The Ellesmere navigation, or the Shropshire Union railway and canal company may be called a system of canals extending through the large and fertile tract of country which lies between the banks of the Severn and those of the Mersey, and between the confines of North Wales on the west and the borders of Staffordshire on the east—a space of fifty miles in length, and more than twenty in breadth, exclusive of the valleys which open into North Wales. Its grand object is to unite the Severn, the Dee, and the Mersey, and by that means to open a communication from the above mentioned districts to the ports of Liverpool and Bristol. There is a short canal formed by the Marquis of Stafford, which commences at Donington Wood and proceeds to Pave-lane, near Newport, a distance of nearly seven miles, with a branch to his lordship’s lime works at Lilleshall, This canal was made for conveying coal to the latter place from the works at Donington, now held on lease by the Lilleshall company. The Montgomeryshire canal, a branch of Ellesmere, also passes through a portion of this county. LAKES OF SHROPSHIRE.—The lakes of this county are neither numerous nor extensive. At Marton, near Baschurch, is the Marton and Fennymere pool, covering 96A. 2R. 15P. At Marton, near Chirbury, is a pool covering 40A. 2R. 37P., from which issue three streams running in different directions. At Ellesmere is a magnificent sheet of water covering 116 acres; Colemere 87 acres; Crosemere 44 acres; Whitemere 62 acres; Blackmere and Newtonmere are in the same neighbourhood. A fine sheet of water at Shrawardine covers 40 acres. South of the Severn are a few small lakes, but not of any considerable extent. Thus the part of the country which abounds most in running water has the fewest pools. At Walcot and Hawkstone are lakes of considerable extent, the latter stretches two miles in length. Sundorne, Halston, and Tong, have embellishments of the same kind.
