strangling the bird. The success of the treatment depends 

 upon getting the solution into the nostrils. This treatment 

 should be continued two or three times daily until a cure 

 is affected. Kerosene is also an effective remedy. The face 

 should be washed with a feather dipped in the oil and a 

 little oil injected up the nostrils. If the mouth or throat are 

 affected they should also be swabbed out with a feather 

 dipped in the oil. Peroxide of hydrogen is also used suc- 

 cessfully for injecting into the nostrils and swabbing out 

 the throat. If the swelling on the face has reached a stage 

 that pus has formed, an incision should be made, the pus 

 removed, and the sore washed out with the permanganate 

 solution or with the peroxide of hydrogen. When the dis- 

 ease has reached that stage, however, treatment will not 

 often be successful and it will not pay unless the fowl 

 has some special value. The sick fowls should be isolated 

 and the premises disinfected. Care should be exercised in 

 introducing new fowls, and it is a safe practice to put them 

 in quarantine several days before putting them with the 

 rest of the flock. 



Catarrh. Possibly in the large majority of cases, what 

 is thought to be roup is simply catarrh or colds. The 

 symptoms are practically the same. The treatment of 

 affected fowls recommended for roup may be followed for 

 catarrh. When colds or catarrh appear it is a sure indica- 

 tion that something is the matter with the housing. The 

 fowls may be crowded too closely together on the roost ; 

 there may be cracks in the walls through which the wind 

 blows strongly on the chickens, or there may be insufficient 

 ventilation. 



Diphtheria. This is not an uncommon disease among 

 fowls and it is very fatal. A false membrane grows in the 

 mouth and extends down into the throat. Treatment is not 

 often successful. Kaupp (Colorado, Bulletin 185) recom-
