330 OUR SEARCH FOR A WILDERNESS. 



around beyond the first two valleys and then turning and 

 describing a second curve intersecting the first. Two of the 

 Jungle Wrens or Quadrille Birds '"'^ sang their incomparable 

 strains, each with a theme of its own. The first had two 

 phrases which it uttered alternately, thus; 



There is absolutely no other bird song with which to com- 

 pare it. The timbre, when heard at a distance, is that of the 

 Wood Thrush quality — sweet, litjuid and altogether ethereal. 

 But the distinctness of the notes and their remarkably intri-

After an hour or more of the most careful stalking in a 

 low swampy \'allcy, we heard the unmistakable thunderings 

 of Trumpeters '" or Warracabras, and my blood leaped in 

 response. Long before I could hear them, Francis had
