allowed between the results of the test and the guarantee, 

 as follows: 



Guarantee Allowable variation 



% r % 



90 or over 6 



80 or over but less than 90 7 



70 or over but less than 80 8 



60 or over but less than 70 9

Accordingly, a sample guaranteed 92% germination is 

 "satisfactory" if it tests 86 'a to 98 '^i-. A sample guaranteed 

 Sb''/c may fall as low as 78% or as high as 92%. If a 

 sample tests higher than the per cent of variation allowed 

 it. is marked "Above" in this bulletin or, if it tests below 

 the variation allowed, the actual figure is reported. 



The summary table on the last page will show the general 

 results of the seed inspection work for the year ending 

 June 30, 1930. A large proportion of the samples were 

 found to be satisfactory but in purity more samples of 

 Hungarian and Japanese millet were found to be "below" 

 their guarantees than last year, and in germination the 

 same was true of Japanese millet and Timoth}-. Last year 

 88 %• of all samples were found satisfactory or better in 

 purity and 83%) were found satisfactory or better in ger- 

 mination. This year the corresponding figures are 86%' 

 and 80%'. While these figures perhaps are not alarming, 

 they show a trend in the wrong direction.

 Agronomy, who ably assisted the writer with the analytical 

 work in the laboratory, are herewith acknowledged.
