Light-houses necessary for the navigation of the Irish Channel.
In the course of the correspondence on this subject, it had been stated by Mr Quintin Leitch, Chief Magistrate of Greenock, a gentleman well acquainted with the navigation of these seas, that if light-houses were erected upon the Isle of Man, these, with the lights of Copeland and Kilwarlin, on the Irish side of the channel, together with the proposed light on Corsewall Point, and another on the Hulin or Maiden rocks, off the coast of Antrim, would fully protect this important part of the coast.
Foundation-stone of Corsewall Light-house laid.
After considering the subject in its various bearings, the Board resolved, as before noticed, on the erection of a light-house on Corsewall Point, in the month of January 1815, and on the 17th day of June following, the foundation-stone was laid, by Mr Quintin Leitch, as master mason, when Mr James Spreull, Chamberlain of the city of Glasgow, Mr Lachlan Kennedy, under whose charge the works were placed, and the Engineer, assisted at the ceremony. In the course of the Summer and Autumn, the tower of this light-house was got to the height of 35 feet, and some progress was also made with the walls of the house for the light-keepers.
1816.
Light-house finished.
The works at Corsewall being suspended during winter, were again resumed in the ensuing spring. The light-room was completed in the autumn, and the light was exhibited to the public on the night of the 15th day of November 1816, agreeably to the following description.
Description of Corsewall Light.
“Corsewall light-house is situate in the county of Wigton, in North Lat. 55° 1´, and West Long. 5° 5´. It bears by compass, from Millour Point, on the western side of the channel leading into Loch Ryan, W. by S., distant about two miles; from Turnberry Point, SW. 21 miles; from the Craig of Ailsa SS. W. 15 miles; from the Mull of Kintyre S. E. S. 31 miles; from the Hulin or Maiden rocks on the coast of Antrim, E. by S. 20 miles; from Copeland Light-house, near the entrance of Belfast loch, NE. ½ E. 22 miles, and from Laggan point in Galloway, NE., distant 3½ miles. To distinguish this light, which is from oil, with a reflecting and revolving apparatus, from the other lights upon the coast, it is known to mariners as a Revolving light with colour, and exhibits from the same light-room a light of the natural appearance, alternating with a light tinged with a red colour. These lights, respectively, attain their greatest strength, or most luminous effect, at the end of every two minutes. But, in the course of each periodic revolution of the reflector-frame, the lights become alternately fainter and more obscure, and, to a distant observer, are totally eclipsed for a short period. The light-room at Corsewall is glazed all round, but the light is hid from the mariner by the high land near Laggan Point, towards the south, and by Turnberry Point towards the north. This light is elevated 112 feet above the medium level of the sea, and its most luminous side may be seen like a star of the first magnitude, at the distance of five or six leagues, but the side tinged red being more obscured by the colouring shades, is not seen at so great a distance.”
