Prof. Morse who is the first discoverer of a mound of this chracter in the
Empire of Japan has 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 have been there in the interests of the University ； and the combined time spent there, if represented by a single individual, would equal over eighty days work of seven hours each." These peculiarities exactly agree with the Okadaira
The objects thus far found in the Okadaira mound are enumerated as
1. Cooking vessels
2. Hand vessels.
6. Fragments of pottery possibly used for sinkers.
3. Worked pumice.
4. Stone with circular pit-like depressions
2. Prongs of deer's antlers.

Knobs are generally of large size，and of diversified form. The dimension(#004に続く)
