602 Note on the Navigation of the river Nurbudda, QNo. 151. 



The following extract from his report gives the result of his obser- 

 vations as far down as Tulluckwara, with an account of the measures 

 he was compelled to adopt when stopped in his further progress at 

 the mouth of the Hatnee river : — 



" I left Mundleysir on the morning of the 21st March 1842, in 

 one of the ordinary passage boats used at the ferry, halted for the 

 night at Kuttora, and arrived at Chiculdah on the evening of the 

 22d at sunset. 



" This portion of the river, fifty-one miles in length, is navigable by 

 boats lightly laden until nearly the end of the dry weather, with the 

 exception of the rapids called Sahesur Durrah, which are about two 

 miles below the town of Muheysir. 



" This is rather a formidable obstruction, consisting of a belt of 

 rock stretching diagonally across the river, and intersected by a great 

 many narrow and tortuous channels, through which the water rushes 

 with great impetuosity, until it is finally precipitated over a shelf 

 about eight or ten feet in height into a sort of trough, at the extre- 

 mity of which it again becomes navigable. Luckily, however, there is 

 a back stream near the Southern bank, which affords a rather difficult 

 passage for unladen boats until within about a month of the rains, 

 but might easily be made practicable throughout the year by means 

 hereafter explained. 



" Between this and Chiculdah there are a few shallows and rapids, 

 but I observed no obstacle particularly worthy of notice, and have no 

 doubt that a comparatively trifling outlay would render this portion 

 of the river available for boats much larger than that I sailed in, 

 for nearly, if not quite, the whole of the year. 



" From Mundleysir to Chiculdah, the bed and banks of the river pre- 

 sent every where nearly the same features which may be exhibited 

 by the following section : — "
