are borne several nuts containing the seed of the 

 plant. 



In the case of the cactus the thorns were thrown 

 out to i^rotect the plant itself from destruction, but 

 in the case of the monkey-puzzle tree the animals 

 threatened not the tree itself but its offspring — its 

 nuts were so highly prized by the monkeys, and 

 their number was so few, that it was forced to take 

 protective measures to keep its seed out of the 

 reach of enemies. 



From this we begin to see that each plant has 

 its own family individuality, its own family 

 personality. Some plants, in order to insure 

 reproduction, produce hundreds or thousands of 

 seeds, relying on the fact that in an over-supply 

 a few will likely be saved and germinated; while 

 other plants producing only a few seeds protect 

 them with hard shells or bitter coverings, or, as in 

 the case of the monkey-puzzle tree, with sharp 



spines which make access impossible.

In the deep canyons of California's mountains 

 there grows a member of the lily family, the 

 trillium. 



At the bottom of these canyons there are places 

 where the sunshine strikes but one side. The 

 flowers on the shady side of the canyons are larger, 

 and the leaves of the plants are broader, and the
