WORLD'S TIMBER RESOURCES 207 



one of the chief industries, and where there are 

 still extensive supplies of second-class timber 

 untouched, it is difficult to induce the public to 

 agree to such restrictive measures as will insure 

 reproduction and continuous supplies. As the 

 natural reproduction of conifers is from seed 

 and the White Pine does not grow as rapidly 

 as some other soft woods, it is plain that sooner 

 or later the strictest protection must be enforced 

 in denuded areas while forests more remote from 

 the settled districts are being worked, in order 

 that fresh supplies may be insured. Under 

 favourable circumstances fairly mature White 

 Pine may be obtained in 40 years, although a 

 •better quality of timber from trees about two 

 feet in diameter may be looked for in 60 to 70 

 years." 



Ontario boasts about 23,000,000 acres of forest 

 land, and despite the very extensive lumbering 

 operations which have been carried on for many 

 years, the province still has very large supplies 

 of merchantable timber. 



" The principal tree of commercial value is 

 the White Pine, the timber of which, in addition 

 to a large consumption in the Dominion, is one 

 of the principal articles of export to Europe 

 and the neighbouring repubUc. It grows both 

 in pineries and mixed with other trees, and is 

 found chiefly in the valley of the Ottawa River
