Beyond these there is another empty space or road left, one hundred feet broad, parallel to the tents of the Tribuni, skirting the market-place, Praetorium, and Quaestorium, from agger to agger. On the further side of this road the rest of the equites extraordinarii are placed facing the market-place and Quaestorium: and between the quarters of these cavalry of the two legions a passage is left of fifty feet, exactly opposite and at right angles to the square of the Praetorium, leading to the rearward agger.

Back to back with the equites extraordinarii are the infantry of the same, facing the agger at the rear of the whole camp. And the space left empty on either side of these, facing the agger on each side of the camp, is given up to foreigners and such allies as chance to come to the camp.
