1 Difficult to transplant on account of tap root. Advisable to sow seeds in permanent 

 sites in field whenever possible. 



Note on the conifers (Mulford). White pine, Scotch pine, and Norway spruce seed should 

 be collected as soon as it is ripe, in September. The cones should be dried, allowing the 

 seed to fall out. The seed should be stored for the winter in bags hung in a dry, cool 

 place, and should be sown thickly in the spring, covering with about one-eighth inch of soil. 

 From 60 to 90 per cent of the seed should germinate. One-year-old seedlings are from one 

 and one-half to three inches high. 



Forest planting (Mulford). 



Forest planting is usually done with the mattock (grub hoe). A 

 space about twelve to sixteen inches square should be cleared of all 

 growth, and a hole dug in the middle of this large enough to receive 

 the roots comfortably. Another method is to plow and harrow the 

 ground, mark out with a corn marker, and simply set the tree in a 

 slit pried open with a common spade, the slit being closed by a second 

 thrust of the spade. By the former method, from 250 to 600 trees 

 per day per man can be planted ; by the latter method, from 800 to 

 2000 trees. Forest trees are ordinarily planted 4 X 4, 5 X 5, or 6 X 6 

 feet (i.e. about 2700, 1750, and 1200 trees per acre, respectively), the 

 closer spacing being more necessary with slow-growing trees and on 

 poor soils.
