Avon, over-against it, is another, called too Cheselbury, and said to have a fair _prætorium_ in it. These camps so contiguous, with a river between, seem still remains of Vespasian’s conquests; and that he got the country by inches.

XLIV.] North of these is Martinsal hill, a vast stationary Roman camp, upon a high hill steep to the east, which is seldom observable. I measured it quite round, in company with lord Hertford and lord Winchelsea: it is conspicuous at a great distance, and within sight of all the camps in the country. I take it to have been made when the Romans were thoroughly possessors of the kingdom, and one of their chief fortresses, whence they might give or receive signals all around, in case of distress, by fire or smoke. On two sides the precipice is dreadfully steep. Lord Winchelsea has a brass _Alexander Severus_ found here; on the reverse, _Jupiter fulminans_, with PM. TR. P. COS. On the west side, upon the top of the hill, without the camp is a round pit full of good spring water, always to the brim but never overflowing in the driest summers; which at those seasons is of greatest service to the country round, and thousands of cattle are driven every day from a considerable distance to drink there. I am told there is another such upon the top of Chute hill, south east from hence, very high, and no water within some miles of it. So provident has Nature been in subliming, by some unknown powers, the liquid element to these barren heights, that every part of her works should not be without its graces and use. The prospect from Martinsal must needs be exceeding fine. Salisbury steeple, twenty miles off, bears south-west and by west: the port of this camp is north-east. [Sidenote: +Martinalia.+]
