The prevailing- winds are those of the north-east and south- CHAP. IV, 



west monsoons. The following table, showing the direction of PAliT II. 



the wind, has been compiled from the meteorological observations physical and 



made in the years 1848, 18i9, and 1850 :— Mkdical

The figures under wind, representing the direction of the wind, 

 are reckoned from north towards the east on to 360 degrees, 

 which again represents the north. 



From a perusal of the above table, it will be apparent that. Remarks on 



notwithstandincr the elevation of Doddabetta, it is still situated the above 



^ -11 tables, 



within the stratum of wind and aqueous moisture brought by 



both monsoons; but the comparatively small quantity of rain 



which it receives annually would, however, seem to show that it 



is not situated far below the upper surface of the current of 



aqueous moisture. A peculiarity in the direction of the wind, not 



observed in other parts of India during the prevalence of the 



south-west monsoon, may be seen in the above table. Instead of 



being from the south-west it is almost invariably from points 



between the west and north. This very curious phenomenon is 



doubtless due to some local physical circumstance, in all 



probability the Kiinda hills, which impart a slant to the wind.^ 



The rainfall received upon the plateau is considerably less than Rainfall at
