- One-half of all the cleared strips was grubbed, plowed deep, and 
thoroughly cultivated before planting, while from the other the trees 
only were removed, leaving all undergrowth. In the last half of April 
the cleared spaces were planted with 1,831 Scotch Pine and 216 Green

land on June 30. In October, at the end of the growing season, 99
