 moisture. A careful study of local conditions extending over 

 a period of years is necessary in determining what species 

 to plant. It is safe to say that only a limited number of trees 

 is suitable for planting in 'any locality. 



A list of the trees which are generally considered best for 

 planting may prove helpful to the planter or one interested 

 in the selection of species for street and park work.

 variety of soils <and most easily transplanted. 



Norway Maple (Acer platan-aides Linn.).

 it is hardy, a rapid grower and is adapted to almost any soil 

 and situation. It grows a round, compact crown which is 

 often low and which forms a dense shade unless it is skillfully 

 pruned. It is well adapted to city conditions and is free from
