examination. The finding of yellowish, white, cheesy nodules 

 or masses in the liver, spleen, intestines and mesenteries ia 

 strong evidence of tnbercnlosis. A bacteriological examination

 The sa ethods of treatment as recommended in tubercu- 



losis of oti lestic animals may be used in eliminating the 



disease from the premises and flock. This consists in killing 

 and cremating all birds showing visible symptoms, moving the 

 apparently healthy portion of the flock to new quarters and 

 wiping the eggs with alcohol. The old quarters should be 

 cleaned, disinfected, and then allowed to stand empty for several 

 months, when we should again spray with a disinfectant, and 

 scatter lime over the runs. If the cleaning and disinfecting have 

 been thorough, we may safely turn young or healthy birds into 

 the old quarters. All possible precautions against carrying the 

 infection to the healthy flock must be observed.
