Classification of these analyses is shown by the following summary:

*Samples germinated as a check on the quality of seed contained in 43 official samples which, 

 by law, require only the statement of purity. 



Field tests to determine trueness to type were conducted in cooperation with 

 the Departments of Vegetable Gardening and Floriculture, the former testing 

 150 samples of vegetable seed and the latter, 104 samples of flower seed. All 

 samples for these tests were collected and submitted by the State Commissioner 

 of Agriculture. 



The Seed Laboratory continued its practice of cleaning tobacco seed for 

 farmers and instituted the new service of cleaning onion seed. 



Dairy Law. (P. H. Smith, J. T. Howard, H. L. Allen.) During the year 

 ending December 1, 1936, 7,163 pieces of Babcock glassware were tested; 111 

 certificates of proficiency were awarded; and 222 creameries, milk depots, and 

 milk inspectors' laboratories were visited in order to check methods and pass 

 upon equipment in use. As a result of this inspection, three machines were 

 condemned. 



Advanced Registry Testing. (P. H. Smith.) Advanced registry testing 

 has been supervised by this department since its beginning in 1902. There are 

 now on yearly test 333 cows located on 40 different farms. This does not in- 

 clude the herd tests where all animals in each herd are placed on test. There 

 are 35 of these, 3 of which are supervised by men sent out from this office and 

 32 by cow-test association supervisors.
