 USUAL PURITY AND GERMINATING CAPACITY 



* These figures refer to "energy of germination," or the speed at which 

 high-class samples germinate. In order to complete a test of germinating 

 capacity, however, up to ten days should be allowed in the case of the first 

 thirteen species in the list, and up to fourteen days for the rest, except Poas, 

 for which a month should be allowed.
