VALLEY OF THE BLACK EIVEE 37 



Where the village had been a populous one, or 

 inhabited for a long period, the ground was a 

 perfect bed of chipped stones, and among these 

 fragments were found arrow-heads, flint knives 

 and scrapers, mortars and pestles, large round

 apart for greater safety, were unfortunately lost

 a form of the guinea-pig; and of the tuco-tuco
