JUNE 107 



as little red plaques floating in a colorless 

 liquid form the red blood of our bodies, so 

 little green wax grains of chlorophyll, scat- 

 tered through the transparent protoplasm 

 of the plant, give to it its green coloration. 

 When the sun is not too warm, these little 

 grains swarm out into the sunlight to catch 

 its every beam, and the result is, the plant 

 looks very green. As the sun grows warmer, 

 the chlorophyll grains will not come out so 

 fully on the surface of the leaves, but are 

 inclined to hide behind one another so as 

 to avoid the extreme heat. As a result, in 

 July the leaves at noonday are distinctly 

 lighter and less vivid in their green than 

 they are earlier and later in the day, or 

 than they are all day in June. 



STRAWBERRIES REDDEN 



But while the trees are struggling for 

 sunlight in the upper air, a host of humbler 

 plants, less ambitious than they, are creep- 

 ing about their roots and contenting them-
