 Freipient in the .nlkaline valleys of the Great Basin, from the Sierra Nevada eastward to the 

 Upper Missouri and the headwaters of the Platte and Canadian, .and southward to the Gila ; 

 tlie most prevalent of the several shrubs bearing the name of " Grease- wood." The wood 

 is very compact and hard, of a light yellow color, but the stems i-arely exceed 2 or 3 inches in 

 diameter, and are usually knotted'and twisted ; the bush, however, though small is valuable for 

 liiel, and often the only resource.
