loam. The bundles should be untied before placing them in 

 the pail. Sod should not be replaced, and each tree should be 

 firmly set by pressing the earth about it with the foot. An 

 experienced two-man crew can plant from 800 to 1,000 trees 

 per day. 



SPACING. 



The best practice is to space the trees 6 feet apart each way. 

 This method produces a tall, straight bole and prevents undue 

 spreading. Flags may be set up at the end of the field as a 

 guide to the crews, and moved over 6 feet as the end of the 

 course is reached. 



On moist situations Norway spruce or balsam fir may be 

 planted alternately with white pine. If the pine is set 6 by 

 6 feet, and the fir or spruce set in the centers of the squares 

 thus formed, the trees will be evenly spaced 3 feet apart. In 

 from eight to ten years the fir and spruce will yield an inci- 

 dental revenue if cut and sold as Christmas trees. It has the 

 added advantage of rendering a plantation comparatively safe 

 from any local disease or insect attack that may seriously de- 

 plete any one of the species used. And in this connection it 

 may be said that the forest planter would do well to use at 

 least two species of trees, even in the 6-foot spacing. When 

 planting pine the combination recommended is white pine, 

 alternated with red, Scotch or Austrian pine. Spruce may be 

 alternated with hemlock, tamarack or balsam fir.
