it could not be extricated without using force sufficient to bend 
and twist the stout iron cross-bar; at somewhat greater depths, 
in 20 to 30 fathoms, farther away from the crests of these 
ledges, the bottom was generally stony and gravelly, though 
often rough, and the dredges were used with good success. 
Most of the species from these localities have been enumerated 
in the two preceding lists, and need not be repeated here, but a 
considerable number of additional ones occurred. The roughest 
parts of the ledges, in 10 to 15 fathoms, are overgrown with red 
gee, and among these the reddish variety of cod, known as 
“rock-cod,” abounds. Here also a large number of interesting
