 symptoms, as locked jaw, and wry neck, bring it 

 near to tetanus, or universal spasm.

 person, in the district where such diseases are said

Shelter is the first thing to be attended to in the 

 management of sheep. While every good shepherd 

 is decidedly hostile to their being confined, or to 

 their being forced into shelter, whether they wish 

 for it or not, it cannot be too strongly recommended 

 to all sheep farmers, to put the means of avoiding

 roving disposition, and exceedingly fond of liberty. 

 It is certainly a mistaken notion that fine woolled
