CARE AND CUI.ITVATION. 



Cultivation in this region is unnecessary. Persistent dead 

 branches should be removed when possible, but it is not advisable 

 to prune live ones. When there is a demand for small material, 

 the stand may be profitably thinned, as described in detail, at the 

 age of from 20 to 30 years, removing at the same time all sup- 

 pressed or intermediate trees which are not needed in the stand 

 to shade the ground or to assist in naturally developing the large 

 trees. 



Fire must be kept out of these stands, since the bark of the 

 young trees is thin and easily damaged, and injuries from this 

 source cause rapid decay. 



Information regarding general nursery practice and plant- 

 ing may be obtained from the publications of the Forest Service, 

 which may be procured from the Superintendent of Documents, 

 Government Printing Office, Washington, D. C, for a nominal 

 price. 



Insect damage, if serious, should be reported promptly and 

 specimens of the affected parts sent to the Maine Agricultural 

 Experiment Station, Orono, where they will be identified and 

 measures suggested for their control.
