THE LIFE OF THE ABARY SAVANNAS. 381 



ing whiter and more ghostly than ever, against the dark 

 clouds; flock after flock flapping silently over: a score of 

 Egrets 32 in an irregular line, then a dozen more smaller 

 troops; Wood Ibises 28 higher up and beating heavily, then 

 and our pulses quicken a half dozen great Jabirus 30 

 slowly throbbing toward the sunset. The Ducks prefer the 

 river, and above the fluid tide a living river of birds sets up- 

 stream, hosts passing until long after dark. We paddle in 

 the early dusk to mid-stream and the whistling stream of 

 Ducks curves gracefully upward, descending again when.

 share to the confusion, but the major part of the medley is 

 due to crocodiles, who wait until night before beginning 

 their active, noisy business of life, which, be it concerned 

 with food, mate or play, requires a vast deal of splashing 

 and bellowing. This latter is a deep abrupt roaring like 

 the final roars of a lion's cadence. An eight-foot croco-
