fact that a large proportion of its water comes from the hot springs in 
the Yellowstone National Park. 
Observations begun on April 4, 1890, were continued uninterruptedly 
through succeeding years, being taken on alternate days in 1894, and 
finally discontinued at the end of November, owing to lack of funds. 
The rating table as given below was constructed from gagings made 
during 1890 and verified in subsequent years. It is believed to be fairly 
applicable for 1893, but doubtful for 1894. On August 23, 1893, the 
river was measured from the new iron bridge, about a mile above 
the station, and the discharge was estimated to be 1,189 second-feet. 
Computations of discharge have been made up to the end of June, 
1893, and published in the preceding report, but the measurements 
made since that time indicate such a change in the rating table that 
computations of discharge can not be made with any considerable 
degree of confidence until the position of the gage rod has been veri- 
fied and further check measurements had. This river, as above stated, 
is notable for the slight changes occurring from week to week in vol- 
ume, especially during the fall and winter. Its floods come with extraor- 
dinary regularity, and the steady flow is hardly disturbed by storms. 
The flood of 1894 began, as usual, in the latter part of May, reaching a 
maximum probably of less than 2,500 second-feet, and fell off in the 
latter part of July to the ordinary fall and winter flow of 1,000 to 1,200 
second-feet.
