SUMMARY. 



From the tables on the preceding pages, it will be noted that 

 171 of the 280 samples collected were guaranteed for purity and 

 156 for germination. In other words only 61 per cent, of the 

 seed represented by the samples was sold according to the law as 

 regards purity, and only 56 per cent, as regards germination. 

 These percentages are much lower than last year, when they 

 stood at 87 and 81 per cent., respectively. 



Of the total 171 samples which were guaranted for purity, 162 

 of them, or 95 per cent., were found to be up to or above the 

 guarantee. 



Of the 156 samples which were guaranteed for germination, 

 98 of them, or 63 per cent., were found up to or above the guar- 

 antee. This is a much poorer showing than last year. 



Among the seeds tested this year, alfalfa, alsike clover, corn, 

 peas, oats, red clover, timothy and wheat were on the average 

 above the standard per cent, of purity ; while barley, buckwheat, 

 millet, red top and white clover were below the standard per 

 cent. As regards germination, the average per cent, was up 

 to standard for all kinds of seed except corn, millet, peas, red 

 clover and white clover. The low germination of the corn and 

 peas was due to the very early freezing weather throughout the 

 country last fall. The low quality of millet and of some of the 

 clovers was undoubtedly due to the fact that they were old seeds 

 carried over.
