satisfactory adjustment can seldom be effected on the basis of an 

 unofficial sample. 



Notwithstanding the objections which may be raised to the analysis 

 of samples taken without proper sampling equipment, the Station is 

 disposed to continue this work as long as there is evidence that it con- 

 stitutes a useful service. The samples so submitted should be drawn 

 from at least ten bags in a manner which will insure that the small lot 

 sent for analysis is as accurately representative as possible of the large 

 lot from which it is taken. Because of the cost of laboratory work and 

 materials, an analysis is not usually warranted on a sample drawn from 

 less than a one-ton lot of feed. 



A one-pound sample is sufficient for the analysis. It should be sent 

 in a glass jar or tin box to prevent loss of fine particles and a change 

 in the moisture content. In order that the department may have a 

 record of the sample analyzed, and may know whether or not the 

 manufacturer and the dealer are complying with the requirements 

 of the law, the following information should be submitted concerning 

 each sariiple.
