REPORT OP THE SECRETARY. 75 



ern edge of the Gulf Stream was enormously rich ; of mollusea, not less 

 than 175 different species were taken, forty being new to science. 

 Twenty new deep sea fishes, some of them o^ a remarkable character, 

 were secured. The most important observations, however, were those 

 in regard to the Tile fish {Lopholotilus cliamelconiiceps)^ to which refer- 

 ence was made in a i>revious report. The ascertained range of this fish 

 was greatly extended, showing the possibility of cai)turing it over a 

 wide area. 



For the purpose of determining the ability to take this fish with an 

 ordinary fishing smack a Noank vessel was chartered for the trial. Ow- 

 ing to a threatening storm, however, the vessel was compelled to return, 

 and nothing Avas done beyond thc^capture on a small line of an enor- 

 mous sword-fish. 



Mr. G. Brown Goode, who had represented the United States at the 

 Berlin Exhibition, returning, joined the party on the 17th of July and 

 was, for the most part, occupied in connection with the fishery census. 



During the summer I visited Wood's Holl in the Fish Hawl-, for the 

 purpose of inquiring into the i)ossibility of making a station at that 

 point, for the hatching of codfish. 



The work of the Commission at IsTewport was closed about the begin- 

 ning of October, and on the 7th of that month the Fish HawJc returned 

 to Wilmington for some additional apparatus, carrying a portion of the 

 collection to New Haven, hy the way, for the use of Professor Yerrill. 

 After taking on board further hatching apparatus, the steamer came 

 around to Washington, cruising along the edge of the Gulf Stream on 

 her route, and making additional collections of importance. 



I left Newport with mj' party on the Sth of October, closing operations 

 for the season at that place. 



The control of so well equipped a steamer as the Fish Hmvlc and the 

 several visits to the Gulf Stream resulted in the acquisition of a large 

 amount of material, equal almost to the aggregate of all our preceding- 

 seasons. This has been put in hand and will, as rapidly as possible, be 

 examined, the reserve series added to the collection of the National 

 Museum, and the remainder distributed as heretofore. 



In the Eeport of the Institution for 1S79 reference was made to the 

 operations of the Fish Commission in connection with the artificial propa- 

 gation of codfish at Gloucester, Mass. This work was continued into the 

 beginning of the year 1880 and a large number of fish hatched out and 

 liberated. These have remained for a considerable time in the harbor of 

 Gloucester and its vicinity, and by their abundance and unusual ap- 

 pearance attracted much attention. 



The work of cod hatching was again undertaken in the winter of 18S1, 

 in the little harbor at Wood's Holl, Massachusetts. Facilities were 

 granted by the Light-House Board at its depot ; the machinery was erected 

 and everything in readiness for the w^ork. The unusual severity of the 

 winter, however, which froze up the shores, rendered it impossible to
