STUDIES OF MARKET MILK. 
BY W. A. STOCKING, JR. 

The milk annually consumed in this country in its natural 
form is estimated to have a wholesale value of something over 
two millions of dollars. The enormous amount of milk which 
is represented by this money value is used as human food, and 
a greater or less part finds its way into practically every house- 
hold in this country. It is easy to see, then, why there has 
been during the past few years such a general sentiment in 
favor of a better quality of milk for use in its natural form. 
This growing sentiment can be seen in the daily press, in the 
results of scientific investigations and in the individual demands 
of various households. 
This desire for a better quality of milk is only one of the av- 
enues through which the public is demanding better protection 
for its health. Pure food laws are no longer the exception and 
at present almost every article designed for human consump- - 
tion 1s more or less thoroughly controlled by law and comes 
more or less completely under legal inspection. All of this is 
in perfect harmony with the increasing sanitary and scientific 
knowledge which has developed during the past few years. 
The public agitation in regard to the quality of the milk de- 
livered to the consumer has not developed by itself but simply 
as one phase of the general demand for pure foods. Many 
milk consumers, especially in the cities, have come to realize 
that the ordinary milk which they are able to purchase in the 
_tmarket is not always what it should be from a sanitary stand- 
point and are demanding an article which they can safely use 
as food. Asa result of this condition there is at the present 
time a limited amount of milk put upon the market which is 
produced under conditions much more sanitary than those under 
which the ordinary milk is produced. This means an increase 
in the cost of production and this grade of milk is usually sold
