Both in Kansas and Nebraska the precipitation increases rapidly 

 from west to east, which is contrary to the usual rule of greater 

 precipitation with greater elevation. Table 2 shows this for a num- 

 ber of stations in or adjacent to the sand-hill regions.

While the precipitation in Kansas is just about equal to that of 

 points in Nebraska corresponding in longitude, it is important to 

 remember that the same amount is less effective in Kansas because 

 of the much higher rate of evaporation. The evaporation at Dodge, 

 Kans., for example, was 54.6 inches per annum, while for the same 

 period at North Platte, Nebr., it was only 41.3 inches per annum. 



While the precipitation in none of the sand-hill regions is great, 

 and varies much from year to year as well as from month to month, 

 the lowest quantity ever recorded at Dodge, Kans., 5 10.1 inches in 



6 During a period of 33 years in which the drought period of the nineties is included.
