the expenditure of large sums for the control of insect depre- 

 dations, New England has suffered a loss that should be 

 avoided in this State and intelligent planting will go far in 

 this direction. 



Quick Growing Trees are Usually of Short Life. 

 Quick growing trees such as the Carolina Poplar, Silver 

 Maple, and Boxelder have been planted too commonly. The 

 roots of the poplar are rampant in their growth and some- 

 times go a hundred feet or more to reach moisture. They 

 will enter sewer and water pipes and in a surprisingly short 

 time clog them with their fibrous roots. When planted near 

 sidewalks the roots of the poplar will oftentimes raise the 

 cement or stone. The Silver Maple and Boxelder are not 

 so vigorous in their root growth but they do have objection- 

 able qualities such as a growth of weak wood and a short 

 life. It has been found that as soon as quick-growing 

 species attain a desirable size, the trees have made their ulti- 

 mate growth and will soon decline, 



THE NECESSITY FOR PLANTING NEW STREET 



TREES. 



The value of good shade trees is beyond question. To 

 provide trees for shade and ornament for the future it is 

 necessary to plant now the best species along the streets of 

 the towns and the cities of the State. The constant removal 

 of street trees which have become weakened by increasingly 

 abnormal surroundings requires the replanting of these sec- 

 tions with new varieties that are better adapted to the 

 changed conditions. The lack of foresight in the past in 

 the location of trees along streets necessitates the planting 

 of new specimens spaced with due reference to the propor- 

 tion of other features in the street if any degree of excellence 

 in civic art is to be achieved. 



An introduction of a larger number of species of trees is 

 essential both to obtain a variety in the proper landscape 

 development of the municipality and to prevent the sudden
