88 The Lung Plague of Cattle. 



"8-. Give two drachms Powdered Copperas (Green Vit- 

 riol) daily to each cow ii> meal or grains ; or, divide 1 lb. 

 Copperas into 50 powders, and give one daily to each 

 adult animal. 



"9. Do not nse for the surviving cattle any feed, foddei 

 nor litter that has been in the same stable with the sick. 

 Tliey may safely be used for horses and sheep." 



In certain cases further measures are needed, as re- 

 moval of the flooring and soil beneatli, or even the cre- 

 mation of the entire structure. Drains must also be 

 cleansed. 



(m) Quarantine the Premises for Three IlontJis after the 

 last sick Animal has been Killed or has Recovered. 



Free and continuous exposure to air is one of the best 

 disinfectants, and after the disinfection the exposure of 

 the empty premises with the doors and windows open 

 for three months will usually complete the purification. 



(n) Hay, Fodder pcnd Feed in Infected Buildings to he De- 

 stroyed or Fed to Horses, Sheep or Pigs. 



It is needless to insist upon this as such fodder has 

 been subjected to the fever-laden breath of the sick and 

 should only be used for animals that are insusceptible to 

 the contagion. 



(o) Manure from Infected Herds to he tJiorougJiIy Disin- 

 fected ivith Chloride of Lime, or Hauled out hy Horses to 

 Fields adjoining no Cattle Pastures, and. then Ploughed under. 



Though we cannot say that the defecations as passed 

 are infecting, yet, as they lie in and around infected sta- 

 bles, they are liable to take up and convey the infection, 

 and we have repeatedly traced outbreaks to this source. 



Like fodder, however, it is harmless to horses, and 

 provided these do not stand as mates with cattle they 

 may be safely used in disposing of it. In the vicinity of 

 cities it can be safely applied on market gardens.

 for Three Months after their Removal.
