themselves readily of limbs and develop straight trunks of 

 good diameter. The wood is straight-grained, of moderate 

 weight, strong, and makes a very satisfactory lumber. The 

 Austrian pine is well adapted to planting in woodlots through- 

 out the eastern half of the state. 



Habit of Growth. The Austrian pine is an intolerant 

 species, and must be planted in open situations where it will 

 receive full sunlight. It attains its best growth and develop- 

 ment in deep, rich, rather moist but well-drained soils. It 

 grows remarkably well on light sandy soils or on thin gravelly 

 clay soils, but on the latter types of soil its rate of growth is 

 considerably slower than on the bottom type. 



Three- and four-year-old seedlings of this species, which will 

 range from 15 to 18 inches in height, should be planted in pure 

 stand, either on any cleared land or on old tilled fields or oh 

 steep gravelly or stony hillsides. These seedlings should be 

 spaced approximately 6 by 6 feet, which will require 1200 

 seedlings per acre. They will demand the same general care 

 and attention that is required by other trees. By the time the 

 trees reach middle age it will be necessary to do considerable 

 thinning, at which time the inferior specimens should be re- 

 moved. This cutting will yield considerable fuel, and perhaps 

 some poles that can be utilized for other purposes. The final 

 stand will reach maturity when from sixty to seventy-five 

 years of age. 



Yield. The ultimate cut will be sawlogs that will measure 

 from 18 to 35 inches at the stump. In good situations the yield 

 should approximate 15,000 to 18,000 board feet per acre. In 

 European countries the Austrian pine figures extensively in 

 the turpentine industry. The bleeding is continued over a 

 period of twelve or fifteen years prior to' the maturity of the 

 crop and final cutting. 



The Austrian pine is absolutely free from injurious insects 

 and fungous diseases, and no objection can be raised to its 

 use from these standpoints. The greatest objection at the 

 present time to its use in the woodlots is the high cost of the 

 planting stock. 



Sugar Maple. 



The sugar maple is a native tree along the eastern border of 

 the state, and grows with much vigor on the rich, deep soils
