MEDICAL MILK COMMISSIONS AND CERTIFIED MILK. 5 
METHODS AND WORK OF THE VARIOUS MILK COMMISSIONS. 
NUMBER OF COMMISSIONS AND WHEN ORGANIZED. 
As previously stated, the first milk commission was organized 
April 13, 1893. An effort has been made to get correct data as to 
when subsequent commissions were organized, but this has proved 
an exceedingly difficult thing to do. Several commissions have given 
two different dates of organization, which is rather confusing in 
compiling statistics. This is probably due to the fact that many 
commissions were in existence and then for some reason or other 
became inactive for one or more years and were afterwards reor- 
ganized and carried on the original work. Fifty-four commissions 
reported the dates of their organization, and from their answers the 
following table has been arranged :

The most rapid increase is seen to have taken place from 1906 to 
1908, and since that time the increase has somewhat fallen off. This 
falling off in the number of commissions organized is probably 
explained by the fact that the field is being better covered so that 
new commissions are less needed than formerly. 
Not only has this movement spread in this country, but two or 
three commissions have been formed in Canada which conform to the 
same standards as those in the United States. 
In order to obtain information as to the medical milk commissions 
a large number of circulars were sent out to the various commissions 
in the spring of 1912. Replies were received from about 65 commis- 
sions, and it was found that quite a large number of these had become 
inactive either through lack of demand for certified milk or because 
of inability to find dairymen who would submit to the regulations of 
the commission. 
NUMBER OF CERTIFIED DAIRIES AND QUANTITY OF MDLK PRODUCED. 
The number of dairies producing milk for any one commission 
varies from 1 to 20. Several commissions were found to be still in
