68 Earl of Minto's Barometrical Measurement 



broad river rolling with an impetuous course beyond the 

 mountains north of the whole Abor and Meeseemee countries, 

 and named the Sree Lohit ; but my Meeseemee informants and 

 the Laory Gohoyn, a Khamtee of extensive acquaintance with 

 their chiefs and knowledge of their traditions, have not pre- 

 tended that any such river exists. The Sree Lohit is only 

 Tcnown in Assam as a river crossed by the descendants of 

 Koonling and Koonlace in their progress to assume the sove- 

 reignty of Assam, near the Moongree Moongram Hills, which 

 are always placed in the direction of, or rather beyond Ma- 

 geron. It is probably the Irrawaddy. 



We cannot refuse credit to the assertion of both Khamtees 

 and Meeseemees, that the Irrawaddy rises in the neighbour- 

 hood of the heads of the Burrumpooter. 



I am not aware whether it is the opinion of the Pundits of 

 Hindoostan, that the Burrumpooter has its rise in the Lake 

 Munsorowar, but having had the Shastra Trita Koomoodee 

 examined, I find it therein stated, that the Dikurubakhinee, 

 or copper temple east of Suddeeya, is on its north bank. 



On the 29th March, I took with great care a section of the 

 Burrumpooter opposite the station of Suddeeya, which gave 

 the discharge 33,900 feet per second. On the following day 

 I took with equal care a section of the great river below the 

 junction, considering that accuracy would be more easily at- 

 tainable in a convenient spot here, than by attempting to 

 measure the several rapid streams of the Deebong. The result 

 was a discharge of 120,200 feet per second, deducting the 

 value of the Burrumpooter, and 12,000 feet assumed as the 

 outside discharge of the Deebong, we have 74,300 per se- 

 cond for the discharge of the large branch. The river had 

 risen at the time a few feet above the level of the cold season.
