BRITISH FOREST TREES 



From the above it will be seen that the Scots pine reaches 

 its maximum annual and maximum average increment in 

 cubic contents much earlier than the shade-bearing species 

 that do not make great demands on increase of growing- 

 space until the later stage of their development. 



Comparing the average production of timber in forests 

 growing on localities similar as to quality of soil, Gayer 

 classifies the various species of trees in the following order 

 as to general energy displayed in growth of cubic con- 

 tents (pp. til. p. 43) : 



Spruce forest, silver fir forest. 

 Larch forest, Weymouth pine 1 forest, Scots pine forest. 



1 Hurckhardt, Sacn uint 



, 5th edition, 1880, p. 426, says : - 

 In growth of cubic contents the Weymouth pine is surpassed by no 

 ther species of tree, except perhaps the poplar."
