81() ASHLEY — GEOLOGY OF ARKANSAS. [May 13, 



the Ouachita river. Kirby, Gentry, Star-of-the-West, New Hope 

 and other settlements lie through the centre of this valley. 



To the north of this belt the Brushy Branch anticlinal axis 

 exposes shales and produces a low and well-inhabited area. 



The Galena and Little Possum creek anticlines in like manner are 

 not productive of strong topographic features and are well under 

 cultivation. 



Water Poiver. — Most of the larger streams carry some water all 

 the year round. In the eastern part, however, the larger streams 

 present but few opportunities for obtaining water power ; though in 

 a few places, as on the Caddo, where the stream makes a long and 

 close bend or horseshoe, power might be obtained by carrying 

 water over the neck at some narrow place. 



In the western part the streams have more fall and opportunities 

 for obtaining power are frequent. Many small mills and cotton 

 gins exist there already. In many places the topography is such as 

 to render the building of dams of twenty or thirty feet height, a 

 comparatively simple problem. There are no falls of mo/e than 

 a few feet, unless the Falls of the Cossatot be counted such (the 

 stream here drops between twenty and thirty feet by a series of 

 small jumps in a space of less than a quarter of a mile), but in many 

 places where ridges are cut through, the channel is narrow, giving 

 facilities for building dams, while the fall is so rapid that but little 

 land would be flooded by back water. 



With the utilization of such cheap power there is no reason why 

 cotton and other products, instead of going south to the railroads 

 and then north to the mills, should not here be converted into cloth 

 and other manufactured products. 



Mifiera! Springs. — Several mineral springs have become quite 

 well and favorably known as summer watering places for people 

 from south Arkansas, Louisiana and Texas. The best known of 

 these are : 



Mineral Springs in 8 S., 22 W., section 18. 



Jenkins' Springs in 6 S., 26 W., section 34. 



Baker's Springs in 5 S., 30 W., section 14. 



Gillam Springs in 4 S., 30 W., section 22. 



Tyra Springs in 5 S., 32 W., section 2. 



Bog Springs in 5 S., 32 W., section 10. 



All of these springs are pleasantly located. At the present time 

 the Mineral Springs in Clark county and Jenkins' Springs are the
