THE CORRELATIONS OF AREAS OF MATURED CROP AND THE RAINFALL. 369 



The proportions of unirrigated matured crop in the different circles is somewhat 

 different from those of the Kharif harvest. 



They are Bharari 23, Nianda 11, Bet 6, Bajwat b, Charkhri 8, and the average 

 of the 5 years 1887-8 — 1891-2 gives the following proportions of crop for the whole 

 Tahsil.

(a) Kharif. 



The regression equations are : — 



For crop on rain 



C K = 548*21 Rk-It 31,910 

 For rain on crop ; 



C K = 20^4 R K + 238 1 

 and the probable error E c = +1325.
