Damping the seed, later followed by a brief period over the 

 inlet pipe of the extraction chamber, shrinks the wings. !Fhe 

 separation is much more thorough than by the former method, 

 which breaks loose the wing, leaving the lower portion of 

 the base still firmly cohering to the seed. After the wings 

 are loosened, the seed is passed through a modified fnnning- 

 mill. A conveyor carries the material forward, dropping it 

 before a rapidly rotating fan. In this manner, the heaviest 

 particles - the seeds - are deposited near toe fan while the 

 lighter portions are carried into more remote chamber a. As 

 the fertility of seed varies directly with the weight, that 

 of greatest germination power is in the first pocket with 

 practicilly no debris. The foreign matter increases, and the 

 proportional amount of seed decreases, as does also the ger- 

 mination percentage, in each succeeding pocket. The first 

 pouch will test over seventy-five percent in a thirty-day 

 laboratory proof. 



Cleaned or uncleaned seed is stored after 



a simil'-.r manner, in hermetically sealed containers,- a capa- 

 city of forty pounds making a good unit. These are stored in 

 some location of uniform temperature approximating 4G. The 

 seed must be absolutely dry when sealed, and a certain air 

 space should be left in the can to permit of such respiration 

 as may be carried on through the epidermis.
