POULTRY DISEASES AND THEIR TREATMENT. 65 



doubt is the surest way to get rid of the disease and wherever 

 possible it should be done. However, where the disease is 

 found in large flocks of birds such measures would bankrupt 

 the owner. Or a man may have a very fine strain of birds 

 which he has spent many years in perfecting and which it 

 would be impossible to replace. In such cases Morse proposes 

 "Banging" out the tuberculosis according to the methods of 

 new-herd-building in dairy cattle as proposed by Prof. Bang of 

 Copenhagen. Morse's directions for "Banging" out tubercu- 

 losis are as follows : "Secui^e new or thoroughly disinfected 

 ground, keeping it absolutely free from contact with the ground 

 used by the infected flock. Erect new houses on this ground. 

 Collect the eggs from the infected birds and wash them in 95 

 per cent alcohol or in a 4 per cent solution of some good coal 

 tar disinfectant. Incubate these disinfected eggs in new incu- 

 bators. When hatched, remove chicks to new brooder houses 

 on the new ground. These growing chicks should be cared for 

 by new men, that is to say, either different men from those that 

 care for the old flock or if you are compelled to use the same 

 men they should disinfect their hands and shoes and put on 

 fresh overalls before handling the new stock. Have different 

 feed bins and different pails for distributing it. As soon as you 

 have built up a clean flock destroy the old and disinfect the 

 ground occupied by them by the method outlined above." 



This method is, no doubt, excellent in theory and if carried 

 out with complete and never-failing attention to details might 

 work. It is doubtful, however, whether in actual practice a 

 poultryman would ever be able to carry it through successfully 

 or profitably.
