REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



the northern current that sweeps arouud the outside of Gape Cod and 

 No Man's Land and into Fisher's Sound, the temperature inshore ranges 

 from 61° to 70° ; more offshore, it ranges from 00° to G4°. But in the 

 colder water about Cox's Ledge and off Block Island and in certain 

 parts of Fisber's Sound, it ranges from 45° to about 50°. 



At Portland there is quite a different condition. The maximum tem- 

 perature was observed inside of Caseo Bay, where the range was from 

 57° to 65°, and outside from 50° to 59°. The bottom temperatures dur- 

 ing the summer inshore were from 54° to 5C°, and in the deeper waters 

 of Casco Bay from 45° to 49°. Farther east and in the Bay of Fundy 

 still lower degrees are shown. 



The following table of temperatures actually observed along the coast 

 at different times of year will be of interest. It is compiled from ob. 

 servations made by the U. S. Signal Service as a matter of special co- 

 operation with the work of the U. S. Fish Commission. 



Absolute highest and lowest temperature of water at the bottom at 3 p. m. during the year 



ending February 28, 1877.
