and part of Ellis county, however, its channel is deep enough to 
reach the Tertiary waters, and it is constantly supplied with seeps 
and springs, so that never failing water occurs throughout almost 
all the remainder of its course. | 
The valley of the Saline in the western part of the state is narrow, 
practically amounting to nothing. Eastward in Ellis county the 
valley widens to a mile or more, while below it gradually widens to 
from two to four miles. 
The bluff lines of the Saline are almost inconspicuous at its im- 
mediate source. But a short distance is passed, however, until 
the channel has reached a depth of from 20 to 40 feet, a depth which 
eradually increases eastward until the Cretaceous formations are 
reached in Ellis and Russell counties, where the bluffs frequently 
are 100 feet or more in hight. Below these localities the bluffs 
maintain their great hight. In the vicinity of Salina the Dakota 
hills some distance back from the stream rise nearly 200 feet from 
the level of the water in the Saline. 
There are no features of this stream which are in any way dif- 
ferent from the ordinary. It is remarkably straight in its course, 
has worn a valley through the lower part of its length commen- 
surate with the valleys of other streams in the state, and has a 
depth of channel about the same as those of other streams in this 
part of the state. 
Solomon .River. 
This river rises in the northwestern part of the state in Sherman 
and Thomas counties. From here to Downs in Osborne county there 
are two forks, the north and the south. These two branches rise 
within less than ten miles of each other, but separate in Graham 
and Rooks counties to a distance of about twenty five miles. In 
the upper part of their course each stream is very like the Saline 
river, so much so indeed that little can be said of one which is not 
applicable to the other. As they pass eastward their channels grad- 
ually become deeper and their valleys wider. At Stockton in 
Rooks county the valley of the South fork is about a mile wide, while 
at Marvin, immediately north, in Phillips county, the North fork 
has a valley of about the same width. In this area the high upland
