Among the rivers the Potomac is best provided with observing sta- 
tions, there being one at Fort Washington and another at the city of 
Washington, both operated by the Fish Commission, in addition to 
those above enumerated from Chesapeake Bay. It would add greatly 
to the value of the results if other important rivers could be as well 
supplied. Unfortunately, there are no stations at exposed positions on 
the Pacific coast, where arrangements have yet to be made for the 
study of temperature variations. 
In Section III of the Fisheries and Fishery Industries of the United 
States, published in 1887, the writer presented a first report upon the 
results of observations made at the light stations on the Atlantic coast 
during the years 1881 to 1885, inclusive, the curves of temperature at 
each locality being plotted separately for each year on graphic charts. 
A more complete report, for which all the records down to date are 
being combined, is now in course of preparation. 
The observations above discussed have reference chiefly to the shore 
waters and the rivers, although a few of the light house stations are 
located somewhat off the shore, in exposed positions. The data de- 
rived from those sources can not, therefore, have much bearing upon 
the movements of pelagic fishes until they actually approach the coast. 
It is impracticable to establish permanent temperature stations in the 
open sea at a distance from the land, owing to the depth of water and
