Kow the third column of this table shews, not only that the in- 

 creased rainfall of the protected forest region has been on the whole 

 progressive since 1876 (the year after protection was systematically 

 enforced), but that its progression has been commensurate with the 

 increase of the decennial average shewn in the previous table ; a very 

 important point. As compared with the general average of the pe- 

 riod antecedent to 1875, a rainfall of 48 inches, in integral figures i 

 had risen to 58 inches in 1883, an increase of more than 20 per cent. 

 Whether this increase will be sustained at its full amount by the results 

 of future years is, however, very questionable. The rainfall of 1884 was 

 extraordinarily high, and whereas, as may be observed in the graphic 

 representation of these changes, the rainfall of the Central Provinces 

 rises and falls pari passu with that of the whole of India in a somewhat 

 remarkable degree (having regard to the comparative smallness of 

 its area), the progressive average rainfall of India as a whole for 1883 

 was nearly 3 per cent, above the general average between 1867 and 1875. 

 But after making all due allowances, in so far as any legitimate con- 

 clusion can be drawn from the experience of the last ten years, it would 

 seem that, owing to some local cause, the mean rainfall of the afforested 

 region of the Central Provinces here considered, an area of nearly
