THE UNKNOWN LAND 



I never heard it but the once. The usual note is 

 a sort of moaning howl, impossible to describe but 

 easy to recognize. 



Thus we penetrated gradually deeper and deeper 

 into this wild country; through low mountains, over 

 bush-clad plains, into thorn jungles, down wide 

 valleys, over hill-divided plateaus. Late in the 

 afternoon we would make camp. Sometimes we 

 had good water; more often not. In the evening 

 the throb of distant drums and snatches of inter- 

 mittent wailing song rose and fell with the little 

 night breezes.
