148 THE GARDEN OF EARTH 



pollen are still kept separate in the cells ; while in another 

 diiection we are informed that all the care of the bees is 

 useless, since the different kinds of pollen are packed 

 indiscriminately together in the cells. 



A suggestion may perhaps be hazarded here that bees, 

 or rather communities of bees, may not all follow the same 

 plans. Some possibly may act in one way; some in 

 another. It would be interesting to know if any evidence 

 could be found of this. 



In an earlier chapter something was said about the 

 beauty of flowers, and the reasons why they may have

 real doubts ; which is, that they might bring gladness and

But another and a very important reason, if not for 

 their actual loveliness, yet certainly for their gay colour-

 no insects came to visit them, we should have a sad dearth 

 of pollen where it may be most urgently needed. 



Though we can hardly suppose that insects love
