Trees and How to Know Them 



[357 



WHY WILLOWS ARE FOUND AT WATERSIDES 



We are so accustomed to seeing willows at the edges of streams, that these trees 

 have come to seem most "at home" there. As a matter of fact, the planting of 

 willows near stream banks has practical value; their roots, powerful and extensive, 

 have a restraining effect on the soil and help hold it in place in case of a flood. 



Willows and Their Roots: Willows are most likely to be found 

 near water, and they are valuable in controlling watercourses in 

 floodtime because of their extensive roots. By placing willow twigs 

 in water you can demonstrate how easily they form rootlets. A 

 twig lying on moist soil will develop them in the same way along 

 its entire underside as shoots appear from the buds on the upper 

 side.
