Fishes 



Not only do the arboreal and terrestrial animals enume- 

 rated above do good Avork by aiding to rid the country oí 

 this pest. Even the fishes and other aquatic animals which 

 inhabit the lagunas and streams assist in the good work. When 

 the wind blows the flying locusts into the water they are quick- 

 ly seized by the only too eager fishes. While making a jour- 

 ney up the Parauc'i during the month of September, Avhen the 

 voladoras were moving about, it very frequently happened 

 that many were thrown into the water by contrary winds. At 

 such times it w\as a real pleasure to see how rapidly they were 

 despatched by the numerous fishes which came to the sur- 

 face lor the food thus provided. At other times it frequent!}- 

 happens that the marching saltonas come to streams of water 

 and attempt to cross. Of course many of them also are des- 

 tro3'ed before they can reach the opposite shore.
