116 LITTLE TRUDY'S BLUE FLOWERS 



center of the flower, we botanists call it the stigma, 

 and not until the golden dust from his bade sticks 

 to it, and is taken off can we say his express pack< 

 age is delivered. 



"If it were not for Master Bee's carrying this 

 yellow powder and letting it touch these particular 

 spots In other flowers, few seeds would be formed 

 and we should not have nearly so many flowers. 

 And the Blue Flags know very well how to tempt 

 him to visit them. They give him a sweet, lus- 

 cious feast and it is only polite of him to do some- 

 thing in return for them. Dame Nature besides 

 has given him wings so that he can travel about 

 from flower to flower without even buying a rail- 

 road ticket. The flowers, of course, must spend 

 their whole lives in the very same spot. We 

 and the bees can go to see them ; they cannot come 

 to us." 



Then Tommy told Professor Bonn how his 

 little sister had gone to visit the Larger Blue 

 Flags and how frightened we all had been when 

 thinking she might be lost. 



" Little Trudy knew they were blooming in the 

 swamp," Tommy said, " because the milkman 

 brought her a bud one morning, and it had come 

 out in water. No one thought she could walk 

 so far." 



Tommy also said that he had scolded her him- 

 self, and that she had promised him never to run 

 away again.
