CORRESPONDENCE WITH MANUFACTURERS. 



In order that all manufacturers whose cattle foods were examined 

 have a chance to inspect the analyses before their publication 

 and offer such explanations as they thought best of discrepancies 

 between the guaranteed analysis and the analysis as found, also that 

 they might explain any adulteration if such existed, the following 

 circular letter was sent to every manufacturer whose goods were 

 examined: 



DEAR SIR: The miscellaneous laboratory of this Bureau, during the past two years, 

 has been making chemical and microscopical analyses of the various commercial feed- 

 ing stuffs sold on the American market, and will shortly publish the results of this 



work . The examination of has given the follow ing results :

MICROSCOPICAL EXAMINATION. 



We are sending to each manufacturer a copy of the analysis of his feeding stuff before 

 publishing the results, that he may, if he so desires, explain any differences existing 

 between the composition as determined by us and as claimed by him. If the analyses 

 do differ materially, any legitimate explanation which the manufacturer makes will 

 be carefully considered and published with the analysis of the feeding stuff. 



If the manufacturer makes no claims in regard to the composition of his goods, the 

 above remarks do not apply to him, and the data are sent only for his personal informa- 

 tion. You, of course, understand that these results are not to be used for advertising 

 purposes. A prompt reply will be appreciated. 

 Respectfully, 



(Signed) H. W. WILEY, 



Chief of Bureau.

I am duly in receipt of your tabulated results of the examination of Blatchford's 

 calf meal, Blatchford's poultry meats, and Blatchford's sugar and flaxseed. 



I am inclined to think that some of these samples were taken some time ago, and 

 do not represent the goods as now turned out, or as they have been turned out for the 

 last eighteen months. The cause of the change was the necessary introduction of a
