STREET AND HIGHWAY PLANTING. 



and to the pedestrian on the sidewalk. In talking with a street super- 

 intendent of a certain town which has very good streets, most of which 

 are eighty feet in width, the opinion was expressed that thirty-five feet 

 was sufficient space for the road, and that the rest should go into 

 parking and pavement spaces. This w r ould produce a spacing as in 

 Fig. 39. Other arrangements might be made by varying the width of 

 the parking, the width of the pavement, or width of the strip between 

 pavement and property line, or by varying any two, or all three.

 The first is the case of the residential street which is very wide, at least- 

 one hundred feet. Then a wide parking space can well be spared from 

 the center of the roadway, and if judiciously planted will add much 

 to the beauty of the street. In most cases this central space is used for 

 shrubbery planting and for nothing else. Of course, in the case of 

 still wider streets with a central car line, a planting of trees might well 

 be used. This has been done in Washington, along Pennsylvania ave- 

 nue, the diagram of which see in Fig. 40. The other phase of the 

 central parking is the case of the narrow street flanked by tall buildings, 

 where there are no side parkings, and a tree has best chance for life in 

 the central space, where it can get a maximum of sun and air. Of
