as a pure crop, they should be notched into the ground at from 

 4 to 4^ feet apart. If mixed, the best species to associate with 

 it ai-e beech and Douglas fir, but beech is the better of the 

 two. In this case plant alternately at 5 feet intervals. In 

 planting larch, the greatest care should be taken that the young 

 trees are not injured by the heel of the planter's boot coming in 

 contact with them when firming the ground. 



Scots fir thrives best on light sandy or moorish soil which has 

 been previously drained and freed from all stagnant water. For 

 growing on heath-land it is the most reliable of all our timber 

 trees. Unless the surface of the ground is coated with rough 

 heather or weeds which cannot be burned, the best plants to use 

 are two years bedded, one year transplanted. If the ground is 

 rough, then use plants two years bedded and two years trans- 

 planted. Put in the plants at intervals of 3 feet, and use the 

 T notch system. This species should always be planted as a pure 

 crop. 



Norway spruce grows to perfection in moist hollows, at the 

 foot of glens, and alongside water-courses, although it will often 

 grow to a profitable size on comparatively high ground which has 

 a free subsoil. Avoid planting it on exposed situations, as, 

 owing to its shallow root system, it is easily uprooted by gales. 

 Use plants which have been two years bedded, and two years one 

 year transplanted. Notch or pit at intervals of i feet. This 

 tree does best when planted in bulk by itself. 



There are other species, such as the Douglas fir, Thuja gigantea, 

 Abies grandis, etc., well worthy of notice, but those which have 

 been dealt with are the most reliable kinds for planting for 

 economic purposes.
