AGRICULTURAL RESEARCH IN NEW HAMPSHIRE 63 



State inspectors and will be reported in Bulletin 349; the remaining 142 

 samples were sent in by private individuals. Furthermore, the usual 

 referee work was continued. 



Competent staff members have succeeded in getting the last session of 

 the legislature to pass a new seed law. The following three new features 

 are included in this law: all vegetables and agricultural seed are now re- 

 quired to be tested within nine months of being offered for sale; a noxious 

 weed law is included forbidding certain weed seeds from being shipped 

 into the state; and a vegetable seed law is included.

Potato Seed Certification 



This service to the potato seed growers of the state was established 

 and carried on for many years by Dr. O. R. Butler, botanist of the Ex- 

 periment Station. After his death, in 1940, the work was done coopera- 

 tively with the State Department of Agriculture. Most of the field in- 

 spection work was gradually shifted until the season of 1942 when it was 

 entirely absorbed by the state department. 



In 1943 the Experiment Station was again asked to help out in the 

 emergency, and Stuart Dunn, the station plant physiologist, was assigned 

 to take charge in June, 1943. He had previous experience in the work 

 under Dr. Butler and had charge of it during the latter's last illness. The 

 total acreage during the current season is 147.12, all in the Colebrook area 

 in the northern part of the state. 



Beginning in 1941 a greenhouse test was required of all potato seed 

 submitted for certification. This is carried out with the aid of the station 

 pathologist, i\l. C. Richards. Each grower is required to submit to the 

 station at Durham a sample of tubers from each field to be certified. 

 Plants are grown from these in the greenhouse, during late winter, and 

 the disease readings are used to supplement the field inspection reports. 

 This is in lieu of a Florida test required by certifying agencies in some 

 other states.

Dairy Bacteriology Testing 



For the year ending June 30. 1943, 1698 samples of milk have been 

 tested for bacteria. The individual farmer samples were first pasteurized 

 and then the standard plant count was made on the pasteurized samples. 

 Of the total samples tested, 1066, or 62.8 per cent, had a count below 

 10,000, and only 95, or 5.6 per cent, had a count of 100,000 or more. 



Other services conveyed under dairy bacteriology testing include 

 the Babcock testing of milk samples, the calibration of Babcock glassware, 

 and the supplying of the Babcock glassware to the D. H. I. A. testers. 

 ,Nearly 100 samples of milk were tested for fat for people who brought, 

 or sent, their samples to the station at Durham. During the year 908 milk 

 test bottles and 84 pipettes were caUbrated.
