vigorous growing tree. From this they 

 speed to other bushes and trees which 

 they kill. 



To sum up the points against the 

 tree: I . Rapid grow^th and soft w^ood 

 make necessary frequent trimmings. 



2. Surface roots w^ill lift any pave- 

 ments and destroy all beautiful turf. 



3. Drainage pipes are often filled v/ith 

 roots. 4. It is a short lived tree. 

 5. The dropping of flow^ers in the 

 Spring and leaves throughout the 

 season need much attention to render 



grounds attractive. 6. The worst city 

 insects live on the tree and propagate 

 in great numbers and the height of the 

 tree makes it impossible to spray proper 

 poisons effectively. 



While this is probably the best of the 

 poplars, w^hat 1 have given w^ould show^ 

 it a short lived, and in the long run, our 

 most expensive tree. With so many 

 good trees to plant along our streets, w^e 

 ought to check such an extensive plant- 

 ing of this tree.
