the foot of the Hills on the southern side, to Raneegaon on 

 the northern side, does not exceed 60 miles ; and that between 

 Churra Punjee and Nunklow, both of which may be said 

 to be on the edge of the higher portion of the plateau, 35 

 miles. 



The heights of the places situated on the route between 

 the above places, are as follows ; they are taken from Capt. 

 Pemberton's "Report on the Eastern Frontier of British 

 India :"

In addition to these places, I must mention Moosmai and 

 Maamloo, near Churra Punjee ; and at about the same eleva- 

 tion, Mumbree between Moflong and Myrung, one of the 

 highest parts on the route ; and the Bogapanee, a mountain 

 stream rushing through a valley perhaps 1,500 feet below 

 Moflong. The mean annual heat of these Hills, although it 

 probably varies much relatively to the distance from the com- 

 mencement of the descent on either side, may be estimated 

 at 65° Fahrenheit, calculating the average height to be 5,100 

 feet, and adopting Baron Humboldt's ratio of a decrease of 

 one degree for every 396 feet of vertical ascent. Very little is 

 known about the climate of the central portions ; but towards 

 either descent, it becomes one of excessive dampness 

 throughout the rains. The southern side receives the 

 whole force of the S. W. monsoon, and the fall of rain at 

 Churra Punjee, the only place where it has been estimated, 

 is, if the accounts be correct, prodigious. Mr. Cracroft 

 states, that the total rain that fell in four months, from June 

 to September inclusive, and in two days of October, when
