CALIFORNIA PLANTS IN THEIR HOMES 



plants you have been studying. You will find some of 

 them working on more busily than ever after the rains 

 come. Others will take their vacation just when material 

 for food-making comes most easily; but you must remem- 

 ber that in plant life, as in business life, there is what is 

 called competition. The stronger crowd out the weaker, 

 and there is not room for all at the same time. So the 

 plants that know how to meet hard times wait until there 

 is less competition, and brave other dangers instead; and, 

 as we have seen, they make a success of life and are some- 

 times beautiful besides.
