Each division in the proceeding pages shows the number of 

 seeds planted each time, the length of radicle and plumeule, 

 the number of days they were dried, the number of days they re- 

 mained in the germinator; in the germination, the number and 

 length of stem and root. 



Conclusion:- Com may be thoroughly dried after the radicle 

 has developed to so great a degree as to pro.iect one millimeter 

 beyond the seed coat and still grow if the proper conditions 

 are reestablished, 75# to 100£ if the dry period does not ex- 

 tend longer than twelve days and 50% to Ibt will revive if the 

 dry period is from twelve to thirty days in length. Evidently 

 the time could be much extended and at least 5 0% would revive 

 under proper conditions but my experiments were continued for 

 thirty days only. 



When the radicle has once grown to a length of five milli- 

 meters the time of drying must not extend over more than eleven 

 days or none will revive, and only b0% will grow after only 

 drying three days. If the radicle has once attained a length 

 of eleven millimeters 2b% will revive during the first eleven 

 days of drying but will not revive after that time, With the 

 radicle having grown to a length of twenty millimeters, no 

 grains will start again after drying more than three days. 

 However, it is possible for 50# of those dried not more than 

 three days to revive. Should the radicle be longer than twenty
