Testing grass seed (Fraser). 



In testing the seed for germination power and purity it is more satis- 

 factory to weigh out a sample of the seed, separate the chaff and inert 

 matter, weigh it, and then proceed to make a germination test of the 

 remainder. For example, if a sample of awnless brome grass contain 

 10 per cent of dirt and chaff, and 75 per cent of the pure seeds are viable, 

 the actual germination power of the sample is 67.5 per cent, or 



75X90 



100 



= 67.5.
