RESULTS OF WORK IN MISCELLANEOUS PROJECTS. 

 Inspection of Commercial Feedstuffs. 

 Two hundred and fifty samples of commercial feeding stuffs were analyzed 

 for the State Department of Agriculture by T. O. Smith and C. P. Spaeth 

 (Agricultural Chemistry) in connection with the enforcement of the state 

 law regarding the selling of feed stuffs. The results of this work are report- 

 ed in Bulletin No. 195 of the New Hampshire Agricultural Experiment 

 Station. A co-operative arrangement with the Federal Bureau of Chemis- 

 try whereby samples shipped into the state which were found adulterated 

 and misbranded are reported to the federal authorities, has secured action 

 in a number of cases. This materially strengthens the protection given 

 to the purchasers of feed stuffs in the state. 



Inspection of Commercial Fertilizers. 

 One hundred and four samples of commercial fertilizers were analyzed 

 for the State Department of Agriculture by Messrs. Smith and Spaeth. 

 The results of this work are reported in Bulletin No. 196 of this Station. 



Seed Tests. 

 Mr. Eastman tested 610 samples of grass and grain seed for farmers, coun- 

 ty agents, dealers and the State Department of Agriculture during the past 

 year. The results of these tests will be found in Station Bulletin No. 197.

Total 138 



For the year ending June 30, 1920, the number of seven-day tests was 

 49; of semi-official or yearly, 178. 



White Diarrhea Work. 



Tests were made of 17,000 hens during the past year by A. W. Richard- 

 son and P. I. Fitts (Poultry Husbandry) and resulted in the finding of ten 

 poultry farms, of 300 hens or over each, which were free from the disease of 

 white diarrhea. These farms hatched at least 100,000 chicks which were scat- 

 tered broadcast over the state, in many cases establishing new flocks which after 

 a year or so will be used to spread further the white diarrhea-free stock. 

 From the results of last year's work nine new such flocks have aheady been 

 estabhshed, making a total of nineteen now known to be free of the disease. 



What this may mean to the poultry interests of the state is shown by the 

 following instance of a Rockingham County poultryman. "Two years ago,"
