the fowls that are carriers of this disease can. 
be detected and eliminated from any breed- 
ing flock. The test is practical and accurate, 
and the man who intends to buy foundation 
stock with which to start in the chicken busi- 
ness should buy only stock which has been 
tested for several generations for white diar- 
rhea and which has been found free upon each 
test or which at least has-been found free for 
two consecutive generations. The buyer 
should lay particular stress upon this factor 
because there probably is no disease which 
carries off so many young chickens as white 
diarrhea. There is no known cure for it. 
Once established in a man’s flock the disease 
will do more to discourage him and cause 
him to go out of the business than any other 
single factor. 
Foundation stock should be free from 
such diseases as roup, canker, and tubercu- 
losis. While these diseases may not be 
transmitted from the parent stock to the 
chickens, yet there is at least a strong pos- 
sibility that such stock will transfer a lower 
vitality to the chicks and the chicks are then 
susceptible to the disease.
