For two years we met at the appointed hour and together gave the 

 lessons, some 125 in all, in twelve schools. Miss Crocker was 

 not only critical and suggestive in our discussion of the lesson, 

 but while she wrote on the board the children's answers to my 

 questions, she supplemented and modified my work in a marked

 From many quarters she gathered ideas on special topics, selecting 

 and combining whatever could be made of use into an harmonious 

 whole for the use of the public schools.

 importance has been undertaken in Boston since 1871, without 

 Miss Crocker's interest and counsel. 



"We have lost not onty a friend, but an inspiration." 



It was voted that the Secretary express to Miss Crocker's fam- 

 ily the Society's sympathy in their bereavement.

LOCALITIES OF QUARRIES WORKED BY THE INDIANS 

 FOR MATERIAL FOR THEIR STONE IMPLEMENTS. 



BY HENRY W. HAYNES. 



For some time past I have occasionally found in different Indian 

 shell-heaps and village-sites along the north shore of Massachusetts 

 Bay, implements and flakes made of a compact, unicolored felsite, 

 of a light green color. It has been a matter of some interest to 

 me to discover, if possible, the locality from which this handsome 

 material was obtained. No specimens of it are to be found in our 

 own mineralogical collection, and there are none at Cambridge ; 

 and our local mineralogists could not give me any clew to it. Last 

 summer, however, I succeeded in finding a spot where it occurs in 

 large quantities, and where manifest traces appear of its havino* 

 been extensive^ worked in former times. The soil in the imme- 

 diate vicinity is filled with chips and broken fragments, many of 

 which, by their disintegrated condition and weathering, show marks 

 of great antiquity. The locality is a hill in Melrose, about a quar-
