way. In that case the flock may be driven through a large pan 

 containing a solution which is about four inches deep and the 

 animals should be forced to remain in the pan for several 

 minutes to insure thorough treatment. This solution should be 

 made by dissolving copper sulphate in water in the proportion 

 of one pound to a gallon of water, or use chlorid of lime solu- 

 tion made by dissolving one pound of fresh chlorid of lime to 

 three gallons of water. 



Separate the diseased from the apparently healthy. Treat 

 the latter firs^t and move these to a clean place, e.g., new pas- 

 ture. If any of these become lame, examine, and if found 

 diseased, move them to the diseased flock. Repeat trough treat- 

 ment several times for the sound flock at about two-day inter- 

 vals. The diseased flock should have the same general treat- 

 ment, repeated and continued as long as necessary. Trough 

 treatment is satisfactory for both sound and average cases-, 

 severe cases must have individual hand treatment. 



Prevention and management. — Diseased animals should be 

 isolated from the healthy ones. Vigorous and repeated clean- 

 ing and disinfections of the infected premises are necessary to 

 the proper control and must begin early. Any good coal tar 

 dip in 5 per cent strength will do. Either very wet or very 

 dry pastures may be favorable to the development of the disease. 

 Hoofs should be kept pared to reasonable proportions. Cases 

 of foot-rot should not be neglected in the earlier stages, for they 

 are much easier treated then. They may be infectious, and 

 careful treatment and attention may prevent a general outbreak. 



Foul-Foot 



This is a disease of cattle resembling foot-rot of sheep and is 

 apparently infectious, and due in most cases to Bacillus necro- 

 phonis, which causes foot-rot. 



Treatment. — Trim off diseased horn freely. It is sometimes 

 advisable in the early inflammatory stages to poultice with bran 

 or oilmeal, using powdered charcoal (|uite freely in the poul- 

 tice. For mild cases, white lotion may be used once daily. 



For more serious cases, use ten per cent solution of any good 

 coal tar dip in glycerine once a day for two or three days, then 

 reduce to a 5 per cent solution and use every other day for a 

 week or two as necessary.
