302 Seventeenth Annual Report of the 



or unloading; of all that have been fed any suspicious fodder or 

 other provender ; of all that have been exposed to be breathed 

 upon, licked or otherwise soiled by the infected animal or its 

 products, or supplied with water from trough, bucket, sluggish 

 stream or otherwise that have been exposed to contact and possible 

 contamination by the suspected animal or its products ; of all that 

 have had used upon them any halters, tie straps, covers, lariats, 

 barn or surgical instruments formerly used on the imported ani- 

 mals ; of all that have been in contact with the manure of such 

 animals that have been approached by any one who had been in 

 attendance on such animals or by any one who had previously 

 visited such animals, their domiciles, yards, roads, or products, or 

 with doo-s, cats or other domestic or wild animals that had been 

 admitted to the imported ones or their habitations or ranges, or 

 that have been in close proximity to such suspected places or things 

 to which it is reasonable to believe that vermin, rats, mice, skunks, 

 weasles, woodchucks, birds, and, above all, flies, are even remotely

 hair, wool, etc., may have been blown from the infected to the 

 previously uninfected places. 



There should follow the prompt closure of all roads, the strict-

 10 or 20 miles or more, according to conditions), and the thorough 

 disinfection of all establishments and objects involved. This 

 should apply equally to the ship by which the infected animals 

 were imported; and the district in which the plague has been 

 implanted should be retained in strict quarantine for a month 

 after disinfection. 



First adopted successfully, in Australia in connection with the 

 importation of infected cattle and the infection of two herds near 

 Melbourne, this has been carried out with equal success in Canada, 

 twice in 187."), when 305 animals were killed and the ships that 

 brought them held and, with the infected yards at Port Lewis 

 disinfected. Denmark and Saxony have established the same rule 

 with imported infected cattle. Bang says that even if only one 

 calf is found to be affected the whole herd should be killed and 

 the places disinfected and quarantined. England, too, now acts
