 were abundant in the North American Miocene.

 science, Francisco Moreno, had some years pre 

 viously made a discovery which showed that 

 not many thousand years back, when the In 

 dians had already come into the land, the huge 

 and varied fauna of the Pleistocene still lingered 

 at the foot of the Andes. He had found a cave

 times when its human tenants were absent. Be

 beds, and enclosures walled with stones for pur

 which their dogs were kept. Whether these 

 early Patagonian Indians had dogs I do not
