TESTING GRASS SEED.

state and State commerce where packing material is used are 

 also important sources of weeds. 



It will be noticed from the appended tables that the per cent 

 of purity of seeds was for the most part high and that a large 

 number of samples contained no weed seeds or only those that 

 were not pernicious. 



It is impossible to get a correct idea of the average per cent of 

 purity of seed sold in the State from samples sent for examina- 

 tion, as one sample may represent only a few bags and another 

 a car-load. A statement of the per cent of purity of a seed gives 

 but little idea of its nature, as the impurities may be large and 

 consist of harmless seeds or indifferent weeds, while one show- 

 ing a low per cent of impurities may contain the vilest weed 

 seeds. 



The tables showing the results of the analyses of samples of 

 seeds follow.
