It has been estimated that white pine planted on sandy waste 

 lands in Ontario will yield, in sixty years, two hundred (200) trees 

 averaging eighteen (18) inches in diameter, or about eighty thousand 

 (80,000) board measure, per acre. In this estimate the land was 

 valued at $5.00 per acre; taxation figured at 17 mills; the cost of plants 

 and planting $10.00 per acre; the cost of management and protection 

 at 15 cents per acre per year and the rate of interest charged was 3^%. 

 The total cost worked out to $165.34 per acre. This does not include 

 the thinnings which would probably yield a revenue after the twen- 

 tieth year and somewhat reduce the cost. 



Sugar maple grown under normal forest conditions would yield 

 from one hundred and fifty (150) to one hundred and seventy-five 

 (175) per acre having an average diameter of eighteen (18) inches 

 in about one hundred and fifteen (115) or one hundred and twenty 

 (120) years. Provided all the other items, i.e., cost of land, taxes, 

 etc., were the same, this increase in the length of time alone would 

 raise the cost of growing maple considerably above that of growing 

 pine. The cost of the plants and planting would probably be 50% 

 more than the $10.00 figured on for pine. This is partly due to the 

 heavier nature of the soil in which the maple would be planted and 

 partly due to the higher price for maple seedlings. 



It would appear then that if the price of white pine and maple 

 lumber keeps the same relative position (about equal in 1911), it would 

 hardly be a paying proposition to grow maple for lumber alone. How- 

 ever, when one considers the revenue derived after the thirtieth year 

 from the sap and the higher price obtainable for thinnings as fuel, 

 or making acetic acid, wood alcohol and charcoal, there seems but 

 little doubt that the maple would in the end be the more profitable 

 tree. This is particularly true in case of the small woodlot owner 

 or farmer, who has many uses for the wood, and especially where the 

 maple already exists in the stand and natural reproduction can be 

 secured.
