INDIAN STONE IMPLEMENTS. 485 
ments buried in the ground ; such deposits simply prove that 
the aborigines having cut out rough outlines of implements, 
at times carried these to their camping ground, and there 
buried them, to be finished at leisure. I exhibit specimens 
of a lot that I dug up in Marblehead, on the Freeto farm, 
about a foot below the surface; such deposits are called 
"Indian pockets." There were over forty pieces in the lot. 
Here is one of a lot of nearly a peck, found in Hadley, 
Mass. The quantity in every case appeared in each instance 
to be about equal, apparently limited by the weight one per- 
son might conveniently carry. From a study of the break- 
age we learn that in making their arrowheads and toma- 
hawk points they chipped the stone from the edge towards 
the centre, which, while it gave a sharp edge, left a central 
ridge that gave strength to the weapon. In finishing arrow- 
heads there was a great deal of slow, careful work, which 
finally consisted in breaking off particles almost as fine as 
dust, by gentle pressure against stone. I had one arrow- 
head brought to me by a friend from California, made from 
the bottom of a glass bottle; it was very sharp and exquis- 
itely finished. It was mostly made in his presence by an 
Indian squaw and nearly three days were spent in its manu- 
facture. It can be safely stated that with the same tools no 
white man can make an Indian arrowhead; I am informed 
that even Flint Jack, skilled as he was in the business, after 
many years of practice, failed in his “Celts,” as stone arrow- 
heads are ealled in England. 
From the very few arrowheads made from red jasper, 
found in Marblehead, I doubt whether the fine ledge of jas- 
per loeated in Saugus, about five miles distant, was known 
to the aborigines, as the rich color of the stone, with its fine 
conchoidal fracture, would have been likely to have made it 
very popular. The material for the few arrowheads found, 
made of red jasper, I presume was procured from rocks of 
the drift deposit. The rocks used by the Indians on the 
coast in the manufacture of their larger implements, such as
