it difficult to work. Probably the oldest of these, adzes is No. 5GG75 

 [09], Fig. 130, which has been selected as the type of the earliest form 

 we have represented in the collection. This is of dark olive green, 

 almost black, jade, 7-2 inches long, -i-8 wide, and 1-. ? thick, and smoothly 

 ground on the broader faces. The cutting edge is much broken from 

 long use. One broad face is pretty smoothly ground, but left rough at the 

 butt end. The other is rather natter, but more than half of it is irregu 

 larly concave, the natural inequalities being hardly touched by grinding. 

 Like the other dark-colored jade tools, this specimen is very much 

 lighter on a freshly fractured surface. The dark color is believed to be 

 due to long contact with greasy substances.

No. 89002 [900], from Nuwuk, is an exceedingly rough adz of similar 

 shape, but so slightly ground that it is probably one that was laid aside 

 unfinished. From the battered appearace of the ends it seems to have 

 been used for a hammer. It is of the same dark jude as the preceding. 

 No. 89(589 [792], from Utkiavwlfi, is of rather light olive, opaque jade 

 and a trifle better finished than the type, while No. 89001 [1155], Fig. 

 l. Jl, also from I tkiavwin, is a still better piece of workmanship, the 

 curve of the faces to the cutting edge being very graceful. The inter 

 esting point about this specimen is that a straight piece has been cut 

 off from one side by sawing down smoothly from each face almost to the 

 middle and breaking the piece oft . \Ve were informed that this was done 

 to procure rods of jade, for making knife sharpeners. We were informed 

 that these stones were cut in the same way as marble and freestone are 

 cut with us, namely, by sawing with a flat blade of iron and sand and 

 water. A thin lamina of hard bone was probably used before the intro 

 duction of iron. Possibly a reindeer scapula, cut like the one made
