BULLETIN OF THE UNITED STATES FISH COMMISSION. 333 



cau get, and sincerely hope you may be able to visit and give us such 

 advice and instruction as may seem best to you after examination of 

 our grounds and work. 



We may add that tlie oyster industry in these waters is rapidly be- 

 coming very large. It is claimed that there have been this season over 

 500,000 bushels of seed from the Chesapeake planted here. It seems to 

 me that much may be done here towards raising our own seed. Thus far 

 the shells which we planted early in this month do not appear to show 

 any " set" of spawn, though they still remain pretty clean and free from 

 muddy deposit. 



If you can favor us with a visit, we shall be most happy to be initiated 

 fully into your views and methods and do all in our power to assist you 

 in your experiments.

By TF. FI^N. 



The following contribution towards the solution of this interesting 

 problem has been communicated to the editor of the Norwegian Journal 

 of Fisberies : 



About the end of May several barrels of salt " great herring" from Lof- 

 foden were received in Bergen. These fish had been caught during the 

 tirst half of the month, and the person who received them forwarded 

 some specimens to the editor for the jjurpose of investigation. The 

 specimens which were examined showed the following dimensions : 



No, 1. Spawner 

 No. 2. Milter ,.. 



Ko. 3. Milter 



No. 4. Sijawiier

* About 25 millimeters make 1 inch. 



These herring were, therefore, of the same size as large spring her- 

 ring and Iceland herring, or as the former so-called " great herriug." 

 The examination of the sexual organs showed the following results : 



No. 1. Spawner 

 No. 2. Milter... 

 No. 3. Milter ..
