rabbit brush of the drier regions is also usually a good 
indication, though it frequently indicates a soil not 
easily handled. Greasewood, shadscale, and other

frequently charged with alkali. Such soils should be 
the last choice for dry-farming purposes, though they 
usually give good satisfaction under systems of irriga- 
tion. If the native cedar or other native trees grow 
in profusion, it is another indication of good dry- 
farm possibilities.
