On the Sevdfik Hills. 



[Oct. 



ed ; and some ■works have become as scarce as are the MSS. of Ahtsto- 

 PHANES, Some of these have found their way to England : and as a 

 case in point there is a work (the Parama yoga Vilasam, in Telugii) 

 of which I with much difficulty obtained one copy at Masulipatam : 

 two others (incomplete) have with his usual kindness been transmitted 

 to me by Professor Wilson : and another manuscript I discovered at 

 Oxford in the Bodleian library, whence I yet hope to obtain per- 

 mission to borrow it. I would willingly transmit a more legible copy 

 along with it in returning the original, which if left to its fate will perhaps 

 before long feast the worms.

 foimd in them. ^ By Piioby T. Cautjley, Esq., Capt. Bengal Artillery^

The mountains, a part of which I am about to describe, range (with 

 the exception of the debouchures of rivers) almost uninterruptedly from 

 the Sutlnj, which separate^ the territory of the British Government from 

 that of the Sikh chieftain, Runjeet 'Sing, to the Burhampootur river, and 

 the district uf Cooch Behar. Their general bearing, in the portion near 

 the Sutluj, is N. VV. and S E ; but in that approaching the Bur- 

 hampootur, it is many points nearer direct east and west. They lie at 

 the foot of the great tiimalayan < hain, with which they are in some 

 parts connected by a succession of low mountains ; but in others, as in 

 the districts under review, they are separated by valleys from three to 

 ten miles in width, and called by the natives Deyra Dhoon, Kearda 

 Dhoon, &c., or the Valley of Deyra, the Valley of Kearda, &c. The 

 highest peaks do not far exceed 3O0O feet, and the generality of the sum- 

 mits vary from 2000 to 2500 above the level of the sea. It is necessary, 

 however, to premise, that my observations have not extended further 

 eastward than the Ganges; and that whatever I may record, in this 

 paper, beyond that river, is given on the authority of others. 



Between the Ganges and Jumna rivers, this line of mountains is sepa- 

 rated from the great chain of the Himalayas by the Dhoon, or valley of 

 Deyra, the average width of which may be under ten miles. At the
