FORESTRY 



inate here readily and even clean cuttings quickly restock 

 themselves naturally. Soils that are continuously wet and 

 upon which the water stagnates usually are of little value for 

 forestry unless drained. Where water has been dammed up 

 and caused to stand about trees for some time they die. Some 

 •trees seem to stand more moisture than others. The American 

 larch or tamerack frequents moist low grounds. The willow, 

 sycamore, ash, elm, swamp maple, and even white pine are 

 -found here more or less. The spruces, firs, and cedars do well

 easily drained often give valuable tree growth. Forest growth about a

on moist or wet lands. Wherever there is plenty of moisture 

 seeds readily germinate. Many do equally well on high 

 ground. Low or wet lands are usually very rich in plant food, 

 the accumulation of deposits from the higher ground. When 

 this soil is drained or raised it contains valuable elements that 

 become very available as plant food, and trees grow rapidly 

 in it.
