 management is required to prevent it from becoming a mere rule 

 of thumb. 



It is hoped that the Forest Service will publish other mono- 

 graphs like this circular. Like the monograph on the Douglas 

 Spruce by Mr. Frothingham, the Paper Birch in the North-East

Farm Forestry. By Alfred Akerman. Published by the 

 Georgia Forestry Association, Athens, Ga., 1909. Pp. 22.

The report contains also the laws of New Jersey relating to 

 shade trees. 



It would have been very useful if there had been included in- 

 formation regarding the proper organization by a town or city 

 of the work of the care of the shade trees. The municipality
