both develop large spreading crowns and grow with great 

 rapidity. The American sycamore is, as a rule, more subject 

 to disease than the Oriental variety, and in consequence the 

 latter is usually given the preference. 



There are a number of American lindens (basswood) planted 

 in the streets and parks of New Haven. This species grows 

 rapidly and develops a large, round crown which casts a deep 

 shade. With proper care the American linden makes an excel- 

 lent avenue tree, but it is liable to be injured by storms and, if 

 it is neglected, disease is apt to attack the wounds; eventually 

 killing the tree. 



The European varieties of linden are to be recommended on 

 account of the perfect symmetry of their compact crowns. 

 They thrive admirably in this climate. 



Ash is often planted as a street tree, but its tendency to fork 

 and to become straggling makes it less desirable than those 

 already mentioned. 



To summarize what has been discussed above, we make the 

 following 



RECOMMENDATIONS. 



1. The rigid enforcement of those city ordinances which forbid the 

 bruising, injuring, or destruction of trees, and the fastening of animals 

 to trees in such a way as to injure them, 



2. That all trees standing within reach of horses in the street be 

 protected by frames or wire netting, so that they cannot be mutilated. 



3. That when limbs are removed from trees, greater care be exer- 

 cised to cut them smoothly, close to, and even with, the trunk and with- 

 out tearing the trunk bark. The exposed wood should be painted with 

 coal tar. 



4. That the stringing of electric wires be done only under the super- 

 vision of the Board of Public Works, and that this supervision be paid 

 for by the company doing the work. 



5. That when trees are killed by gas leakage from the mains, the 

 owners of the mains be required to pay to the city the cost of the 

 removal of the trees killed and of planting new trees in their places. 



6. That the land under trees in the city parks be annually dressed 

 with lime and with odorless fertilizer of the composition named, at a 

 cost of from $11.00 to $12.00 per acre. 



7. That on new streets, when the building line is far enough from 

 the street line, it is desirable to plant just in front of the property line, 

 rather than just back of the curb.
