RETURNING to the old coach road from this expedition, and coming to it again with a thankful heart, we presently come to Stretham Bridge, a narrow old hunch-backed brick structure spanning the Great Ouse, or Old West River, and giving entrance to this Isle of Ely, of which already we have heard so much, and will now hear more. The sketch-map that has already shown the Conqueror's line of march indicates also the size and shape of the Isle: the physical Isle. For there are really two, the physical and the political. The last-named comprises the whole of the northern part of Cambridgeshire, from this point along the Ouse to Upware, and thence, following the Cambridgeshire border, round to Littleport and Tydd St. Giles in the north, by the neighbourhood of Crowland and Peterborough, and so down to the Ouse again at Earith, Aldreth, and Stretham Bridge. It is still a political division, and has its own government, under the style of the County Council of the Isle of Ely. The real geographical Isle--the one sketched in the map--is much smaller; only one-third the size of the other; measuring in its greatest length and breadth but some twelve and eight miles, and bounded by the Great Ouse from Earith to Upware, by Cam and Little Ouse to Littleport, and thence by the Old Croft River to the New Bedford River, returning along that cut to Earith. As you approach Stretham Bridge along this old causeway the Isle is plain to see in front, its gentle hills glimpsed between the fringe of willows and poplars that now begin to line the way. No one has bettered the description Carlyle wrote of the Fen-country seen from this causeway that was once the Akeman Street; and no one _can_ better it. "It has a clammy look," he says, clayey and boggy; the produce of it, whether bushes and trees or grass and crops, gives you the notion of something lazy, dropsical, gross. From the "circumfluent mud," willows, "Nature's signals of distress," spring up by every still slime-covered drain: willows generally polled and, with that process long continued, now presenting a very odd and weird appearance. The polled crown of an ancient willow bears a singularly close resemblance to a knuckly fist, and these, like so many gnarled giant arms of bogged and smothered Goliaths thrust upwards in despair, with clenched and imprecatory hands, give this road the likeness of a highway into fairyland whose ogres, under the spell of some Prince Charming, have been done to death in their own sloughs. Pollards, anathema to Cobbett, are in plenty in these lowlands, but it must not be thought that because of them, or even because Carlyle's description of the country is so apt, it is anything but beautiful. Only, to see its beauties and appreciate them, it is necessary here, more than elsewhere, to have fine weather. [Illustration: A FENLAND ROAD: THE AKEMAN STREET NEAR STRETHAM BRIDGE.]
