The meaning of the word _Cardike_ is no more than Fendike: we use the word still in this country, to signify watery, boggy places: it is of British original. I doubt not but that the Romans likewise made that other cut, between Lincoln river and the Trent, called the Foss: the name seems to indicate it, as well as the thing itself; for it is but a consequent of the Cardike, and formed on the same idea: so that I suppose it was not originally cut, but scoured by Henry I. as Hoveden mentions: then the navigation was continued by land from Peterborough quite to York, and this was very useful to the Romans in their northern wars. The other way they might come from Huntingdon. The 20th of October, 1726, I traced the Cardike round the out-skirts of Sir William Ellys’s park of Nockton: it runs near the site of the old priory, whose ruins are just visible: it bounds the park entirely on the fen side, and is very perfect thereabouts; the high-country streams from Dunston, and others, running along it. We saw where it crossed a marshy valley, and reached the opposite high ground in its course to Washenburgh. A well of the old priory is well preserved, remarkably good water. That part of the Cardike between Lincoln and the Trent was begun to be cleansed by bishop Atwater, but he died before completed. It is highly probable that the Romans called our Cardike _Fossa_, which happens to be preserved only on that part between Lincoln and the Trent. The Fossdike in being in Edward the Confessor’s time. Vide Camden, _Nottingham_. Cardike runs close by Thurlby town end. The marquis of Lindsey gave me an exceeding fair Maximinus; the reverse, +GENIO POP. ROM.+ found at Grimsthorp. Mrs. Tichmus of Stamford told me she once had many Roman coins, from a great parcel found at or near Sleford. The 18th of October, 1728, I travelled on the Roman road, the eastern branch of the Hermen Street from Sleford, for about three miles southward. I observed that it went not to Sleford town directly, but to the old house of Sir Robert Carr’s, formerly Lord Hussey’s (attainted for treason in time of Henry VIII.) called Old Place. We saw by the way, on the east side the road, a mile or more south of Sleford, an old work, square, ditched about, large, with an entry from the road; the earth of the vallum thrown on both sides.
