72 THROUGH THE BRAZILIAN WILDERNESS

 the ponds near by; the peons, with a familiarity which to us 

 seems sacrilegious, but to them was entirely inoffensive and 

 matter of course, called them "the Jesus Christ birds," be- 

 cause they walked on the water. There was a wealth of

 country. The work of the collector is indispensable; but 

 it is only a small part of the work that ought to be done; 

 and after collecting has reached a certain point the work
