Drain channel system along the line of an ancient north-south road, the channel in part at the surface and in part tunneled and accessible by shafts. Over a considerable part of this channel the hard water deposit at the bottom, belonging to the period of use, is consistently of the second and early third centuries, although coins of Gallienus in the upper part of the filling show that the channel was not abandoned before the time of the Heruli. The channel actually extends over a considerable area (E-F 5-6).
