Almost in the centre of the Great Basin there is a veritable oasis. 

 At the base of a long hill of considerable height there is a cluster of 

 springs known as Iron Springs, from the peculiar taste of the water. 

 The entire hill seems to be made of better soil than the surrounding 

 country, for it is covered with a fine growth of grass, including many 

 of the best species, as Boutelua racemosa, Andropogon furcatus. A. 

 nutans, A. hallii and Panicum virgatum. Here we ah- ■ f und En ■ .,ti«
