To keep swine plague within circumscribed limits^ the enforcement 

 of judicious quarantine regulations is specially indicated, and all 

 movements of pigs, when disease breaks out in a district, should 

 be stopped until infested places are discovered and clean places 

 recognised. All movements should be under the guidance of the 

 central authority, and when once pigs are moved from an inland 

 district into the metropolitan area, they should be killed at abattoirs 

 in that area, and not allowed transmission out of it. 



Early notification of the existence of disease should be promptly 

 sent by owners of pigs to the nearest authority, and the premises 

 upon which it prevails should be forthwith placed in quarantine. 



To keep the disease well within control no pigs should be allowed 

 to be removed from an infected farm until it has been sanitarily 

 improved. No movement of pigs from it, to keep within safe limits, 

 should be allowed for fully three months after appearance of last case. 

 It IS at all times dangerous to move pigs from insanitary styes when 

 the disease has made its ap])earance in them. Quarantine enforce- 

 ments should not be relaxed until the styes have been j)laced in 

 sanitary repair. In order to meet commercial requirements, fat pigs 

 could, under judicious inspection, be removed from a sanitary farm to 

 a slaughter house three months after last outbreak. It would, how- 

 ever, be safer to have the pigs killed and dressed on the farm and 

 forwarded to market as bacon or fresh pork. 



x\.ll pig styes should be registered and a registration fee collected 

 by the municipal authorities, the amount of the fee to be dependent 

 on the number of pigs kept. The fees collected could be devoted 

 towards defraying the expenses of inspection. 



SouKCKs AND Channels of Infection. 



1. Pigs derived from infected farms, or pigs that have come into 

 contact with them, or that have run over ground occupied by diseased 

 swine are dangerous sources of iTifection. It has been urged that no 

 pigs should be purchased from an infected farm. Under no circum- 

 stances should anyone run so grave a risk until it is placed in a 

 sanitary condition, and then twelve months should be allowed to expire 

 since last outbreak of disease before a purchase for stud purposes 

 from such a farm is made. In outbreaks chronic cases may 

 live three or four months without betraying distinctive signs of 

 disease, and it is only when they die that the true nature of the case 

 is ascertained. Evidence of cases such as these has come immediately 

 under notice. The disease may hang about a farm long after it is 

 thought that it has been exterminated. Farmers should raise their 

 own pigs and not trust to ])urchasiug animals from their neighbours. 

 If boars are required to improve the stock they should be purchased 

 from places above suspicion, and even then they should be kept under 

 observation for at least one month before being allowed amongst the 

 herd.
