recesses of the wood. It is the bill of the toucan at work, hammering away 

 at the bole of some lofty forest tree ; and away in the background all the while, 

 though the ear becomes so satiated with the din as not to notice it, is the 

 monotonous whistling or " churring " of a thousand cicadas, a concert which 

 seems only to emphasise the impression of solitude. 



But the forest after aU is not dead ; it is but a dormitory of sleeping creatures 

 well concealed and preparing for the morrow. Another day will come when 

 the air itself is fuU of life ; and so far as butterflies are concerned, one is bewildered 

 by their number. If not always caught or tracked to their haunts beyond 

 those festooned giants, it is, at least, a pure joy to make one's way down to the 

 tank, for its mesmeric attractions are all-embracing in the endless procession 

 of aerial flights which are ever and anon mirrored in its still, dark waters.
