Another feed is guaranteed to contain 6 per cent, to 8 per 

 cent, fat and by analysis is found to contain only 5.80 per 

 cent. Thirty per cent, of this year's feeds which carried a 

 sliding scale guarantee did not meet even the minimum 

 figure. This fact should be sufficient warning to the con- 

 sumer not to buy the feeds of those manufacturers who 

 violate this provision of the law. In publishing the guar- 

 anteed analysis of such feeding stuffs in this bulletin the 

 maximum figures only have been used. 



REQUESTS FOR ANALYSIS OF FEEDS 



The Department is frequently asked to make analysis 

 of samples of feeds for individuals. This it is always glad 

 to do when the circumstances warrant. It must be pointed 

 out, however, that the privilege is sometimes abused- Many 

 of these samples apparently represent only a handful of 

 feed taken from a single bag and are sent to the Depart- 

 ment carelessly wrapped in paper or in a pasteboard box 

 from which much of the fine material may have been lost. 

 The analysis of these samples requires the same expendi- 

 ture of labor and materials as the analysis of an ofl[icial 

 sample ; yet the figures obtained may be worse than worth- 

 less if the sample examined does not accurately represent 

 the lot from which it was taken. 



On account of the expense involved in making these 

 analyses and also the possibility under present conditions 

 of the figures obtained being unreliable, the Department 

 wishes to suggest : first, that in cases where the amount of 

 feed is less than one ton, instead of sending a sample for 

 analysis, the consumer writes us asking our findings on the 

 last official sample of this feed which we have analyzed : 

 and second, that where the amount of feed is more than one 

 ton, a sample be taken from at least ten bags in a manner 

 that will insure its being accurately representative of the 

 whole lot sampled. In order that the analysis may be of 

 value to the Department as well as to the individual and
