IDS MODERN FOREST ECONOMY. 



Being very resinous, it is often gemme. It is probable 

 that the twisted form of the trunk may be the result of 

 this practice rather than of a peculiar tendency in the 

 tree. 



It is cultivated on the sand wastes of La Sologne, 

 together with the Scotch fir and the Norway fir, after the 

 soil has been previously prepared for this by the previous 

 culture of the Maritime pine. Detailed information in 

 regard to sylviculture in La Sologne are given in the 

 volume entitled Pine Plantations on the Sand Wastes of 

 France (pp. 69-80). 



This tree was introduced into Britain in 1835. It is 

 propagated by seed, and grows on a sandy loam. But 

 mention is made of it here solely to supply a specimen of 

 the instruction given in regard to different kinds of trees 

 in Schools of Forestry on the Continent of Europe.
