EVERY one knows that the long cord or thong, called the 

 lasso, is the peculiar weapon of the South American 

 hunter. Almost from his earliest childhood the young 

 Gaucho learns to amuse himself with it, and as soon as he

 with a lasso ready grown in its own flesh. Yet it is so, for 

 in that class of animals, which ranks just above the sponges,
