will be of any value for forest planting.

Examples 60-90 ft. high are fairly common, though there are 
many trees that develop in width at the expense of height. The 
branches are more or less horizontal, and as the lower ones grow 
rapidly in length and diameter, a tree of no great height may 
cover a wide area of ground. The abnormal development of @ 
few branches may affect the strength cf the trunk, and it 38 
not uncommon to find trees with very thin and weak tops, 
although the branch system of the lower parts of the trees may 
be strong and vigorous. It is also liable to form several leaders, 
therefore a strict watch should be kept upon young trees an 
rival leaders, and very vigorous branches checked in the early 
stages. Exposure to violent winds appears to injure the uppet 
finer specimens than others that are moderately exposed. AS 3 |
