 DURABILITY. 



With regard to its durability, White Pine is generally underrated. The soft, light-colored 

 wood suggests general frailty and a lack of resistance, in which resistance to decay is included. 

 In the region where it grows the unusual great durability of the heartwood of White Pine is 

 well known; "the stumps of White Piue last a lifetime;" old logs, covered with moss and often 

 with young Poplars and Birch growing from their surface are uncovered and utilized as shingle 

 bolts. White Pine shingles wear out, but rarely decay, and a good sidewalk of White Pine is 

 considered the best to be had. As in other pines, the sapwood decays readily, but this being 

 narrow in good logs, more than half of all White Pine sawed is good durable heart, a wood which 

 is neither subject to decay nor to the boring insects any more than the heavy resinous heart of 

 the Bed Pine or of the Southern pines. 



COMPARISON WITH OTHER WOODS. 



Generally White Pine is logged and milled on a large scale, cut mostly into boards and plank, 

 and there is to-day no common wood which is more economically handled and more carefully 

 selected. 



Compared to other pines, the White Pine is offered more extensively and has a greater 

 influence on lumber markets than any other wood used. It is more uniform, lighter, softer, and
