ROMAN POTTERY FOUND IN BRITAIN.

—which is the prevailing one among Continental archaeologists, 
is likewise requisite in dealing with the York collection, in order 
to be useful or complete. This is owing to the fact that the 
productions of local potteries of the Roman period in our 
museums are often indistinguishable, and that some of the most 
important centres of production in Britain are still unknown or 
unexplored. 
The pottery finds from the Roman camp of the Augustan 
period at Haltern, in Westphalia, dating from B.C. 11 to A.D. 9, 
are arranged by Lceschcke (Haltern V., p. 102), under three 
general headings, I. Roman, II. Belgic, III. German Wares. 
The Roman wares in Class I. are subdivided into (1) Colour- 
coated,—A. Italian, (a) Terra sigillata. B. Provincial, (b) Green- 
glazed, (c) Mica-coated, (d) Varnished. (2) Plain clay-bodied 
vessels. 
Italian terra sigillata found at Haltern, derived mainly from 
Arretine potteries, is replaced in the much later collection at York 
by similar wares imported from La Graufesenque, Lezoux, 
Rheinzabern and other potteries, as stated in parts I. and II. of 
this general description (Reports 1909-1910). 
The green glazed vessels in Class B are unrepresented at York, 
and mica-coated vessels are represented by a few vessels and 
fragments ot colour-coated goblets dusted with mica almost 
imperceptibly, which cannot be looked upon as constituting a 
separate class. 
The native German wares are also entirely wanting at York. 
The grey to black Belgic wares (terra nigra), made in imitation 
ol early sigillata, most frequently copying Arretine forms, though 
present at Colchester and Silchester, have not been observed at 
York. The red variety can, however, be recognised in one or 
two cups and bowls with pinkish-red colour-coating imitating red 
sigillata (Plates V., 7, 8, VI., 18), and saucers or plates with 
slightly turned in rims, and low foot-rings, coated lightly with 
pinkish-red on the visible parts. (Belgic ware included in 
Class II.) 
It happens that a number of vessels of smoke fumed grey-black 
ware, such as bottle-necked urns, carinated or angular bodied 
vessels, small oblique-lipped ollae artificially r roughened with 
raised ridges, or studded with clay knobs round the bulge, bowls 
with flat out-bent rims grooved or reeded on the surface, &c., in
