STREET TBEES.

CONSTRUCTION AND BUILDING. 



Shade trees have no proper part in any construction work, 

 whether of street, sidewalk or building. When they stand 

 near by provision must be made to secure them against in- 

 jury, otherwise they are sure to be damaged. Most of the 

 things to be looked after may be summarized as don'ts. 



Don't allow any guy wire or rope to be fas- 

 tened to a tree. But if this cannot be avoided 

 be sure that the tree is amply protected by wood blocks as 

 sh.wn in Fig. .11. A pretended guard of sacking as shown 

 in Fig. 10 is of no value. 



Don't*.

 must anchor a guy. 



Don't allow a tree to be used as part of a scaffold; it can 

 always be avoided. 



Don't allow bricks, stone or any building material to be 

 piled against a tree unless strong wooden guards are placed 

 about it. See Fig. 12. 



Don't allow piles of sand, stone, etc., to stand long about 

 the base of a tree ; such material will rob the roots of air 

 the same as a close pavement. See page 24. 



Don't allow a mortar bed where water saturated with lime 

 can How from it to the ground about a tree ; the roots cannot 

 stand it.
