although quite free is somewhat shallow, early after the rains. 
The next obstacle is the two whirlpools at Mooknoor which when 
the river is full, present a considerable obstacle, but not so when 
it is moderately full at which time the boatmen, who are very 
expert, manage to steer between them without danger. The pas- 
sage between Nulumpully and Mooknoor, is only tedious after the 
rains as during the freshes the rocks may be sailed over. The 
last obstacle in the Godavery is just at the junction of the Inda- 
rootee. The channel through the rocks, which are there high is 
very narrow, and pointed ones in it render the passage somewhat 
dangerous, " some of these" 'adds Captain Fenwick " I had removed 
the nature of the rock being soft slate."
