Chap. XXVII. CHINCHONA SITES. 465 



I reluctantly came to the conclusion that the Mahaba- 

 leshvvur hills were not well suited for the growth of chinchona- 

 plants. The intense dryness of the atmosphere during the 

 greater part of the year, the poor character of the vegetation, 

 and even the enormous rainfall during the summer months, 

 which more resembles the climatic conditions of the forests of 

 Canelos to the eastward, than the region of " red-bark " trees 

 to the westward of Chimborazo, all pointed to this conclusion. 

 Nevertheless some seeds of chinchona-plants were forwarded 

 to Mr. Dalzell, the Conservator of forests in the Bombay 

 Presidency, which are said to have come up well at Mahaba- 

 leshwur. If these plants should really tlirive it will prove 

 that they are capable of adapting themselves to differences of 

 climate to an extent of which we previously had no idea. I 

 sincerely trust that this may be the case, and that some 

 at least of the species of Chinchona3 now in India may be 

 successfully introduced into the Mahabaleshwur hills. Mv. 

 Dalzell informs me that there are high hills to the eastward 

 of the Portuguese settlement of Goa, but not so elevated as 

 Mahabaleshwur, where he thinks that some of the Chinchonae, 

 which flourish at low elevations, might be acclimatized. He 

 had observed that, in the Bombay Presidency, a difference of 

 150 to 200 miles southing is equivalent to a certain elevation,
