CITY FORESTRY AND SHADE TREES 163 



red, pine, white and scarlet oaks white ash and tulip 

 poplar are also desirable and the choice depends upon 

 the location, soil and particular planting problem to be 

 solved. For a street of average width the city forester 

 would use one type of tree with a given spacing while 

 on the narrower street another kind would be needed

 finally a mulch must be placed around the base of the 

 tree and a metal guard put in place to protect against 

 gnawing horses and passing vehicles. 



The moving of large trees may require his attention 

 from time to time, for while as a rule the smaller the
