CHAPTER XLVII 



CANKER 



THIS disease may start with a small sore and then 

 work its way upward under the skin, producing a 

 swelling on the outside. If you lance the part 

 swollen you will find it, no doubt, filled with a 

 thick, cheesy substance. You might also start from 

 the point of the small sore and work up into it. It 

 is absolutely necessary that you reach the seat of 

 the trouble, and burn it out with a solution of five 

 grains of nitrate of silver to an ounce of distilled 

 water, but first of all remove all the yellow, cheesy 

 substance possible. Wash this cavity out daily and 

 use the nitrate of silver solution freely, and then 

 saturate a piece of cotton with a good antiseptic 

 and plug up the cavity. Mix up a light solution 

 of permanganate of potash and add this to the drink- 

 ing water, giving them no other water to drink. 



This is a very stubborn disease to cure, but with 

 persistency it may be very successfully combated. 

 Fowls once affected with this disease are liable to 

 produce this scrofulous disease in their offspring. 

 This disease is contagious and may be transmitted 

 to the balance of the flock through the drinking ves- 

 sels; therefore remove all diseased birds, and put 

 them into clean, disinfected coops.
