Fig. 108. Scallop Dredge, 'The Scraper." - This implement has the 

 form of a triangular iron framework, with a curve of nearly 90 at the base, to form 

 the bowl of the dredge. On the upper side a raised crossbar connects the two arms, 

 while at the bottom a strip of iron 2 inches wide extends across the dredge. This 

 narrow strip acts as a scraping blade, and is set at an angle so as to dig into the 

 soil. The top of the net is fastened to the crossbar and the lower part to the blade. 

 The usual dimensions of the dredge are: arms, I' 1 -j t'crt; upper crossbar, 2 feet; 

 blade, 2 1 /:" feet. The net varies in size, usually running from 2 to 3 feet in length 

 and holding between 1 and 2 bushels. Additional weights can be put on the cross- 

 bar when the scalloper desires the dredge to "scrape" deeper. A wooden bar 2 

 feet long buoys the net. The scraper used at Nantucket has the entire net made of 

 twine, whereas in other localities the lower part consists of interwoven iron rings.
