A MAM'AL OF FORESTRY 



Maple Sugar and Syrup. Vermont, New York, and New 

 Hampshire are among the six leading states of the country for 

 the making of maple products, and in certain sections these are 

 important factors in woodlot management. Maple sugar is 

 formed from starch, which is formed in the leaves under the 

 influence of sunlight and stored in certain sapwood cells. The 

 best sap flow occurs in the early spring when there is an alterna- 

 tion of cold nights and warm days. Three pounds of sugar per 

 tree is a good, although not extreme, yield. Sugar is worth from 

 10 to 25 cents a pound, according to the quality and way it is 

 put up. 



There is little use in stating prices paid for different materials, 

 since they vary so considerably from year to year. The follow- 

 ing prices are, therefore, included not for the sake of indicating 

 what any particular material will sell for, but to show the relative 

 value of logs and wood for different markets. The prices given 

 below are for logs delivered at the mill, or for wood delivered to 

 the consumer.
