Flora of the Sand Hill Region of Shebidan and Chekey Counties and 



List of Plants Collected on a Journey Through the Sand 



Hills in July and August, 1892, by Jared G. 



Smith and Roscoe Pound. 



On Jul}- 6th we started from Alliance, and between the 6th and 

 8th we traversed on foot the sand hill region of Sheridan and 

 Cherry counties, emerging at Johnstown in Brown county. Prom 

 Johnstown we went to O'Neill, following, at no great distance, the 

 Fremont, Elkhorn, & Missouri Valley railroad. We drove across 

 country from O'Neill to Lincoln, arriving there August 6th. 



The greater part of the collecting was done in the sand hills 

 and in the lake region of Cherry county. 



GENERAL FEATUBE8 OF THE BEGION TRAVERSED. 



The main group of the sand hills of western Nebraska extends 

 from the 103d meridian, midway between the North Platte and 

 the Niobrara, eastward to the 98th meridian. It extends south- 

 ward to the 41st parallel, and has for its northern boundary the 

 Niobrara. In passing into the sand hills from the old lake basin 

 around Alliance there is a perceptible fall. One does not go up, 

 but goes down ; and there is a general slope towards the east, in- 

 dicated by the fact that in the wet valleys the lake or pond is 

 generally at the eastern end. We met with no exception. 



The sand hills are a region free from drainage. The surface 

 water, instead of flowing off in the river channels, collects in the 

 valleys and forms countless lakes or ponds without outlet. The 

 valleys are, as a rule, parallel, and have a general east and west 

 trend. They are not strictly continuous, being separated by low 

 ridges or groups of low hills. But the passage is always easy from 

 one to the next, while getting over the side of the valley is dif- 

 ficult and sometimes well nigh impossible.
