the crown. That this action of the forests is felt at distances from the forests is 

 another important point in the chain of evidence proving the indirect value of for- 

 ests, for it means that districts possessing a high percentage of forests have a 

 more equable climate than those possessing a low percentage or no forests at all. 

 A most interesting research was made in Europe to investigate this very matter. 

 A belt of country right through Europe along the 46th parallel of latitude, from 

 La Rochelle in France to the mouth of the Volga in Russia, was examined, and it 

 was found that, wherever there were large areas of forest, the extremes of tem- 

 perature were not so marked, while over regions where the forests had been des- 

 troyed or where no forests existed, the extremes were very great. Work done in 

 India has shown the same results, only the actual figures were more remarkable. 

 In Assam, for instance, it was found that the mean temperature in July within 

 the forests was 36.5° centigrade, while in the country Avhere the forests had been 

 destroyed, though the latter region is situated nearer the sea-board, it was 57.4° 

 centigrade.
