holes which seem to have been bored slantingly into the slate of which the blade is made, and on the opposite side can be seen two exactly similar marks of drilling alternating with these; this is a feature that is found on eight other slate blades, always at the base, and the intention of these is not clear; it may possibly have something to do with the flaking of the slate.

18–20 belong to a group of implements that is extremely numerously represented, 31 specimens in all, and in addition to these 63 fragments. They are long, symmetrical, two-edged slate blades, ground Image missingFig. 99.Ulo Blade. Belcher Islands. with sharp facets, the base cut square and one to three pairs of notches in the shaft end; the broad forms have apparently been used as lance blades; of the narrow ones some at any rate, on which the central ridge lies rather asymmetrically, have been knife blades, and the same seems to apply to two with broad but sharp points. The specimens not figured vary in length from 6½ to 13 cm; most of them only have one pair of notches. Two specimens have long tangs; one is a thin, two-edged point, 12.3 cm long, the other is an unfinished specimen of a very broad lance head. 21 is a small, single edged slate knife, presumably a toy; eight specimens are fragments of single edged slate knife-blades with almost straight back and curved edge, one has had the handle and blade in one piece. A rather unsymmetrical blade, 16 cm long, 7 cm wide at the middle, is for a large flensing knife like Qilalukan Pl. 47.3, but without the latter's holes. Fig. 99 is an ulo blade of un-usual dimensions: 25 cm long and 44 cm wide, at the top is a short, broad tang for fixing in the handle; the tang, however, bears traces of recent working; five other ulo blades are of the same form but much less in size, 5.7–11.4 cm long; two of them
