INTRODUCTION. 



This bulletin contains the results of the analyses of commer- 

 cial cattle and poultry feeds found in the Massachusetts market 

 during the late summer and fall of 1907. These feeds were col- 

 lected and the results are published in accordance with the Acts 

 and Resolves of Massachusetts for 1903, Chapter 122. 



During the year 841 samples of feed have been collected by 

 the official agent of the experiment station of which 715 were 

 selected for analyses. It not being possible to issue more than 

 one feed bulletin annually, the results of those feeds collected 

 early in the year were reported to manufacturers only, with such 

 comments and suggestions as the conditions warranted. 



In the present bulletin attention has been called to any un- 

 usual condition found to exist in the above mentioned feeds, 

 when it appeared that the facts would prove of general interest.
