miliar with the new law and to have had opportunity to comply with its 

 requirements. 



Rules and regulations relative to the administration of the seed law 

 ^vere drawn up and adopted, and report and record forms were revised to 

 conform to the new law. Referee samples were handled in co-operation with 

 other seed laboratories as in past years. A small amount of work was done 

 ,as a member of the Public Service Committee of the Association of Official 

 Seed Analysts.

Potato Seed Certification 



Field inspection of the 147.12 acres of potatoes entered for certifica- 

 tion in the Colebrook area was carried out in co-operation with the State 

 Department of Agriculture. Tw'O inspections were given during the grow- 

 ing season, and all of the fields were certified. 



As provided in the certification rules, early in the winter of 1943-44 

 the growers submitted samples of tubers from their seed plots for a green- 

 house test. A seed piece from each of these tubers was grown at Durham 

 and disease readings taken. Twelves samples were tested. All w'ere with-

Pullorum Testing 



During the testing season of 1943-44, the staff of the Poultry Labora- 

 tory ran agglutination tests for the detection of pullorum disease on the 

 blood of 1,242,805 hens and related fowl owned by New Hampshire poul- 

 trymen. In addition, 64,541 birds were retested, making a total of 1,307,346 

 samples tested. 



The birds tested were from 748 flocks and of this number 26 flocks 

 were found to harbor the infection. The infected flocks had a total of 572 

 birds affected with pullorum disease. Thus 3.47 per cent of the 748 flocks 

 were found to be infected and .04 per cent of the total numl^er of birds 

 tested were found to carry the pullorum organism. 



The number of birds tested for pullorum disease has increased rapidly 

 since the inauguration of the program in 1918-19 when 4,000 birds were 

 tested. In 1925-26, after Pullorum testing had been under way for seven 

 years, there were 35,237 birds tested. Of this group 34 per cent of the 

 flocks were infected and 2.5 per cent of the total number of birds were 

 infected.
