 position of independence. The iron wharf was completed in 1841, and is constructed of iron piles, each of which weighs two and three quarter tons, driven seventeen feet below low water mark, and faced with plates of the same metal, seven or eight inches thick, which are rivetted to the flanges of the piles, and filled in at the back with concrete. The wooden pier, about 400 feet in length, and abutting on the north extremity of this massive structure, was finished in 1845, and roofed over shortly afterwards. On the 22nd of July in the ensuing year, the last stone of the wharf wall, erected by Mr. Julian A. Tarner, of Fleetwood, and extending fourteen hundred feet from the south end of the iron wharf in the direction of the railway, was laid; and at the same time the coal-shoots connected with the new portion of the quay were approaching completion.

The improvement of the harbour was entrusted to Captain Denham, R.N., F.R.S., under whose superintendence the seaward channel of the river was buoyed and beaconed, being rendered safe for night navigation by the erection of a marine lighthouse, in 1840, at the foot of Wyre, nearly two miles from the mouth of the river at Fleetwood. This lighthouse was the first one erected on Mitchell's screw-pile principle. The house in which the light-*keepers lived was hexagonal in form, and measured 22 feet in diameter, from angle to angle, and nine feet in height. It was furnished with an outside door and three windows; and divided within into two compartments, one of which was supplied with a fireplace and other necessaries, whilst the second was used purely as a dormitory. The lantern was twelve-sided, 10 feet in diameter and 8 feet in height to the top of the window, the illumination it produced being raised about 31 feet above the level of the highest spring-tide, and 44-1/2 feet above that of half-tide. A few years since, in 1870, this lighthouse was carried away by a vessel, and for some time a light-ship occupied the station, but subsequently another edifice, similar in appearance and construction to the original one, was raised about two hundred yards south of the same site.

Captain Denham, having accomplished his survey of the river and harbour, issued the following report in 1840:—

"The river Wyre assumes a river character near Bleasdale Forest, in Lancashire, and after crossing the line of road between Preston and Lancaster, at
