FOOT ROT AND ITS PREVENTION. 49 



2 lb. of potash (pearl ash,) in I gallon of water over a slow fire for 

 half-an-hour. Keep stirring, and at any signs of boiling over 

 pour in a little cold water; then add 5 gallons of cold water. 

 Put this solution to the depth of i in. to i in. (just sufficient to 

 cover the hoofs of the sheep,) in a strong, well-made, water- 

 tight trough 12 ft. long by 18 in. wide, and about 6 in. deep, with 

 narrow strips of wood nailed across the bottom to prevent the 

 sheep from slipping. The trough must be set and fixed perfectly 

 level alongside a wall or other fence in some out-of-the-way place. 

 It should be provided with a good water-proof lid, secured by a 

 padlock, so as to prevent the possibility of danger from any 

 poison which might be left in the trough. There should also be 

 a wooden fence on the other side of the trough, extended some- 

 what at the entrance end, to guide the sheep into it, as indicated 

 in the diagram."

Before the sheep are driven through the trough, their feet should 

 be well pared; then walk them gently through and let them 

 remain in Pen No. 2 for half-an hour or so before taking them 

 back to their pasture. 



If sheep are badly attacked, we would recommend drawing out 

 all the affected ones and passing them through the trough a 

 second time, after remaining for half-an-hour in the pen. Should 

 this not cure them, repeat the process in a fortnight or three 

 weeks time. 



If a flock is very seriously affected it is really better to dress 

 each foot separately and hold the same in an iron pot in which 

 has been placed a certain quantity of the Arsenic and Potash
