24 species of Mosses and 156 species of Lichens were collected

Studies were carried on for a period of six years on both 

 semi*arid and humid prairies in Nebraska. The subsoils of the 

 semi-arid prairies were found to be persistently dry, the ratio 

 usually ranging between 1,0 and 1,5. This is attributed to the pre- 

 sence of perennials whose root penetrate to great depths, 15 feet 

 or more. In the subsoils of the humid prairies the ratio in the first 5 

 feet rarely gets as low as 1,2 and deeper than five feet it is usually
