_Prehistoric._--The prehistoric remains, commonly so-called, such as cutting implements of stone, are only feebly represented, but occasionally they do turn up, in which respect the _terpen_ resemble the Scottish and Irish crannogs. _Clay Objects._--Perforated loom-weights, both conical and flat; spindle-whorls in great numbers, and often ornamented with finger marks or grooved lines (Nos. 2 and 3). Some flat and triangularly-shaped objects of clay (No. 22) are perforated with three holes, one at each angle, which are sometimes perpendicular and sometimes parallel to the surface; in bulk and composition they correspond with the loom-weights. _Pottery._--Pottery is, as a rule, coarse but abundant, and represents vessels of various shapes and sizes, generally with ears, but a few with handles (Nos. 20 and 23). Samian ware is represented by many fragments of bowls and dishes. A few vases, apparently home-made, have some traces of coloured patches; and there are lids with raised handles and ornamented with hollowed dots. _Bone and Horn._--Bone and horn implements are very abundant, consisting of combs (Nos. 1 and 16 to 19) of varied forms, and constructed of plates riveted together with iron rivets, and ornamented with consecutive circles, lines, dots, and curvilinear figures; among them are also a few combs with very long teeth (No. 30).[68] There are also pins (Nos. 26 and 28), needles (No. 29), buttons (No. 25), dice (No. 21), finger rings (No. 12), knife handles, pointers, etc. (Nos. 10, 11, 13 and 27). Many so-called skates made from the long bone of the horse's leg. Two or three short bones (foot of the ox) are covered with concentric circles, apparently for ornamentation. A curious bone object (No. 7) is supposed to have been used in making twine or ropes. [Illustration: =Fig. 100.=--TERPEN. Nos. 24 = ⅙, 12, 21, 27, and 29 = ⅔, and the rest = ⅓ real size.] _Glass._--Beads, blue, green and variegated; also glass slag. _Metal Objects._--A few bronze dishes (No. 5), one a tripod with projecting handle (No. 15). Figurines of men and animals; the hand of a Roman statue, apparently a female and about full size; Roman fibulæ; some three or four double spirals; a small pair of shears (No. 8), and a few bracelets with clasping-hooks. All these are of bronze. Among objects of iron are shears, hammers, bridle-bits (=Fig. 101=), slag, etc. A leaden bar or pig weighing 17 kilogrammes and marked with three crosses, so, "XXX", was found at Achlum. _Coins._--Anglo-Saxon coins very abundant: at Hallum 180 _sceattæ_ were found in a jar; Byzantine money in gold; Roman imperial money, generally in silver, but sometimes in gold; Frankish coins. The proprietors of Aalzum found a few silver coins in this terp with the following inscription: "+ HLOTHARIVS. IMP. DORE STATVS MON (_eta_)," which defines their date to be between 840 and 855 A.D.[69] [Illustration: =Fig. 101.=--TERPEN. Iron Bridle-bit, ¼ real size.]
