The use of a double row is never advisable since a hedgelike growth soon 

 results, which cuts off all light and air. 



The question of one or more species to the street has many adherents on 

 both sides, but the followers of indiscriminate planting have yet to produce 

 a street in California which is really ideal. By indiscriminate planting is 

 meant a mixture of species and not a combination of species in a definite plan 

 to produce a cartain landscape effect. The custom alternating two species is 

 very common but from those examples noted, it seams hardly as desirable as a 

 planting of one species. 



These are questions which must be determined on the ground and for which 

 there is no help but a fine sense of the fitness of things.
