CHAPTER II. 



If, then, in accordance with the views just expressed, we are to proceed 

 upon a plan which shall produce an effect which is to approximate the ideal 

 street as closely as possible, we must have an iron clad standard by which every 

 species suggested for planting along the highways or streets must be tried 

 before selection. And here it might be noted, that there must be a different 

 interpretation of this standard for each situation as the same rule could not 

 possibly apply for all sites. In regulating this standard we must keep the effect 

 of the planting at maturity constantly in mind. What might seem eminently 

 satisfactory in young trees might prove impossible in the case of mature specimens. 

 This question of size and shape at maturity must then regulate the selection of 

 the species, the order of planting and the spacing in the parking, according to 

 the width of the street. Furthermore, the available amount of care must be con- 

 sidered, for certain trees will produce good specimens with a lack of attention 

 which would prove disasterous to others. If the planter will bear all these facts, 

 and many more, in mind, and have a sufficiently high ideal of the model street, 

 there is no reason why the ideal should not be approximated in all cases. 



The Ideal Street should be marked by many fundamental characteristics. Its 

 width should be proportionate to its use and location and never stinted; it 

 should be supplied with adequate drainege facilities, wide parkings and good 

 side walks. Wires of all kinds should be laid underground. One telephone 

 company in Riverside has already cooperated in this regard with good results. 

 In other towns, notably, Berkeley, Pasadena, San Jose, many of the poles ere 

 located in the backyards, giving a similar good result. The parkings should 

 be plf?nted uniformly throughout the entire length of the street unless soil 

 conditions prevent. Furthermore, the trees should be of uniform size and shape. 

 This is made possible only by a simultaneous planting of trees of the same ege 

 and a subsequent pruning throughout their growth which shall be necessary to 

 maintain such uniformity. This shape should elways be one which would allow 

 free circulation of light and air. This fector is assisted by judicious spacing
