EXPERIMENTS IN IMMATURE WHITE PINE STANDS. 



These experiments were started in 1912 when twenty-nine plots were 



estabUshed to determine best methods of thinning immature white pine stands. 



The plots are measiu"ed annually, and the following results are now apparent: 



(a) "\Miite pine is seriously checked by overtopping hardwoods except, per- 

 haps, gray bii-ch. 



(b) The removal of these overtopping hardwoods leads to an immediate 

 increase in gro-niih, provided it is not delayed too long. 



(c) Data is being secured on the cost of such thinning at different ages. 



(d) Pure stands of white pine are also being thinned and the cost (net and 

 gross) determined at different ages.
