INVESTIGATIONS IN WHITE PINE PLANTATIONS.

MEASUREMENTS. 



Table 11 represents the most thrifty and fastest growing planted 

 white pine known to the writer. The grove is only 15 years old, 

 yet most of the trees range from 21 to 36 feet in height. The rate of 

 growth in height has varied from an average of 1 foot to 2.4 feet per 

 year for the entire period of growth. Table 12 shows the relative 

 growth of the European larch when planted in mixture with white 

 pine in alternating rows.
