64 NEW YORK STATE MUSEUM 



near Syracuse is of calcareous tufa, seven inches in outside depth, 

 and four and one half inside. The upper diameters are 11 and n.£, 

 with a diameter of eight inches at the bottom. This has been called 

 a mortar, but is properly a vessel of another kind. One from Ken- 

 daia is a nearly circular pebble, seven and one half inches across, 

 and excavated on both sides. A fine circular one is from Pompey 

 Center, of limestone, and much like the last. It is nine inches in 

 diameter, and the depression is six inches across. Many of these 

 might be described. 



Fig. 159 is a beautiful cup of dark bluish green striped slate, two 

 and three fourths inches across. It was found in Hannibal in 1875, 

 and is unique here, but one has since been added to the Toronto 

 collection, closely resembling this in every way. The form is cir- 

 cular, and the shallow bowl is neatly curved to a point at the base. 

 These two examples add to the other proofs of the close relations of 

 New York and Canada in prehistoric times. 



Most cups are of ruder form, and they are rarely symmetrical. 

 Fig. 160 is one of these, and is of soapstone, with one side raised. 

 It is two and five eighths inches across the long diameter, and 

 comes from the Oneida River, with one of similar form. Fig. 163 

 is a small one found in or near an earthwork in Elbridge, and made 

 of brown sandstone. It is one and one fourth inches wide, and 

 one side is deeper than the other. A paint dish or bowl, four and 

 one fourth inches wide and two deep, comes from the Mohawk 

 River. A small stone ball was in it. There are other examples, but 

 of no special importance. 



DOUBLE-EDGED SLATE KNIVES 



A class of polished slate knives in New York and part of Canada, 

 has long had the local name of slate arrows, and these are but little 

 known to archaeologists in general. They closely resemble but are 

 not generally identical with some of the slate knives of the Point 

 Barrow Eskimo, figured and described in the ninth Report of the 

 Bureau of Ethnology. Those figured in that volume have no barbs, 

 and these are a common but not invariable feature of these New 

 York knives. The grinding and provisions for hafting are identical. 



There are suggestive similarities between several Iroquois articles
