England coast, and is still extant in Newfoundland. The dogfish livers 
are richest in fat during vSepteniber and October, and the oil is extracted 
by "sun-trying" instead of by the usual l:)oiling method, the livers being 
allowed to .stand in o})en vats of water until the\' have macerated, when 
the oil is .skimmed from the surface. The skin of this shark, becau.se of 
its fine, hard denticles, is of value in certain crafts, such as poli.shing 
metals. The United States Government has recentl>- investigated the 
various commercial ]>o.ssibilities of the spined dogfish. .Speaking before 
the American Fisheries Society in 191 1, Dr. George \V. Field, Ma.s.sa- 
chu.setts state conimi.ssioner of fi.sh and game, .said: "The matter of 
the utilization of dogfish depends on the question of bringing them into 
port. Fishermen refu.se to bring them in at present. We are now 
endeavoring to make a market by which the fishermen can bring the fish 
to definite places for utilization. But this is difficult, for no manufacturer 
will equi]) a ])lant until assured of a definite supply of dogfish."
