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

 the Departments of Olericulture and Floriculture, which tested 468 samples of 

 vegetable seeds and 226 samples of flower seeds, respectively. 



The Seed Laboratory cleaned 74 lots of tobacco seed and 23 lots of onion seed 

 for Connecticut Valley farniers. The gross weight of the tobacco seed was 104.31 

 pounds and the net weight for the cleaned seed was 80.59 pounds. Onion seed 

 received had a gross weight of 1316.25 pounds which was cleaned to a net weight 

 of 346.95. 



Explanation of Tables 



Each of the following tables contains seeds, the sale of which is regulated by a 

 definite section of the Massachusetts Seed Law. The samples were taken by an 

 inspector from the State Department of Agriculture and worked at the Seed 

 Laboratory. Section 261A of the Acts and Resolves of 1937 and 1938, Chapters 

 288 and 363, defines the group from Alfalfa to Wheat, inclusive; Section 261 B, 

 Mixtures; Section 261C, Special Mixtures; and Section 261D, Vegetables. 



The last table is a summary, by wholesalers, of the total number of samples 

 tested under each of the above four sections and the number of samples found to 

 be mislabeled. 



Within each table the wholesalers are listed in alphabetical order and the 

 various kinds of seeds sold by them follow the same alphabetical arrangement. 



Mislabeling and other irregularities are emphasized in the tables by boldface 

 type and explained in the final column of the table or in footnotes. 



The number preceding each analysis is for identification and reference. The 

 line to the right of the letter "L" gives information copied from the label; that 

 to the right of "F" what was found in the laboratory analysis. 



All lots of seed included in this report were tested according to the Rules for 

 Seed Testing adopted by the Association of Official Seed Analysts.
