REPORT OF COMMISSIONER OF FISH AND FISHERIES. LIII 



gion than any other species of its family ; but it can only be taken by 

 the beam trawl, the smallness of its mouth preventing- the use of the 

 ordinary baited hook. 



During- the explorations of the summer from Wood's Holl large quan- 

 tities of this species were captured in localities very far to the south of 

 the region where first discovered ; and specimens were sent to Mr. 

 Blackford, at New York, to be submitted to experts and connoisseurs 

 as to their edible qualities. A unanimous approval was given of the 

 fish as being of remarkable excellence, and as in no way inferior to the 

 English sole in its best condition. 



16. — MODELS OF THE FISHING-GROUNDS. 



Professor Hilgard, of the United States Coast Survej^, several years 

 ago kindly undertook the supervision of the construction by Mr. Lln- 

 denkohl of a model to show the fishing banks of the eastern coast of 

 New England, including the Grand Banks of Newfoundland. This con- 

 stituted one of the most interesting American objects at the Berlin Fish- 

 ery Exhibition. 



Desirous of showing some of these banks on a larger scale, a similar 

 arrangement was made with Professor Hilgard for the construction by 

 Mr. Lindenkohl of a model of the Gulf of Maine for exhibition at the 

 London Fisherj^ Exposition. The Coast Survey itself had prepared by 

 Mr. Lindenkohl a model of the entire eastern coast of the United States 

 and the Gulf of Mexico with the special view of showing the depth of the 

 basin of the Gulf Stream as developed by the more recent researches of 

 the Blake. 



It is expected that these several models will be very i)rominent fea- 

 tures of the London Exhibition. 



17.— FUNGUS DISEASES OF FISH. 



The subject of the fungus disease which attacks fish, especially the 

 fresh water salmonidae, is one of great importance, in view of the very 

 serious injury that has been done to the British salmon fishery by this 

 agency. An elaborate report on this subject, made to the British Gov- 

 ernment by Professor Huxley, has been republished by the Commission; 

 but as the conditions in American waters and with American species 

 may be somewhat diflerent. Dr. Farlow has kindly undertaken an in- 

 vestigation of the subject in the interest of the United States Fish Com- 

 mission. As material becomes procurable it will be forwarded to Dr. 

 Farlow for this purpose. 



18. — WORK DONE AT WOOD'S HOLL IN 1882. 



In a preceding part of this report will be found an account of the 

 measures taken to establish, at Wood's Holl, a permanent station for 

 prosecuting investigations into the fisheries, and for the propagation 

 of marine fishes.
