SHADE-TREES IN TOWNS AND CITIES 



Paris the height of buildings is Umited to sixty-six feet on 

 streets thirty-three feet wide. On streets less than twenty- 

 six feet wide, the height of buildings is limited to forty feet. 

 In order that street-trees might get enough light to develop 

 vigorously, it is found on the average that streets bounded 

 on both sides with buildings thirty-five feet high should 

 have a width of sixty-six feet, and streets having lines of 

 buildings sixty-five feet high should have a width of one 

 hundred and twenty feet, as shown in Figs. 6 and 7. 



On narrow streets having tall buildings, it is possible to 

 maintain trees in good condition by planting a single row in 

 the centre of the roadway, as shown in Fig. 8.
