STEEET AND HIGHWAY PLANTING. 



CHAPTER II. 



SELECTION OF TREES FOR STREET USE. 



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

 ceed upon a plan which shall produce an effect which is to approximate 

 the ideal street as closely as possible, we must have an ironclad 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 situa- 

 tion, as the same rule could not possibly apply for all sites. In regu- 

 lating 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 considered, for certain trees will produce good specimens 

 with a lack of attention which would prove disastrous 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.
