But it was not enough for the Romans thus to provide for commerce and travelling, without they set proper stations or mansions for the reception of negociators and the like. Accordingly we find the distance between Caster and Lincoln, about 40 miles, has two towns upon it at proper intervals for lodging; these are Sleaford and Stanfield: the original names of them are in irrecoverable silence, but the eternity of the Romans is inherent. At Sleaford they have found many Roman coins, especially of the Constantine family and their wives, about the castle and the spring-head a little above the town. It is probable that Alexander, the bishop of Lincoln, built his work upon the site of a Roman citadel. Beside, at Sleaford comes in the other Roman road from the fen country by Brig-end causeway, and at the intersection of these two roads the old town stood. At Stanfield, which is a little village near Burn, they find daily the foundations of buildings, innumerable coins and other antiquities, of which yourself and our friend Mr. John Hardy have a good quantity. These are chiefly dug up in a close called Blackfield, from the extraordinary richness of the ground. It stands half a mile off the road upon elevated ground, whence you may see Spalding, Boston, and the whole level: it is now only of some note for a good chalybeat spring. I shall rehearse a few things I have noted hereabouts, and then we will descend into Holland. The following antient part of the genealogy of the inheritors of Brun, or Bourn, contains several antiquities hereabouts. The spring-head at Bourn, near the castle belonging to them, is remarkable for its largeness and quickness.
