perforation which is about seven-sixteenths of an inch in depth. 

 The weight of this stone is 16*4 ounces. The wings are not uni- 

 form in length, there being a difference of more than one-fourth 

 of an inch in length. The twist of the wings, right and left, is 

 also apparent in this specimen. 



A narrower specimen of unfinished banner stone (M-2419) was 

 found at Arius lake, Rensselaer county. The specimen is 6^4 

 inches in length and weighs 15^2 ounces, the width through the 

 centrum being ij4 inches. The perforation has been started and 

 the drill core projects from the drilling, which is about three- 

 sixteenths of an inch in depth. There is a groove on the upper or 

 outer side of the specimen which appears to have been slightly 

 polished, but the general surface of the stone has been scoured only 

 enough to remove the deeper pitting. One of the lower corners 

 has a chip taken out which shows the material to be an impure 

 marble quartz. 



A fine specimen of unfinished sandstone banner stone from 

 Atwood, Perth county, Ontario, Canada, is in the Museum col- 

 lection and is interesting for the purpose of comparison. A twist 

 in the wings of this specimen is also evident. The bulbous centrum 

 is flattened on each side and drilling has proceeded about two- 

 thirds the diametrical length of the centrum. A broken core shows 

 as a break at the bottom. 



Specimen M-21591 is an unfinished granite banner stone with 

 the drilling at the expanded portion and carried to the depth of 

 about three-eighths of an inch. This specimen shows drilling by 

 tubular perforation. The indented and in-sloping top of the stone 

 has a rather high polish, but the under side has been only roughly 

 picked and ground into shape, though there is an indentation in 

 which the perforation was to be made. 



A very interesting specimen of a dark drab slate banner stone 

 (Y-29632) comes from the Hudson valley in Orange county. This 

 specimen has been undoubtedly finished, though the perforation is 

 only about one-half the depth of the centrum. The centrum is 

 like a pipe bowl, fifteen-sixteenths of an inch in diameter. The 

 lower curve of this centrum is about three-eighths of an inch from 

 the curvilinear line forming the outward circumference of the 

 specimen, but a notch has been cut in the base of the wings meet- 

 ing the bottom of the bowl like centrum. It is not exactly in the 

 center, which makes the wings appear unequal in length by almost 

 one-fourth of an inch. Two tally marks appear at the top of each 

 wing.
