDING OF THE BELL ROCK

The particular event which concentrated Mr. Stevenson’s attention on the problem of the Bell Rock was the memorable gale of December 1799, when, among many other vessels, H.M.S. York, a seventy-four-gun ship, went down with all hands on board. Shortly after this disaster Mr. Stevenson made a careful survey, and prepared his models for a stone tower, the idea of which was at first received with pretty general scepticism, Smeaton’s Eddystone tower could not be cited as affording a parallel, for there the rock is not submerged even at high-water, while the problem of the Bell Rock was to build a tower of masonry on a sunken reef far distant from land, covered at every tide to a depth of twelve feet or more, and having thirty-two fathoms’ depth of water within a mile of its eastern edge.
