CARE AND PRESERVATION OF STREET TREES 



Much has been written with reference to the cHseases of shade trees 

 and their control, but there seems to be Httle information bearing on 

 other phases of shade-tree work. This bulletin is intended to be the 

 first of two publications relating to this subject; and while its purpose 

 is to discuss the care and preservation of street trees, no attempt is 

 made to touch on the diseases of trees caused by insects and fungi. The 

 wa-iter's object is to point out, and to show by means of illustrations 

 and discussion, the harm to which our trees are subjected through 

 ignorance and neglect, and to awaken within the minds of public spirited 

 citizens a feeling that may prompt them to join forces in an efifort to 

 protect that to which nature has given them a life-lease, but not an undis- 

 puted ownership. 



The writer is indebted for valuable photographs and suggestions to 

 Mr. J. Horace McFarland, president of the American Civic /\ssociation 

 (Figs. 226. 227, 228, 235) ; The Newark Shade Tree Commission; The 

 East Orange Shade Tree Commission ; The Cleveland Park Commission 

 (Fig. 224) ; Boston Park Commission (Fig. 225), and Mr. John T. 

 Withers. Landscape Gardener and Forester (Figs. 253, 254, 255, 256) ; 

 and to others. 



I. Sources of Injury to Street Trees. (Pages 305-323) 



The sources of injury are many and serious, and the average citizen 

 realizes only too keenly that they are increasing. The many dangerous 

 enemies, against the ravages of which shade trees must be protected, 

 are of no trifling importance when considered in their relation to the 

 public welfare. On every side the observer may see numerous evidences 

 of these injuries, which become inexcusable when we learn that the great 

 majority of them can be traced to neglect or ignorance on the part of 

 owners or others, 



(7.) Public utilities. 



Trees are seriously damaged by escaping gas which penetrates the sur- 

 rounding soil, by electricity which is discharged from the wires that 

 come in contact with them, and by telegraph and telephone linemen 

 who may be encouraged to disregard the value of a tree in order to 

 run a line of wires with the least possible inconvenience. EiTectively
