 sunlight, begin afresh to accumulate material for 

 next year's growth and next year's burning. 



But why do the flowers want so much to reach 

 the open air at all ? Why should they not blossom 

 contentedly under the enclosing ice-sheet? A glance 

 at No. 6 will serve to explain the reason. Flowers, 

 after all, are mere devices for the fertilisation of the 

 fruit ; it is the seeds and the next generation that the

 which, after all, has to earn its livelihood with 

 difficulty on a stern and rocky soil this beauty 

 that charms us is a mere matter of advertisement. 

 The plant wants its blossoms to attract the early 

 spring bees and honey-sucking flies, which carry 

 pollen from head to head, and so fertilise its seeds
