RESULTS OF SEED TESTS, 1927. 3 



respect to which the seed must be guaranteed at place of 

 sale. 



The work of the seed testing laboratory in respect to 

 these seeds is to subject them to tests in order to see if they 

 prove as good as their guarantees indicate. In reporting 

 the findings this year the usual variations between our 

 results and the guarantees have been allowed. These varia- 

 tions are fully explained in the bulletin for last year and 

 will not be repeated here. Practically all tests on seed 

 were completed and reports on special blanks mailed to 

 their respective dealers by the first of July. A very few 

 were finished and reported in July. 



A summary table is appended at the end showing that 

 a large proportion of the seeds collected this year is entirely 

 satisfactory. Only 7.5 per cent of the samples were less 

 than satisfactory in purity, but 14.8 per cent failed to sat- 

 isfy our requirements in germination. Some of these un- 

 satisfactory results were obtained on seed from dealers 

 who seldom violate the requirements. Probably none were 

 intentional. Results strongly emphasize the importance of 

 eternal vigilance in handling seed.
