DEPARTMENT OF MUNICIPAL ARBORICULTURE 245

 wood. The arboriculturist cultivates trees for their esthetic 

 value and their shade, and deals with them only in their 

 living state. To call one in charge of tree culture in a city

 enthusiast in his work and inspire among the people of a 

 community the proper appreciation of the value of trees. 

 The people will then in turn help him in the administration 

 of his office; for his success will largely depend upon- the 

 interest of the people of his town or city in their trees and 

 the support which they give him. He must also appreciate 

 the responsibility of his position as the guardian of one of 

 the chief resources for maintaining the beauty and health of 

 a city.

 of the municipal engineer. It is necessary to enumerate the 

 existing trees, to make layouts for new plantations and keep 

 records of these. In order to care intelligently for his 

 charges the municipal arboriculturist must know how many
