172 HAZZLEDINE WARREN : STUDY OF PRE-HISTORY IN ESSEX. 
Shoebury (F. C. J. Spurrell, E.N., iv., 1890, pp. 150-153, 
plan). Little remains, but it appears to have had nearly 
straight sides and rounded corners. There is no inner 
enclosure. The author refers its construction to the Dane 
Haesten, A.D. 894. 232 
Maldon (E. A. Fitch, E.N., ii., 1888, pp. 234-235), situated to 
the W. of the town, on the London Road, now very obscure. 
Enclosed about 22 acres. Considers it to be the Saxon 
Burg “ wrought and getimbred ” in A.D. 913 or 920. 233 
Birch Castle, near Colchester (H. Laver, E.N., viii., 1894/ 
p. 204). Situated S.E. of Birch church. The circuit of the 
earthworks still remains. The date is unknown, but may 
be Roman. 234 
Pictsbury Ramparts (T. V. Holmes, E.N., i., 1887, pp. 79, 
82). Situated 3 miles N.W. of Colchester. About | of the - 
oval of the camp has been levelled for farming. 235 
Camulodunum (H. Laver, E.N., ii., 1888, pp. 120-122). The 
area of this British Oppidium is bounded on the W. by . 
Grymes Dyke, and on the other sides by the Colne and 
the Roman River. It was the ancient fastness of the 
Trinobantes, became the royal town of Cunobelinus, and 
was subsequently occupied by the Romans (the Colonia 
of Claudius). Weapons of flint and bronze, urns, and 
British coins (as also Roman remains) are abundant in the 
Oppidium. It is the centre of three British roads, some 
parts of which only survive as foot-paths. Considers that 
some of the apparent earthworks here are really banked 
Roman roads. 236 
Asheldham (E.N., xvi., 191T, p. 232). Brief note. The camp 
may be Danish. 237 
Harwich ( E.N ., vi., 1891, p. 246). Some remains traceable' 
vS. of the town. 238 
Comprehensive (T. V. Holmes, E.N x., 1897, pp. 145-158, 
numerous plans). Compares the earthworks of Essex with 
those of the Southern Counties, and of Norfolk and 
Suffolk. 239

In general review of the above notices of earthworks, one 
can only say—how little we know about them ! 
XIII. Streamlet Dams. 
Felstead (J. French, E.N., vi., 1892, pp. 34-40). Describes, 
artificial dams, 150 to 200 yards long and 20 feet high, 
across streamlet valleys ; and sections through their silt. 
Many oyster shells and one or two pieces of Roman pottery 
were found in circumstances which rather suggested con-
