Inchkeith Revolving Light.
Description of Inchkeith Revolving Light.
The above description, in so far as regards the appearance of the light of May being exactly applicable to that of Inchkeith, described at page [25]. of this Introduction, it was found expedient to alter it from a stationary to a revolving light, that it might be distinguished from the light of May, where a revolving light would have been liable to be mistaken for the Bell Rock light, owing to the more contiguous position of the May island to the Bell Rock.
The light upon Inchkeith, hitherto a stationary light from oil, with reflectors, was therefore altered and converted into that description of light known to mariners as a Revolving light without colour, on the same night that the change took place upon the Isle of May. The light of Inchkeith is seen from all points of the compass, at the distance of five leagues in favourable weather, exhibiting a bright light once in every minute, and gradually becoming less luminous, it totally disappears to a distant observer. In this manner, each periodic revolution of the reflector-frame, alternately shows a brilliant light, which becomes fainter, and more obscure, until it is totally eclipsed. By this alteration, the same description and appearance of the other lights upon the coast is preserved, and the possibility of mistaking Inchkeith light for the numerous lights on the land, with which it is surrounded, is now also effectually prevented.
Corsewall.
1815.
Additional Light proposed for the western coast on Corsewall Point.
It had long been the wish of the mercantile interest of the Firth of Clyde and St George’s Channel, to have a light on the coast of Galloway, to direct ships, on the Scotch side, into the Irish Channel. From the great amount of light-house duties collected upon the western coast, and the extent of light-house works which had of late years been erected upon the eastern shores, including the Bell Rock and Isle of May light-houses, the Commissioners were desirous of accommodating the trade of the western coast, as far as the demands of shipping required, or the state of the light-house funds would permit. It was accordingly resolved, that a report upon this subject, made to the Light-house Board by the author, should be submitted to the trade of Liverpool, Glasgow and Greenock, for their observations. Having in this manner procured the necessary information, it was resolved that a light-house should be erected for the benefit of this coast, upon the northern extremity of the Mull of Galloway in Wigtonshire, on the point of Corsewall; because, in addition to the advantages of this situation, as an excellent direction both for the entrance of the Irish Channel and Firth of Clyde, it would answer as a guide to the Roadstead or anchorage of Loch Ryan.
