 of disease found in various herds which have been examined by 

 the commission upon voluntary request. 



The following table shows a number of miscellaneous herds 

 in which a large percentage of disease has been found : — 



Voluntary Requests. 



In other words, the percentage of disease in herds thus far 

 examined varies all the way from up to 100 per cent. This 

 table also shows that the disease is not by any means restricted 

 to the more closely populated districts. Large percentages of 

 disease are naturally found in localities where, from the nature

 and the supply kept up in that way, the percentage of disease 

 is generally found to be small, excepting that, when disease
