sions, 8 x 4 x 3 cms. The stone is not perfectly cylindrical 

 and the flattening may have been intentional for convenience 

 in holding. 



Figure 6. Large stone hammer, with rounded butt, and 

 broad, flattened cutting-edge. This specimen appears to 

 agree very closely with the one found by S. Couling near Tsing- 

 chou Fu in Shantung and figured by B. Laufer l Three parts 

 of the hammer are perfectly cylindrical, after this the sloping 

 off which produces the flattened edge commences, rather 

 lower down on one face then the other. All corners and edges 

 are bevelled off. Dimensions, total length— 16 cms., breadth 

 5*5 cms., greatest width across flattened cutting edge — 1*5 cms. 

 The hammer is fashioned from a coarse diorite and has been 

 excellently polished. Purchased in Lao-niu-kai. 



Figure 7. Stone hammer, of the same general type as 

 figure 6 with the following minor differences. An oval instead 

 of a cylindrical section, and more symmetry in the angles be- 

 tween the faces and the flattened edge. The latter is worn and 

 broken. The sloping of the faces to the edge commences 

 from one quarter to one half of the total length of the stone 

 from the butt, so that the general appearance of the hammer 

 is more wedge-shaped. It is made from a coarse diorite and is 

 well polished. Dimensions, length — 1T5 cms., width across 

 edge — 6 cms., shorter axis of oval section — 4*5 cms. Purchased 

 in Lao-niu-kai. 



Figure 8. Stone hammer, very similar to figure 7. The 

 section is still more ovoid, and the sides have more tendency to 

 taper to the rounded butt. The specimen is damaged near the 

 butt and the edge, though sufficient of the latter remains to 

 show that it was intentionally flattened as in the previous two 

 examples. Fashioned from a basaltic rock and polished. 

 Dimensions, length — 12*5 cms., longer axis of oval — 6 cms., 

 shorter axis — 4*5 cms. Purchased in Mi-chih. 



Figure 9. This broken hammer from Mi-chih exhibits a 

 more strongly arched edge, sharper than that in any of the 

 preceding examples. It is ovoid in section. The butt is 

 entirely missing. Dimensions, breadth across top of edge — 6 

 cms., length of short axis of sectional oval— 5 cms. Material, 

 a coarse dolerite? 



Figure 10. In this form we have a transition from the 

 cylindrical or slightly ovoid stone hammers with broad rounded 

 butts, flattened edges and more or less parallel sides, to the 

 commoner, polished stone, axe-like celts, with smaller, more 

 pointed butts, sharper edges and more tapering sides, the type 

 in fact which is so prevalent in Indian Neolithic finds.
