The preses informed the meeting, that he had corresponded with persons the most likely to afford information relative to the best construction of Light-houses, and had received answers from Liverpool to a variety of queries regarding Light-houses, where the use of coal-fires had been laid aside, and where oil lights, with reflectors, had been introduced: That he had also got various plans and estimates for Light-houses lighted with oil: That the Chamber of Commerce of Edinburgh had furnished a plan of the Light-house on the Island of May, in the Firth of Forth, and also a description of the light on the Island of Cumbraes, in the Firth of Clyde, both of which were then open coal-fires: In particular, that he had received from the late Mr THOMAS SMITH of Edinburgh, plans and observations on the construction of Light-houses with Lamps and Reflectors; which having been ultimately approved of, Mr Smith was nominated Engineer to the Board. After appointing a Committee for preparing matters for a general meeting, they adjourned till the 23d of January 1787. [Sidenote: Transactions of 1787.] In pursuance of the act of Parliament, the Commissioners gave directions that a correspondence should be opened with the several proprietors of the land where the four original Light-houses were specified to be erected. An answer was immediately received from Mr Traill of Westness in Orkney, requesting the Board’s free acceptance of the ground necessary for erecting the Light-house proposed for the Northern Isles of Orkney, on any part of his property. Application was made to the Duke of Argyle, as to the ground for the erection of a Light-house on the Mull of Kintyre; to Lord Saltoun, relative to the station of Kinnaird-Head, in Aberdeenshire; and to Mr Macleod of Harris, as to the site of a Light-house on Island Glass. Measures were also taken for obtaining fit persons to contract for erecting the necessary buildings, and for conducting the operations at the different stations. _Kinnaird Head._ [Sidenote: Kinnaird-Head Light-house.] The result of the correspondence with Lord Saltoun, was the purchase of the old building of Kinnaird Castle from his Lordship, on which a lantern or light-room was erected. After encountering considerable difficulties in the outset of this establishment, the house was got ready for the exhibition of the light by the month of December 1787, and the following notice to mariners was officially given by the Secretary in the London Gazette, and in the Edinburgh, Glasgow, and Aberdeen newspapers.
