botanic garden which is shaded from the son by brush overhead. Some 
seedlings were grown under this screen. The question is now forced 
upon me, “What shall I do with these plants to insure what would 
be called good results, so far as beauty of color and form are con¬ 
cerned ?” 
“Perhap the florist already has enough plants that bear yellow or 
orange flowers, such as sunflowers, zinnias, marigolds, and silphium.” 
The plants transplanted last year, with cultivation improved much 
in size, and size of flowers. To assist in securing variations, I shall 
give the plants a change of soil, moisture, exposure to sun, and shade. 
They will each have plenty of room, and good cultivation. A few of 
these may be crossed, but my chief reliance will consist in growing 
each apart from others and selecting to a type during several genera¬ 
tions, attempting to fix one peculiarity at a time. 
(Twenty-nine heads of flowers in variety were on exhibition as 
herbarium specimens.)
