It is seen that the seeds formed in the capsules of covered flow- 

 ers is practically the same as in those for uncovered flowers. It 

 is further noted that the D. Stramonium and D. Tatula have the 

 same seeding capacity, and that this is nearly double that of the 

 D. Meteloides. 



Morning-Glory Exclusion Experiment. 



Seventy-five capsules resulted from the one hundred exclusion 

 tests among the various kinds of morning glories ; some of these 

 were immature and a few were used for greenhouse planting, 

 so that only thirty-four were counted, and these produced 152 

 seeds, or an average of 4.47 seeds for each capsule. An equal 

 number of capsules grown in the open gave 167 seeds, or 4.91 

 per capsule, a result that indicates that the morning glories are 

 very thoroughly close-fertilizable. 



EXPERIMENTS WITH ORNAMENTAL PLANTS. 



Antirrhinum (Snap-Dragon). A blend secured between the 

 "Dwarf White" and the "Giant Crimson" was grown this season, 

 together with the parents. In height they approached the "Giant 

 Crimson," bearing many flower spikes of a lighter red than the
