ordinary routine, combined with the individual inspection 

 of feet. 



Dipping and its principles have been dealt with at 

 p. 422, but it may not be amiss here to draw attention to 

 the question as a routine of flock management, both of 

 preventing fly attacks and acari. 



The dipping time varies, depending upon the part of the 

 country, while many flock masters never dip. Dipping in 

 the autumn is perhaps the more common practice, though 

 in Scotland it is not done until as late as October or 

 November. In some parts two dippings a year are 

 practised, viz., after shearing, and again in the autumn, 

 and this practice is rational and recommended. Lambs 

 may also be dipped twice a year, which is the custom in 

 some localities, but neglected in others. 



The care to be taken in dipping, and the agents 

 employed, are fully dealt with at p. 422. 



PIGS.* 



The pig gives less trouble to manage than any other 

 animal of the farm, and yields an excellent return, for there 

 is no animal that puts on so much weight for a given 

 weight of food, and none where early maturity can be so 

 readily practised. 



The only period, in fact, in the life of the pig where any 

 anxiety arises is just after weaning ; but there are few of 

 the dangers of parturition as in the sheep, seldom any 

 after-effects as in the cow, while the digestive system can 

 accommodate itself to the most varied diet, and continue 

 to turn it to useful advantage. The weak point about the 

 pig appears to be his susceptibility to cold, which is much 

 more marked than in the case of cattle and sheep.
