STATISTICS OF THE YEAR'S WORK. 



During the year (September 1, 1919, to September 1, 1920) 1,002 

 samples of feeding stiiflfs, collected of dealers and manufacturers, were 

 analyzed and are reported in this bulletin. Two hundred and four dealers 

 located 'in 113 towns were visited at least once. One thousand four hun- 

 dred and sixty brands of feeding stuffs were registered for sale in Massachu- 

 setts by 305 manufacturers. 



On account of the greatly increased cost of carrying out the provisions of 

 the feeding stuffs act with no increase in appropriation, local prosecutions 

 have not been attempted in cases where guarantees have not been substan- 

 tially met, the Experiment Station continuing to depend upon the co-opera- 

 tion of the Federal authorities for action against violators of the feeding 

 stuffs act when the feeds entered into interstate commerce. 



On the whole, the market, while not entirely free from low^-grade material, 

 has been quite free from misrepresentation and fraud.
