Translation of de metatione castrorum?

[D B Campbell]

There should be one more English translation in:
Richardson, A. 2004. Theoretical Aspects of Roman Camp and Fort Design, BAR S1321, Oxford.
But I haven't seen this one.

I haven't seen that volume, either. But I believe -- I may be wrong -- that it includes a translation which Sir Ian Richmond presented to his colleague F.G. Simpson at Christmas 1925, and which was discovered amongst his papers. If it is this one, it includes one or two questionable passages, but is generally serviceable if you have nothing else.
