Take. Arsenious acid 3 lbs. 



Carbonate of potash 2 lbs. 



Water 14 gals. 



Thte arsenic and potash must be boiled for at least half an hour in 

 the fourteen gallons of water in order that the arsenic may be 

 well dissolved. A sulRcient quantity of this solution is then 

 poured into the trough so that the liquid will be about three 

 inches deep, to permit it to thoroughly cover the feet and pas- 

 terns of the sheep. 



Affected sheep before being stood in the bath, should have 

 their feet pared; all fungoid growths should be removed. It is 

 not necessary to stand the sheep in the bath for any length of 

 time if the trough is over ten feet in length, the mere passing of 

 the sheep through it will be sufficient. After leaving the bath 

 care must be taken that the sheep are not allowed to graze until 

 the liquid has drained from their feet, otherwise the drippings on 

 the grass being eaten by themselves or other animals would 

 cause arsenical poisoning. 



It is a good plan to place the trough on some bare place as 

 far away from the farm buildings as possible, having a pen at 

 each extremity of the trough, so that the sheep can be driven 

 through without difficulty. The pen at the outlet to be used as 

 a draining pen, the sheep to be held there until the feet have 

 drained dry. The trough also should be provided with a water 

 tight lid and kept locked, otherwise it would be dangerous to the 

 live-stock of the farm. In mild cases of foot-rot, sulphate of 

 copper (blue stone) may be used in the place of the arsenic, this 

 should be used in the strength of one poimd to the gallon of 

 water. 



After the sheep have passed through the bath, it is found 

 very beneficial to apply quick lime to their feet. The easiest 

 method being to sprinkle the floor of a barn with the quicklime 

 and compel the sheep to walk on it. It must be borne in mind,
