UNUTILIZED FISHES. 49 



authority to act in such a matter, is compelled to await legislation by 

 Congress. During the session of 1906-7 the efforts of the Massachu- 

 setts commissioners and the petitions that poured in from all sections 

 of the coast led to the introduction of a bill providing a bounty of 

 2 cents for every dogfish killed along the coast between Cape Hat- 

 teras and Eastport, Me. The Bureau of Fisheries, however, drafted 

 another bill as substitute for this. (See Report of the Commissioner 

 of Fisheries for 1906.) Instead of the proposed bounty, which was 

 considered undesirable as a precedent as well as inefficient for results, 

 the substitute bill proposes to vote a sum of money to be used in 

 " determining the most effective methods of reducing the numbers of 

 dogfish and of capturing them in wholesale quantities ; in demonstrat- 

 ing the economic value of dogfish as a source of fertilizer, oil, and 

 leather, and the most suitable methods of utilizing them for such pur- 

 poses; and in testing the usefulness of the dogfish as food when used 

 fresh or prepared by salting, smoking, and canning; and in develop- 

 ing the domestic and foreign markets for such preparations." This, 

 it is thought, would afford a practical solution of the problem.
