22 BOTANICAL. INFORMATION. 



as we were occupied in preparing some eland's flesh for 

 supper, the unlucky animal contrived to get loose, and darting 

 off in the dark, effected an escape after five or six days' 

 captivity, and though we pursued her track for several hours, 

 it was all in vain.

Notes on the Vegetation and general character of the 

 Missouri and Oregon Territories, made during a 

 Botanical Journey in the State of Missouri, and across the 

 South Pass of the Rocky Mountains, to the Pacific, 

 during the years 1843 and 1844 j by Charles A. Geyer.

IV. — The Sandy Desert Region comprises the eastern 

 portions of the Sierra Verra, Sierra de los Grallos, and Sierra 

 de las Mimbras. Like the preceding saline barren region, 

 this is without any limits, but is partly intersected by 

 spurs of the Rocky Mountains, by saline barren lands, or, the 

 least part of it, by subfertile gravelly plains or ridges. About 

 one- half of Missouri and Oregon territories belongs to this 

 region, as well as one third, or one-fourth, of the State of 

 Arkansas ; its boundaries westward pretty well keep the same 

 lines with the Saline region, but it diverges out of those 

 limits eastward, reappearing in the territories Dacotah, Iowa, 

 Wisconsin, and the northern part of Illinois to Lake Michi- 

 gan. Most part of this eastern prolongation does not belong 

 to what may be properly termed desert, but rather Poplar, 

 Oak, or Pine barrens. These, as well as the other great half 

 of this region, on the west of the Rocky Mountains, will be 

 described later, under separate heads. 



The apparent geological features will be noticed separately, 

 since, on account of the different altitudes, this region must 

 be again divided into four sub-regions. 



General character of the vegetation.— Westward, fronting 

 and encompassing part of the great region of the Conifers !
