A well-formed globe of gritty sandstone. The surface is rough- 

 ened or granular. It is 2J inches in diameter. 



Portion of an oblong hammer stone, 1 inches in length by 3 in 

 diameter in the middle part. One end has been much re- 

 duced by use. It is made of some dark, much decomposed, 

 crystalline rock. 

 62768. Asymmetrical sandstone ring, 2 inches in diameter and three- 

 fourths of an inch in thickness. The perforation is about 

 five-eighths of an inch in diameter. The surface is rough-

 is 4| inches m diameter and 1^ inches in thickness at the 

 circumference, and less than 1 inch thick at the center. 



6286!). An hour-glass shaped tube made of gray hydro-mica schist, 

 which resembles very compact steatite. It is 5i inches long, 

 2 inches in diameter at the widest part and 1 J inches at the 

 narrowest part. The most restricted part near the middle 

 is girdled by a ridge or ring, on the circumference of which 

 seventy or eighty shallow notches have been cut. 



The perforation is much enlarged at the ends, giving cup- 

 like cavities. The walls are thin near the ends and quite 

 thick near the middle, the passage being hardly more than 

 one-quarter of an inch in diameter. The markings on the 

 inside indicate that the excavation has been made by a goug- 

 ing process, rather than by the use of a rotary perforator.
