(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 should be exercised 

 to cut them smoothly, close to and even with the trunk and without 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 supervision 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 leaking from the mains, the owners of 

 the mains be required to pay to the city the cost of the removal of trees killed 

 and of planting new trees in their places. 



(6) That the land under trees in city parks be annually dressed with wood 

 ashes. 



(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. 



(8) That trees infested with leaf-feeding insects be sprayed regularly for a few 

 years, and thereafter as seems necessary. 



(9) That in winter insects and the cocoons of insects that injure the trees be 

 collected and destroyed. 



I advised the Good Citizenship League concerning the measures that should be 

 taken for the protection of the trees. As my recommendations, however, con- 

 tained practically the same advice as those quoted from the bulletin referred to, 

 it is unnecessary to repeat them here. 



Tree<> at Port Jefferson. 



On the twenty-first of November I visited Port Jefferson, Long Island, to deter- 

 mine, if possible, the cause of the unhealthy condition of Pine trees reported by 

 Mr. A. W. Law, of New York City. 



The trees I found to be Pitch Pine (Pinus rigidd). They are in a park on the 

 property of the Crystal Brook Park Association, of which Mr. Law is a member, 

 and are situated on a gravelly ridge; excellent soil, I should judge, for the growth 

 of this species. A number of trees were dead and others were fast dying. 



Two trees were dug up by the roots and examined thoroughly. One of these 

 was still alive though in a very weak condition, due, it appeared, to two causes. 

 The tree had been pruned probably two or three years ago and decay had entered
