BULLETIN OF THE UNITED STATES FISH COMMISSION. 
deep holes were muddy, the spaces between them rocky and gravelly. A small 
bayou near the river was also seined. It yielded only Notemigomis and Ameiurus 
in abundance. The river is fed by a few small streams only. The waters were muddy 
in consequence of the rain preceding and during our visit. The temperature was 
77° Fah. 
The Niangua Eiver near Marshfield, Mo., is a stream of very clear water flow- 
ing over a sandy and gravelly bottom. When we visited it the water was low, 
and in many places the stream was not more than 20 feet wide. The Mangua is fed 
by numerous quite large springs found ali along its course. This stream is quite re- 
markable for the bright colors of its minnows and darters. A great number of JEthe- 
ostoma coendeum spectahile were taken from a sort of bayou with a sandy and muddy 
bottom. The temj)erature of the Niangua was 76° Fah. The Pomme de Terre Eiver 
rises near Marshfield, Mo. It is some 10 miles distant. We were told that during the 
summer it runs nearly dry, and that it was in this condition when we were there. 
Owing to these facts we did not visit it. 
The Sac River near Springfield is not large, and the water is not very clear. The 
bottom has mud, some sand and gravel, and the current is rather sluggish. It is 
much smaller than the James, and according to the iieople of Springfield it bears no 
comparison to the James for fishing purposes, although the James is said to be quite 
depleted of its game fishes. The temperature of the Sac was 79° Fah.
