ESTIMATES 



Estimates of the abundance of green crabs and 

 soft-shell clams from the earlj' 1920's to 1951 were 

 obtained from two soiu-ces. First, F. E. Goucher, 

 the Clam Commissioner of Essex, Mass., who dug 

 clams for over 22 years, wrote of his own and other 

 fishermen's observations in northern Massa- 



chusetts.' Second, about 100 coastal wardens and 

 fishermen were interviewed in cooperation with 

 the Maine Department of Sea and Shore Fisheries. 

 Their recollections a]3plied to Maine, but the 

 information reported for southwestern Maine 

 agreed well with that of Goucher (see footnote 1) 

 for northern ^Massachusetts.
