meet present conditions, and this year a new law will be pre- 

 sented to the General Court for its consideration and adoption. 

 The proposed law differs from the present law in the following 

 particulars : — 



1. It is modeled as closely as local conditions will permit 

 after the uniform law proposed l)y the Association of Feed 

 C^ontrol Officials.

2. Great care should be taken in getting accurate samples. 

 The test from a sample carelessly drawn will not represent the 

 value of the milk or cream from which it is taken, no matter 

 how carefully the testing is done. 



3. Cream and curdled sam])les of milk should be weighed and
