INVESTIGATIONS IN MINNESOTA AND NORTH DAKOTA. 359 
"across the channel, almost to the surface of the water. The stream 
was fished at Powers Ford, 3 miles north of the town, where the mud in 
the bed of the stream gave place to a bed of gravel and the banks were 
_of sufficient slope to permit the landing of the seine. Temperature of 
_ the water, 81°. 
Jamestown, N. Dak., August 28.—The James River was fished the sec- 
ond time at Jamestown, about 55 miles northeast of La Moure. The 
character of the country is similar to that around La Moure. The hills, 
however, are farther from the river. The soil contains a great many 
more bowlders, but these are mostly small. It is also filled with banks 
of coarse, water-worn gravel, containing clay and iron nodules. The 
river at this point is about 18 to 20 feet wide and from 2 to 3 feet deep. 
The stream is obstructed here by a high dam built for power purposes. 
The collecting was done below the dam, where the stream is composed 
of a series of ripples, and the water runs rapidly over a clean gravelly 
bed. The banks of the stream are composed of drift, covered with 
vegetation that grows to the water’s edge. The banks are also lined 
with a natural growth of small timber, such as box-elder, maple, elm, 
and three varieties of willow. There is a scant water vegetation where 
the stream was examined, which covers the large stones of the bottom. 
A few crawfish were found, and also a few water-snails. The stream 
swarmed with small fishes; Rhinichthys was taken by hundreds; Pime- 
phales, Notropis, and Etheostoma were also well represented. The stream 
at this place is well adapted, to darters and dace, being quite clear 
and cool. The temperature of the water, 60°, would indicate consider- 
able spring water, though no springs were observed. 
Pipestem Creek, Jamestown, N. Dak., July 27.—This is a small western 
tributary of the James River, flowing nearly parallel with, and between, 
the same two ranges of hills. Itis about 50 miles in length, narrow 
and deep. Itis a poor stream in which to make collections, since no 
ripples were to be found. The water is clear; the temperature 62°.
