Survey, p. 205. {99e} The Roman generals are supposed to have imported Belgian workmen, and by their aid, with their own soldiers, and the forced labour of the Britons, to have made the huge embankments, of which there are remains still existing in “The Roman Bank,” near Sutterton and Algarkirk, Bicker, and other places. The Car Dyke, skirting the Fens, on the west, some four miles from Kirkstead, was their work, and a few miles westward is Ermine Street, the great Roman highway, which stretches from Sauton on the Humber to London. {101a} The revolution effected in the drainage of the Fens was not accomplished without considerable and even violent opposition on the part of many of the inhabitants, who thought that their interests were being ruthlessly disregarded, and in some cases even their means of subsistence destroyed. The state of affairs at this period, and the measures resorted to, are very graphically described in the historic novel, “A daughter of the Fens,” written by Mr. J. T. Bealby. This book the present writer would recommend to visitors to our Lincolnshire health-resort, as likely to give them an interest in the neighbourhood. {101b} Mr. H. Preston, F.G.S., of Grantham, goes into the matter rather fully in the “Naturalist” of 1898, pp. 247–255; as also Mr. F. M. Burton, F.L.S., F.G.S., of Gainsborough had previously done, in the “Naturalist” of 1895, pp. 273–280.
