be shipped for the Rock, even if there had been no other considerations leading to the same conclusion. But in addition to all this, I could not fail to perceive that Hynish was the only place for the permanent station of the vessel attending on the future Lighthouse; and that on that account alone the construction of a Harbour there was unavoidable. That the arrangement, by which the future station for the Tender was used as the workyard for the operations, was the most judicious that could have been adopted, was fully proved by my subsequent experience of the advantage of assembling all our materials and all our force at a point as near to the Rock as possible, so that we might be at all times ready to supply defects or omissions, and take advantage of every favourable change of the sea or sky. In the middle of March the _Regent_ conveyed from Aberdeen a detachment of twenty-nine masons and quarriers and five smiths, and the foreman of the workyard, who, together with the men already at Hynish and the native labourers, were to be employed during the season of 1839, in the various departments of the work. On their arrival the men were separated into two small bands, of which the one, consisting of six masons, twelve quarriers, one smith and a foreman, was stationed at North Bay in Mull, where the new quarries were to be opened; while the other had its head quarters at Hynish, and, when not engaged in the work on the Rock itself, was subdivided into smaller parties, varying in number with the nature of the particular operations in which the men were occupied. ~Granite quarries in Mull.~ On the afternoon of the _19th April_ I sailed from Greenock in the _Regent_, for North Bay in Mull, where the quarries were to be opened. We had on board the whole materials of the new Barrack, which was to supply the place of that which had been destroyed in the preceding month of November; and we had also a party of carpenters who came to fit up the Barrack in a temporary manner at North Bay, as a residence for the masons who were to be engaged in preparing more permanent dwellings for the quarriers and in forming a landing-wharf for the shipment of the stones for Tyree. It was not till the 25th, after a tedious passage of six days, that we anchored at North Bay; and next morning we had the satisfaction of seeing the steamer, the _Skerryvore_ (by which name she was specially set apart for the service of the works), arrive in the Bay with a party of masons and quarriers, who had been appointed to meet us in order to begin the work.
