" Of all the trees of eastern North America white pine best combines the quali- 

 ties of utility, rapid growth, heavy yield, and ease of management." Besides his- 

 torical matter, the chief stress of the bulletin is upon management, which will 

 not only tend to the preservation of existing stands of pine trees but also to the 

 production of others from seed. Tables show the value of stumpage at prevailing 

 prices and the profit or loss resulting from the management of second growth 

 under favorable and unfavorable conditions. Methods are also suggested for 

 securing successive crops and for increasing the quantity and quality of the yield.
