COLORADO TOPOGRAPHY. 
to obtain specimens of those animals which fre- 
quent the wilder regions, and some of her attempts 
to accomplish this end will be given in the next 
section. 
Colorado is composed of two regions, as dif- 
^ ferent from each other as we can imagine 
two worlds may be. 
The one region has thousands of square miles 
where hardly a tree or a large rock can be found ; 
the other similar areas where it would be hard to 
find anything else. The one gives the eye only 
endless monotony ; the other affords almost limit- 
less variety, both in surface, productions, and 
climate. 
The plains, which cover about half the State, 
are not at all like anything in New England, or 
any of the Eastern States. They are very different 
from the great prairies of Illinois and southern 
Wisconsin. In fact, they have a strong individ- 
uality, which cannot be put in words. 
Though they are far from being level, they 
sweep with a broad, clean look, as though they 
had been rolled and prepared for lawns, up to the 
very foot of the mountains. 
In Colorado there are shown no such hesitat- 
ing attempts at making elevation as are mani- 
fested in the formation of Eastern mountains.
