used in only four of the ten counties of the state. Its distribution was 

 carefully supervised, and no vaccine was allowed to be used except 

 for: (1) a properly diagnosed outbreak; (2) where an outbreak had 

 occurred the previous year; (3) where a flock had been vaccinated the 

 previous year; or (4) where one flock, of two closely adjoining flocks 

 has been vaccinated due to an outbreak. {Miscellaneous Income) 



Bang's Disease Testing 



The total number of samples tested for Bang's Disease in 1935-1936 

 was 27,998, reports C. L. Martin. This included 23,823 Federal, 1,229 

 private and 2,946 out-of-state samples. This was an increase of 13,- 

 733 samples — due to the Federal work. The percentage of positive re- 

 actors was the same as last year — 8.36%. {Miscellaneous Income) 



Record of Performance and Poultry Approval 



Record of Performance work is officially supervised trapnesting and 

 breeding on poultry breeding farms. The supervisor, a representative 

 of the Experiment Station, makes eight annual visits to each farm giv- 

 ing it official recognition, and assisting the poultryman in his breeding 

 problems. Record of Performance certificates are issued for birds 

 producing 200 or more 24 ounce eggs, and Advanced certificates are 

 given for birds laying 240 or more standard sized eggs. 



The Record of Performance Association has ten members (two of 

 Barred Rocks, one of White Rocks and seven of New Hampshires.) 

 The Association has affiliated itself with the National Poultry Improve- 

 ment Plan, which should stimulate further interest in R.O.P. R. C. 

 Durgin is in charge. 



Poultry Approval, which was formerly called Poultry Certification, 

 has also become one of the steps in the National Poultry Improvement 

 Plan. This stage entails the handling of a flock of birds by the in- 

 spector who grades the birds into two classes, breeders and culls. The 

 superior individuals as to type, color, producing qualities and freedom 

 from inherited disqualifications, are held for breeders. 



There will be about 50,000 U. S. Approved birds on at least 35 New 

 Hampshire farms during the breeding season of 1937-38. {Miscel-

Inspection Service 



Feeding Stuffs Inspection. In the enforcement of the law regulating 

 the sale of concentrated commercial feeding stuffs, 384 brands were 

 analyzed for the State Department of Agriculture. The analyses re- 

 quired about 2900 individual determinations. 



Fertilizer Inspection. In the enforcement of the law regulating the 

 sale of commercial fertilizers, 106 brands were analyzed for the State 

 Department of Agriculture. These analyses required about 750 de- 

 terminations. 



Cooperation with the Smalley Foundation has been continued by the 

 analysis of some 30 samples. The results show that our laboratory is 

 maintaining its high standard of accuracy.
