representing one of them (fig. 2) in advance of its appear- 

 ance in his work on the "Stone Age in New Jersey," for 

 the purpose of showing its great resemblance to the speci- 

 mens from Essex County, of which there are two in the 

 Academy Museum. The one represented here as figure 

 1 is the more beautifully finished and perfect of the two. 

 It was found in Salem and placed in the Museum of the 

 East India Marine Society. It is not quite five inches 

 in length and is a little less than two inches in greatest 

 depth of blade and back. The back is about half an 

 inch in depth and a little over a quarter of an inch in 

 width at the centre ; narrowing at the ends ; perfectly 

 flat above. The blade is one-fifth of an inch thick along 

 the under side of the thick back ; it is gradually 'thinned 

 out to the cutting edge all round, which is only one- 

 tenth of an inch thick about one-fifth of an inch from 

 its outer margin, which is evenly and nicely brought to a 

 sharp cutting edge. The engraving shows the shape of 

 the knife better than words will describe it. It will be 

 noticed that the blade is slightly more pointed at one ex- 

 treme than at the other. The material is a gray slate 

 having several fine veins of a harder substance (quartz?) 

 as shown in the engraving ; it is quite ornamented with 

 several dark wavy lines, light streaks and bands, and a 

 number of irregular wavy lines of a red mineral running 

 in all directions over the surface, but not indicated in 

 the engraving. 



Another specimen, also received by the Academy from 

 the East India Marine Society Museum, was found on the 

 farm in Danvers formerly owned by Governor Endicott. 

 This specimen consists of about one-half of the kitife, 

 and was evidently, when perfect, about six inches long 

 and two and a quarter deep. It was made of a slate very 

 much like the Salem specimen, but without the dark and 

 red veins and mottlings.
