there is evidence that it constitutes 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 larger 

 lot from which it is taken. Because of the cost of labor 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 l)ox to prevent the loss 

 of fine particles and a change in the moisture content. In 

 order that the Department may have a satisfactory record of 

 the sample analyzed and may know whether or not the man- 

 ufacturer and the dealer are complying with the requirements 

 of the law, the following information should be submitted 

 concerning each sample.
