HAWORTH. | Physiography of Western Kansas. Al 
between the two streams is nearly 300 feet above the valley of 
either stream. Farther east the relative hight of the bluffs per- 
haps decreases a little, while the width of the valley correspondingly 
increases. From their junction at Downs to the mouth of the Sol- 
omon the valley will average more than two miles wide, reaching 
more than three miles in different places. This stream has nothing 
remarkable about it, every feature as thus far observed conforming 
to the general characteristics of the western Kansas streams. 
Republican River. 
This stream rises in Colorado opposite the northwest corner of 
Kansas. It flows to the northeast across Cheyenne county, passing 
into Nebraska on the north, through which state it travels 
for about two hundred miles. It again passes back into Kansas 
at the northwest corner of Republic county and flows in a south- 
easterly direction to its junction with the Smoky Hill at Junction 
City, about eighty five miles away. We therefore have but little of 
the stream in Kansas excepting this one space of eighty five miles. 
The upper tributaries which are formed in Cheyenne county are 
small and of but little interest. They lie wholly within the Ter- 
tiary formations, bat have cut channels near to the base of the 
Tertiary, so that the most of them are supplied with living water. 
East from Cheyenne county a number of tributaries pass from Kan- 
sas to the northeast, entering the Republican. These tributaries 
are in most respects similar to the upper tributaries of the different 
streams in western Kansas. The Tertiary formations in the north- 
western part of the state seem to be so thin that the different 
streams have cut their channels almost to the base of the Tertiary, 
so that they draw upon the underground Tertiary water. In this 
way the Republican through the greater part of its course is un- 
usually well supplied with water, but few places being known from 
Cheyenne county to Junction City where water is not available in 
greater or less quantity throughout the year. 
From Republic county to Geary the stream has a wide valley or 
flood plain with prominent bluffs on either side. The valley will 
average more than two miles wide through this distance and the 
bluffs are from 100 to 150 feet in height.
