Island Glass
1789.
Considerable progress had been made in the course of the former season with the erection of the Light-house at Island Glass in Harris, which was finished and lighted on the 10th day of October 1789, the following being its specification:—The Point of Island Glass, one of the Harris Isles, is situated in North Lat. 57° 50´, and Long. 6° 33´ west of London. Ru-Ushiness bears from the light-house, per compass, E. NE. ½ E., distant 8 miles; northern extremity of Shiant Isles E., ½ S., southern extremity of ditto E. by S. ½ S., distant 11 miles; Skerne Rock SE., ½ E., distant 3 miles; Skergraidish Rock S. SE. ¼ E., distant 9 miles; Point of Trotternish in Sky S. SE. ¼ E., distant 16 miles; Point of Vaternish S. SW. ¼ W., distant 15 miles; Dunvegan-Head SW. ½ S., distant 20 miles; Point of Roudil, at the entrance of the Sound of Harris, W. by S., distant 14 miles. The light-room is elevated 70 feet above the medium level of the sea, and will be seen from E. NE. ½ E., from W. by S., and intermediate points of the compass south of these points.
North Ronaldsay Light-house.
While the works of Island Glass were proceeding, a light-house was also erected, and lighted 10th October 1789, on the island of North Ronaldsay, in Orkney; but, as the light at this station was afterwards removed to the neighbouring island of Sanday, it will fall more properly to be noticed in the form of a Tower or Beacon, into which the building was converted, after a Light-house had been established at the Start Point of Sanday.
