ON TREES AND BIRDS. 



65 



roots, as they often do in cities, in laying sidewalks, as 

 you see has been done, in this picture. 



The next photograph will show you what takes 

 place. Of all the millions of little rootlets that are 

 at work on a tree there is not one too many; Nature 

 makes no mistake, root and top are evenly balanced. 

 Often there is a splendid tree encroaching on a side- 

 walk, and instead of swinging the walk to one side 

 and saving a valuable tree the officials of a town will 

 cut off its main roots to get a straight line. What's the 

 result?
