parts would then exert their lateral pressure against the walls; and, therefore, as a security against this, it became necessary that the circle of the enclosing walls should be bound together, and the building, as it were, _hooped_.’ Thus assiduously did Smeaton urge forward the work, yet without neglecting any of the necessary precautions for its safety. By the 10th of October he had nearly completed all the necessary arrangements for establishing a light and light-keepers at the Eddystone during the same winter, when he received an unexpected and painful refusal from the Corporation of Trinity-House, to the effect that ‘on reading the Acts of Parliament, the application from the merchants and owners of ships, and Winstanley’s narrative of the first lighthouse erected there, they are of opinion that a light cannot be exhibited on the Eddystone Rock till the lighthouse is re-built.’ Smeaton employed the winter of 1758-9 in London, preparing everything for the final work at the Eddystone the ensuing season. He formed and made out designs for the iron rails of the balcony, the cast iron, the wrought iron, and the copper-works of the lantern, &c. There was a violent storm on the 9th of March, 1759, which it was supposed might have damaged the unfinished lighthouse, as it had done very great damage to the ships and houses at Plymouth. As soon as it was possible to effect a landing the works were visited and a report sent to Smeaton. From this he found, with pleasure, that not only the solid but the hollow work remained perfectly sound and firm; all the mortar having become quite hard, and every part of the work just as it was left by the workmen in October. The commencement of the work for the next and last season, took place on the 5th of July. On the 21st of the same month the second floor was finished, and by the 29th the fortieth course of stone was laid down, and the third floor finished.
