 is not merciful, frequently saves himself all trouble 

 and delay by knocking it senseless with a blow of 

 his whip-handle, and without checking his horse. 

 I have seen a lamb, about two days old, start up 

 from sleep, and immediately start off in pursuit of 

 a puffball about as big as a man's head, carried

I have often been struck with the superiority of 

 the pampa or creolla — the old native breed of sheep 

 — in the greater vigour of the young when born over 

 the improved European varieties. The pampa 

 descends to us from the first sheep introduced into 

 La Plata about three centuries ago, and is a tall, 

 gaunt bony animal, with lean dry flesh, like venison, 

 and long straight wool, like goats' hair. In their 

 struggle for ex;istence in a country subject to sudden 

 great changes of temperature, to drought, and fail-

 qualities which make the sheep valuable to man as 

 a food and wool-producing animal; but on the 

 other hand they have to some extent recovered the 

 vigour of a wild animal, being hardy enough to 

 exist without any shelter, and requiring from their
