This application having been complied with, Sir William Rae was requested to attend to the progress of the bill, and to take the assistance of any of the other members of the light-house board who might happen to be in London at the time. The Isle of Man Light-house Bill was accordingly brought forward by Mr Huskisson, in absence of Mr Canning, member of Parliament for Liverpool, as a measure in which that port was specially interested. But when the subject was communicated to the late Mr Rose, M. P., one of the elder brethren of the Trinity House of London, he requested that nothing might be done in this measure, until he should have an opportunity of consulting with the gentlemen of the Trinity-House, as he considered the Isle of Man to be within the district of that board. After repeated meetings, at which Mr Rose attended, he ultimately stated, that the Trinity Board did not consider the Isle of Man as coming under their line of coast; and that the Commissioners of the Northern Light-houses might, therefore, go on with their bill. It was accordingly brought forward in the House of Commons, and the author attended to prove the preamble of the bill in the House of Lords; and in June 1815 it received the Royal assent. [Sidenote: Difficulty in fixing the position of the Isle of Man lights.] In returning towards Scotland, I embarked in the Light-house Yacht at Liverpool, and visited the Isle of Man. It appeared, on examining the site for the erection of a light-house on the Point of Ayre, or northern extremity of the island, that there would be no difficulty in fixing its place. But the case was different at the Calf Island, as there seemed an evident advantage in having the house on a low situation, to keep it more free from fog, and where it might also be more in the line of direction with a dangerous reef called the Chickens, lying about a mile into the offing. On this low position, called Kaager Point, the high land of the Calf would have shut in the light very much from the northward. Another situation, however, presented itself; but, as this last station was considerably higher, it might perhaps be found more uncertain with regard to fog resting upon it in thick and hazy weather; and it was therefore thought prudent to place a trusty person on the island, with directions for observing and communicating the state of the weather for about six months, previously to determining the site of the light-house on the Calf of Man. This mode of inquiring into the subject, was strengthened by the report of some intelligent persons relative to the prevailing state of the weather at the Isle of Man, who represented that the Calf Island was less liable to be enveloped in fog than the higher parts of the Main Island.
