In consequence of this arrangement, a vessel of about 100 tons burden was chartered and fitted out with stores and other necessaries for the use of the Northern Light-houses; and in the course of the summer of 1791, Mr Smith made his first annual visit by sea to the light-houses--the journeys of the engineer having hitherto been performed chiefly by land. On this voyage, every thing was reported to be in good order at the several stations, excepting at the Light-house of North Ronaldsay, which he found to be very improperly kept: it appeared also that the light-keeper at this station had been embezzling the stores committed to his charge. This person was formerly a ship-master, who, finding it difficult to get employment in the line of his profession, had been very improperly recommended to the attention of the Light-house Board. Under circumstances of such misconduct, the engineer immediately dismissed him from the service, and his conduct was further taken cognizance of by the Sheriff of the county. [Sidenote: Economical plan of the early Light-houses.] The business of the Light-houses was now so arranged, that matters went on in a very prosperous and successful manner. So well, indeed, had the plans and buildings of their engineer been considered, and made to meet the slender funds of the Board, that, with an expenditure of little more than L. 10,000, five lights had been exhibited upon the coast. Though these buildings were unavoidably very much circumscribed in their accommodations, and even temporary in their construction, yet the speedy exhibition of the lights was of great benefit to navigation, while the improving state of the light-house duties enabled the Commissioners to extend their influence along a greater range of coast; and the different buildings have since been enlarged and completed in a much more substantial manner, by applying the surplus funds to these purposes. [Sidenote: ~1793.~] [Sidenote: Application for additional light-houses.] In the year 1793, the prosperous state of funds induced and enabled the Commissioners to attend to the applications of mariners for additional light-houses on the coast. In particular a letter, to be afterwards more fully noticed, was addressed to the Light-house Board by Admiral Sir Alexander Cochrane, then commanding his Majesty’s ship Hind upon the Leith station, setting forth the great benefit that would accrue to shipping, from the erection of a light-house upon the Bell Rock. Representations were likewise made at this time by the merchants of Liverpool, regarding the propriety of erecting a light-house upon the Skerries, situated in the middle of the Pentland Firth , which separates the Orkney Islands from the Mainland of Caithness. The object of a light here, was to open this Firth as a passage to shipping in general, and to enable the mariner to avoid a circuitous and dangerous voyage to the northward of the Orkney Islands.
