MANUAL ON POULTRY. 41 



my former report how dangerous it is to place susceptible fowls in 

 coops that have been occupied with those sick with cholera when 

 no disinfection is practiced. During these experiments it has been 

 necessary to use the same coop over and over again, and frequently 

 it was impossible to place them upon fresh ground, and in some 

 cases even the accumulations of excrement were not removed ; at 

 all times reliance was placed upon this disinfectant, and the water- 

 ing troughs, coops and ground thoroughly saturated with it. In 

 no single instance out of more than a hundred have the ^most sus- 

 ceptible fowls contracted the disease from such disinfected grounds or 

 coops. The value of this agent is, then, fully confirmed by a large 

 number of cases. It deserves even more credit for efficiency than 

 I have before given it, since considerable accumulations of virulent 

 manure have been rendered perfectly harmless after a thorough satu- 

 ration with it. As a disinfectant, therefore, it cannot be too highly 

 recommended, and it should be largely used by all who suffer from 

 the ravages of this plague.'' 



In order, therefore, tsprevent this so-far incurable disease, all breed- 

 ers of poultry should use this simple, cheap and efficient disinfectant 

 at intervals of not more than a month. 



BUMBLE FOOT OR CLUB FOOT. 



This is generally caused by heavy fowls flying down from too high 

 roosts. It resembles what is known as "stone bruise" in the human 

 foot. On this subject Mr. Felch remarks : "The flesh of the foot 

 being so tough, the puss cannot escape ; therefore, if not attended 

 to it must congeal and an ungainly, troublesome foot be the result." 

 "When discovered before the puss congeals, lance the swelling at the 

 rear of the foot, and the pressure upon it in walking will press 

 the puss out and there will be a much smaller callous than if allowed 

 to settle down of its own accord. We have treated cases by making 

 an incision in front and rear of the foot, and those on the shank by 

 opening at top and bottom, and by the use of a syringe and a solu- 

 tion of carbolic acid, of one part of acid to ten parts of water, 

 cleanse them thoroughly when they all heal up." This is seldom 

 attended to in time to prevent evil consequences. 



THE RED SPIDER LOUSE MITE. 



Mr. Felch says : 



"This pest is the scourge of the poultry-house, and the source of
