CORSICAN PINE 409 



Corsican and Scots Pines may be evenly mixed when 

 the success of the Corsican Pine is doubtful. 



Corsican and Weymouth Pines make a good mixture in 

 cases where the success of a pure crop of Weymouth Pine is 

 doubtful. The Corsican Pines must be removed as thinnings, 

 for the Weymouth Pines will surpass them. 



Corsican Pine and Douglas Fir is an admissible mixture 

 where a final crop of Douglas Fir is desired, and the expense 

 of planting a pure crop is considered too great. 



Rotation. The best rotation is about 80 years, though, 

 as with most coniferous crops, quite short rotations often pay 

 very well for pit timber. 



Average returns from pure crops in high forest should 

 be, per acre : 



Thinnings . . . 1680 cub. ft. to 2 in q. g. 

 Final yield (at 80 years) . 3600 6 

 Total production . . 5500 2 



Average annual increment, 75 cub. ft. 



Of Fungi and Insects. The fungous and insect attacks 

 are similar to those mentioned as affecting Scots Pine. 



Of other Pests. Rabbits, usually, will not persistently 

 attack Corsican Pine. But, in hard winters, if they can find 

 nothing else to eat, they will readily feed on the bark. 



In cases where only a few Corsican Pines have been 

 planted, they are often attacked by rabbits, who, out of 

 ignorance, like to sample the bark, but soon come to the 

 conclusion that it is distasteful. 



Squirrels do much harm by " ringing " the trees near the 

 top. 



THE STAR, CLUSTER, OR MARITIME PINE. 



This is not a native tree, and is said to have been intro- 

 duced in 1596. 



The timber is coarse, resinous, and rather heavy. It is 

 very inferior to Scots Pine timber. The tree never grows 

 with a straight bole. 



Soil and Situation. It prefers deep, dry, sandy soils;
