7. In all these registers, it will be observed that there is a sudden 

 rise of about four feet during the last ten days of April. As this 

 rise is succeeded by a sudden decrease, I would attribute the swell of 

 the river solely to the fall of these heavy bursts of rain which usual- 

 ly precede the steady falls of the Monsoon rain. The small amount 

 of rise that takes place before the setting in of the Monsoon is fur- 

 ther proved by the state of the Panlang Creek, which, with a mini- 

 mum depth of 2 feet of water, is never open for steamers dra win «" 

 four feet until the monsoon has fairly set in.
