1855.] Notes on Northern Cachar. 683 



vegetation or the cultivation in the district, both of which are 

 luxuriant ; I cannot, therefore, think that there has been any great 

 deficiency in moisture. 



Apaloo is situated on the spur of a hill on the northern face of 

 an extensive range of mountains, called the Burrail, running east and 

 west between the rivers Brahmaputra and Soorma. Three attempts 

 at approximating to the height, by ascertaining the boiling point of 

 water, give the following results : — 



1st Temp, of air 80°. Boiling point 209°. Height 1687 feet. 



2nd ditto 84 ditto 208f ditto 1836 ditto. 



3rd ditto 77 ditto 209£ ditto 1537 ditto, 



the mean of which is 1686 feet. 



The spur, on which the station is built, runs down from a large 

 hill towering some thousand feet immediately above the place to 

 the S. E. On the S. W. rises a large mountain some 5000 feet in 

 height, and distant only about three or four miles from Apaloo. 

 Between these two mountains, and (to within a degree) directly 

 south of the station lies a gorge, or valley, the crown or head of 

 which is 2376 feet above the level of the sea, and through which, the 

 prevailing wind precipitates itself on the station. The direction of 

 the wind, however, from the local circumstance of the ridge above 

 Apaloo presenting itself as a barrier, is not as might be supposed 

 due south, but almost exactly S. E., the superior ridge having the 

 effect of turning the current in an easterly direction. 



Due east there is another gorge between the Apaloo mountain, 

 and the one adjacent to it on the north ; through this however, the 

 winds are infrequent. The site of Apaloo overlooks the northern 

 and western sides, the winds from those directions are therefore not 

 acted upon by any local agency. 



In this register, I have given seven places of force to the wind, 

 and as I had no other means of determining these, otherwise than 

 by the resistance of my own person, and neighbouring objects, I 

 preferred naming them by terms significant in themselves, rather 

 than by employing numbers, which would require experience to be 

 properly appreciated.
