Such was the last serious exercise of the Bishop's long-descended secular jurisdiction over the Isle. From the Girvian Princes to the Abbesses of Ely, from the Abbesses to the Abbots, from the Abbots to the Bishops that Palatinate jurisdiction had been handed on for twelve hundred years;—and this was its sordid close. It died none too soon.
Littleport is now quite a thriving and prosperous place, with a shirt-factory employing over 300 hands and a most effective system of agriculture in the reclaimed fens around. It has a fine Early English church, and a grand tower, through the basement of which goes the footway of the street. Until the nineteenth century the place was so inaccessible by land that the Cambridgeshire annalist Carter (1752) tells us that "it is as rare to see a coach at Littleport as a ship at Newmarket."
From Littleport the road pursues its level way for seven miles across the fen, till, after crossing the small islet of Hilgay, it strikes the Norfolk uplands at their south-western corner, hard by Denver Sluice; the present boundary of the North Sea tide, which once ran up almost to Cambridge. This magnificent Sluice is the keystone of the whole drainage scheme of the fenland. Here the New and the Old Bedford Rivers, whose start we saw at Earith (p. [280]), once more rejoin the Ouse, having conveyed in twenty-two miles the waters which by the old channel would have taken thirty-three. This, of course, gives them a better fall, and renders them less liable to silt themselves up.
Practically the New River does all the work, very little water being in the Old except what the tide brings up. It is a striking sight to be on the Sluice at high water and gaze at the sea waves ridging up this old river with force that seems illimitable. And yet not enough pass in, before the ebb calls them back, ever (or hardly ever) to reach Earith, as a glance at the channel there instantly shows. Still more striking is it to be on the Sluice when the spring tides are on, and see the sea on the north of the Sluice standing fifteen or twenty feet higher than the fresh waters on the south. One realises what widespread disaster would ensue if the Sluice were to give way. Small wonder that during the Fenian dynamite scare of 1867 the place was watched day and night by a guard of soldiers. The Sluice itself is a massive dam of stonework; having a big lock with two sets of gates, one against the stream of the river, the other against the tideway of the sea, which reaches this point by a broad cut from the important seaport of King's Lynn.
This present erection was built 1752. Its earlier predecessor was set up 1651 by the Dutch engineer Vermuyden, the maker of the Bedford Rivers, to whose genius the whole present scheme of drainage owes its existence. He carried through his plan in face of most determined opposition, especially from the towns of Lynn and Cambridge, who complained that "whereas of old ships from Newcastle were wont to make eighteen voyages in the year to Cambridge with sea coal, now, since the blocking of the stream at Denver and the diversion of its waters at Earith, they can make but ten or twelve, whereby the price of fuel hath increased by half." When this first sluice was "blown up" by the tide in 1713 there were loud rejoicings. The consequences, however, proved so serious, that the next generation was fain to see it replaced.
Lynn is the point to which the road we have been following ultimately leads. On leaving Ely by this road, the first turn to the right will bring us down to the famous Roslyn (or Roswell) Pit, beloved of geologists and botanists. It is a large water-filled excavation by the side of the railway, nurturing various rare water plants, and presenting the wonderful spectacle of chalk lying above boulder-clay, a phenomenon now attributed to ice action.[236]

The western declivity of the Island plunges down to the fen at Mepal, on the New Bedford River. After crossing this, the road leads straight across the fen to Chatteris, and is called Ireton's Way; the causeway on which it runs having been made by that great Puritan general, for strategic purposes, during the Civil War. Chatteris was the first of the wonderful chain of Abbeys which swept round the Fenland from Ely into Lincolnshire. The others are Ramsey and Peterborough on the last verge of the mainland; with Thorney and Crowland, rising, like Chatteris, on islands in the morass.[237] Of these, Chatteris and Thorney alone are in Cambridgeshire; though Peterborough is within half a mile of the county boundary. The former, a nunnery, was founded by the Lady Alwyn, foster-mother to Edgar the Peacemaker. It was never a large House, and no remains of it survive; but Chatteris is now the seat of another Benedictine community, exiled from France in 1901. The place possesses some curious wells of warm water, not of any great depth, as such usually are, but penetrating only some ten or twelve feet into the fen deposits. Local chemical decomposition is supposed to account for the phenomenon. The fen hereabouts is rich in geological and archæological remains. And within sight of his mother's convent, only six miles away across the fen, her son (also an Alwyn), the Alderman or Earl of the district, founded, on the projecting cape of the Huntingdonshire mainland, the much larger abbey of Ramsey, whose abbot was one of the higher or "mitred" class, privileged to give the "Minor" Orders (i.e. those beneath the grade of Deacon).
