sings Shelley; and this dreary outcome of mudbank and bog and mere had its wooded isles, very fair and lovely to behold, redeeming the desolation of the landscape. Such were Ramsey, Lindsey, Whittlesea, whose names remind us of their whilome characteristics (_ea_, _ey_, an island). In these green places the old monks loved to build their quiet abbeys, rearing their herds in rich pastures, feeding fat fish in their tranquil streams, and dreaming in the shadow of green alder and stately ash. But these Eden-isles were few, and the surrounding marsh was black and dismal enough to scare the boldest spirit, and pestilential enough to sap and undermine the strongest frame. The Romans had attempted to drain and embank it, and their _vallum_ may still be tracked along the surface of the marsh-lands, marked to this day by the names of Walsoken, Walton, and Walpoole. In the Middle Ages, however, it returned to its primeval desolateness--a waste and wilderness, haunted by the foul legends of an unwholesome superstition. In the immediate neighbourhood of the great monasteries of Crowland and Ely, and of the thriving towns, the good work of drainage went on slowly; but elsewhere the land was given up to the bittern and the heron. No comprehensive scheme was adopted, however, until Russel, Earl of Bedford, cut the great Bedford River, twenty-one miles long, and rescued from the desert the rich tract known by his name--the Bedford Level. "Erst A dreary pathless waste, the coughing flock Was wont with hairy fleeces to deform; And, smiling with its lure of summer flowers, The heavy ox, vain struggling, to ingulf; Till one, of that high-honoured patriot name, Russel, arose, who drained the rushy fen, Confined the waves, bade groves and gardens bloom, And through his new creation led the Ouse And gentle Camus, silver-winding streams."[17] The work was continued by William Earl of Bedford, who added, in 1649, to his father's old "Bedford River" that noble parallel river the Hundred Foot, both rising high above the land to allow for flood water. It was carried on at a later period under the direction of Government surveyors. Then came Rennie, the great engineer, whose operations effectually shut out the desert, and handed over to the agriculturist nearly the whole level of the Fens, some seventy miles in length. Works are now in progress for rescuing a further portion of the basin of the Wash, to be formed into a new county, and named after the Queen. So that now, in tracts once covered by the sea, or knee-deep in reedy, slushy, pestilential slime, the grass grows luxuriantly, the crops wave in golden abundance, or the breeze takes up and carries afar-- "The livelong bleat Of the thick-fleecèd sheep from wattled folds."
