HOW PLANTS LIVE TOGETHER. 



L. H. BAILP^.Y. 



O tlie general ol^server, plants seem 



to be distributed in a proniiscnous 



and liapliazard Avay, without law or 



order. This is because he does not 



see and consider. 



The world is now full of plants. 

 Every plant puts forth its supreme effort 

 to multiply its kind. The result is an 

 intense struggle for an opportunity to 



live. 



Seeds are scattered in profusion, but 

 onlv the few can grow. The many do 



not find the proper 

 conditions. They 

 fall on stony ground. 

 In Fig. 94 this loss is 

 sh o w n . The trunk 

 of an elm tree stands 

 in the background. 

 The coverino; of tlie 

 ground, except about 

 the very base of the 

 tree, is a mat of elm 

 seedlings. There are 

 thousands of them in 

 the space shown in the picture, so many that they make a sod-like 

 covering wliicli sliows little detail in tlie photograph. IS'ot one of 

 these thousands will ever make a tree.
