which leave the main river ; while the flocks of wading birds 

 migrate northerly, thus greatly dispersing the food on which 

 the natives depend for their existence. The fishermen who 

 have been employed during the dry months in catching turtle 

 and fish on the sand-banks return to their villages, though

 when it now begins to subside. The rains, however, do not fall 

 continuously, though very heavy at times. Several days of 

 beautiful sunny weather generally intervene. The fine season 

 begins with a few days of brilliant weather the rays of the 

 sun breaking forth among the passing clouds. Towards the 

 middle of July the sand-banks again appear, flocks of gulls 

 and other water birds fly by, and the gaily-plumaged inhabit-

 it, throw themselves on the ground, and cling with claws 

 and beak to the sand to escape being carried helplessly away.
