If we examine the details of street tree control in various 

 American cities we find that there are in general use three 

 quite different forms of street tree administration. 



I. That in which the authority over street trees is placed 

 in the hands of an independent board or commission. 



II. That in which this authority is exercised by a Bureau 

 of the Park Department. 



III. That in which this authority is exercised by some 

 other bureau such as the Street Department or the Board of 

 Public Works. 



The second plan is without doubt the best, and the one in 

 most common use. In the case of New York City this form 

 of administration is provided for by charter, and the 

 authority over street tree maintenance and planting in each 

 borough is placed in the hands of the Borough Park 

 Department. 



In approaching the problem in Manhattan therefore it is 

 only necessary to perfect an arboricultural organization 

 already possible or existing in the Park Department, and to 

 determine the annual revenue which will be necessary for the 

 maintenance of such an organization. 



With the idea of arriving at an accurate estimate as to the 

 probable cost of adequate street tree control in Manhattan, 

 an investigation has been made of the cost of similar work 

 in a number of American cities where efficient departments 

 of city forestry are maintained. It is of course as difficult 

 as in the case of park operation, to standardize exactly such 

 a peculiar type of public service as street tree control. How- 

 ever, if the cost figures of various cities are interpreted with
