Prof. Morse who is the first discoverer of a mound of this character in the 

 Empire of Japan lias pointed out the following characters in regard to the Omori 

 deposit : — " The Omori deposits are also specialized. First : by the presence of 

 enormous quantities of pottery of many different shapes, and of an almost infinite 

 variety of ornamentation. Second : by great scarcity of stone implements, and 

 the absence of arrow heads, spear points and other pointed implements of stone. 

 Not a single arrow head, flake or chip has been found by the various parties who

POTTERY. 



Many earthern vessels, and fragments of potteries were collected in the 

 Okadaira deposit of Hitachi. The vessels are mainly composed of rough 

 materials, and some of their shapes are extraordinarily curious. The pottery is 

 generally thicker than that of the Omori deposit, and mostly ornamented with 

 various designs, plain or unornamented pottery being comparatively rare. 



Knobs are generally of large size, and of diversified form. The dimension
