The estimate for this line is £72,270; and for the Chichester Branch, which is level and one mile, two furlongs and three chains in length, is £6,500. This canal and branch is supplied from Chichester Harbour with water, which is lifted by a steam engine at that end of the canal. The canal is according to section 33 feet at top, 19 feet 6 inches at bottom and 4 feet 6 inches deep. The channels from the end of the main line of canal in Chichester Harbour, round Thorney Island and Hayling Island by Thorney and Langstone Wadeways, and Langstone Harbour, to the end of the Portsea Canal, is thirteen miles and one furlong. The estimate for making these wadeways sufficiently deep is £12,914. The canal from Eastney Lake is two miles, three furlongs and two chains in length; there are two locks of 5 and 7 feet at the east end, and a basin at the teranination at Portsea. This part is 5 feet deep, and the estimate £18,618; it is supplied with water by an engine. The distance from the end of the main line of canal in Chichester Harbour to the canal at Cosham is fifteen miles and two furlongs, and the length of the canal to Porchester Lake in Portsmouth Harbour is one mile, two furlongs and four chains. This branch is 7 feet deep with two sea locks, one at each end of the canal of 10 feet rise each; the estimate £15,188. The total estimate is £125,490. The surveys were made by Messrs. Netlam and Francis Giles, of London; the estimate and execution of the works by the late Mr. Rennie.
