rets. Then they must be broken to let these animals alone, as they 

 are apt to make their appearance occasionally in passing from one 

 hole to another. It is only necessary to let the ferret and the ter- 

 rier be together in a yard or stable for a few times, cautioning the 

 latter not to touch the former, and the young dog soon learns 

 to distinguish his friends from his foes. Some terriers are not 

 hardy enough to brave the bites which they are liable to in rat- 

 ting, etc., and, indeed, the true terrier without any cross of the 

 bull-dog is a great coward, so that he is quite useless for the pur- 

 pose. In such a case, he must be encouraged by letting him kill 

 young rats at first, and as he gains confidence, he will perhaps also 

 increase in courage. If, however, the terrier is well bred, he will 

 rarely require anything more than practice.
