tained, they search for and take the usual quantity of 

 food and thej' soon re.i^ain their former activitj'. 



The nature of the disease nia\' be readily determined 

 from the sym]:)toms above e:iumerated. If, however, 

 there is any doubt, the trachea of a bird which has 

 died from the disease should be slit 0])en and examined 

 for the sj'Ugamus. In case no birds have died, one of 

 the methods for extractinjf the worms from the trachea 

 of the living bird should ])e tried ( see treatment) . It 

 is important to the poultr>inan that the nature of the 

 disease should be detected as soon as ]:)Ossible after it 

 appears upon his premises in order that precautions 

 may be taken to stoj) the spread of the infection and to 

 eradicate it from the place. 



Treatment. — Separate the sick birds from the well 

 ones as soon as the disease is detected and clean uj) 

 the coops, ])ens and houses where they have been. 

 Disinfect all these ])laces and also the drinkingtroughs 

 or cups with a five per cent solution of crude carbolic 

 acid or with boiling water. Burn the bodies of the 

 birds which die. Keep the infected birds in a hou.se 

 which can be easil}- cleaned and disinfected, and see 

 that this house is kept disinfected with hot water or 

 five per cent carbolic acid solution. Megnin recom- 

 mends for disinfecting enclosures and contaminated 

 runs, s])rinkling with a solution of one p^xri of salicylic 

 or sul])huric acid in one hundred of water. Provide 

 ])ure water and uninfected food. 



By careful mani]nilation the worms may often be re- 

 moved from the trachea and the chicken radically cured 

 in that way. To accomplish this either a feather or a 

 long hair from the horse's tail may be u.sed. If a feather 

 is selected it is stripped of the we?) exce])t near the tij). 

 This may be used dry or it may be moistened with coal
