THE DAKOTA OR JAMES RIVER. 
The James River is essentially a prairie stream rising in the south- 
western part of Nelson County, North Dakota, near Devi] Lake, and 
flowing in a general southerly direction for nearly 400 miles before 
joining the Missouri River. It makes its way between a low ridge or 
elevation on the west side and the Plateau du Coteau des Prairies on 
the east. The former separates it from the Missouri, and the latter 
from the Minnesota. It is one of the chief tributaries of the Missouri 
in North Dakota, but its drainage area is much restricted by the eleva- 
tions on either side, and hence the amount of water it discharges is 
re-atively small. The stream was examined at two points, La Moure 
and Jamestown. 
La Moure, N. Dak., July 27.—La Moure is on the Fargo and South- 
western branch of the Northern Pacific Railroad, 100 miles southwest 
of Fargo and over 250 miles from the mouth of the river. Here the 
valley is not more than 10 or 15 miles wide, the hills rising gently 
on either side to a height of about 150 feet. The immediate valley or 
flood-plain of the river is about 2 miles wide, level, and very fertile. 
The width of the stream will not exceed 15 yards, and its depth will 
average 3 or 4 feet. The current is slow, not more than half or three- 
quarters of a mile per hour. The stream is very crooked and has low, 
steep banks. The bed of the stream is of fine mud, several inches deep, 
which is overgrown with a thick mat of pond vegetation, consisting of 
bladderwort, water milfoil, chara, etc., which in places grow entirely
