A New Lighthouse
The following notice has been forwarded to us by a friend who has just been enjoying the beauties of the Thousand Islands:
A light house has recently been erected at Tibbett's Point, (Lake Ontario,) in this State, which, as being the second of its class introduced on our great inland waters, calls for a special notice. The new lighthouse occupies a position some seventy feet eastward of the old light, which has now done its service of nearly thirty years, "for better, for worse." Its shafts of brickwork is of the proportions of a Grecian Doric column - forty-seven feet high, twelve feet six inches in diameter at base. This shaft is surmounted by a solid cut-stone cap, thirteen feet in diameter, which forms the platform of the lantern section. Upon this cap rises a brick platform, circular on outside and octagonal within, three feet high; and this is covered with a cut-stone coping through the six inches thickness of which the iron posts of the lantern are inserted or secured. The lantern is an octagon, six feet and a half in diameter and fifteen feet high, comprising seven lights of French plate glass, 40 x 30, and 3/8 of an inch in thickness, clear as crystal - the eighth, or remaining side of the octagon being an iron door opening on the stone platform, there being a space of over two feet, protected by an ample iron balustrade around the lantern section. From this height the view all around is very fine, presenting the adjacent islands on Lake Ontario, as well as those of the River St. Lawrence, at whose head this graceful structure stands, and the craft of every class in transitu upon their commercial errands to or from Ogdensburgh, French Creek, Cape Vincent and the several ports on Lake Ontario, or our Upper Lakes, via Welland Canal. The interior of the shaft is a cylinder of 6.6 sec. diameter throughout its height. The ascent for the first thirty feet is by light cast-iron stairs, winding round a pillar at centre, about three inches diameter. This space is lighted by two windows opening on hinges and through which beautiful view may be had, recesses for resting places being provided. From the landing at the head of the stairs, an iron ladder, seven feet long, gives access to the cleaning room - a neat, well ventilated apartment, in which is the closet for the utensils, etc., of the lighting apparatus. Another iron ladder, eight and a half feet long, conducts to the lantern. The man-holes to both cleaning room and lantern are closed by iron trap-doors on hinges, and the slightest possibility of fire completely guarded against. The floors being inch thick iron also.
Upon a handsome iron pillar three feet and a half high, at the centre of the lantern floor, is set the illuminating apparatus, on the dioptric system of M. Fresnel. This consists of lenticular sections forming a cut-glass globe, somewhat resembling in outlines an egg set upon its end; which lens are so arranged that all rays of light which would (as in ordinary lamps) be lost above or below, are taken up and sent into the focal flame, thus economising light and applying it directly to the purpose it is intended to serve.
The mariners of Ontario and the St. Lawrence are well satisfied that this new aid to navigation is all that is required - presenting, as it does, a vivid light, quite distinct in color from any other around, and therefore easily detected and always reliable. On the whole the Tibbett's Point new Light House is a great improvement on the old system, and it is satisfactory to know that the Light House Board contemplates the introduction of this reformation in lanterns and lamps as speedily as circumstances will permit. The lighthouse about to be erected at Green Island, as well as the iron Screwpile Beacons at Maumee Bay, both on Lake Erie, will be on the improved principle; and the day is not far distant when the old system of imprisoning from a dozen to two dozen lamps in a thickly cross-barred cage, will be classed among the curiosities of Chinese philosophy or Japan Ingenuity.
I stated in commencing this notice that Tibbett's Point was the second of the Fresnel lights on our lakes. The first was erected at Gooshance, Straits of Mackinac, by that estimable officer, the late Captain Canfield, T.E., under the direction of the Bureau of Topographical Engineers.
