SYLVICULTURAL NOTES ON SCOTCH PINE. 299 



Silver Fir woods, also with Weymouth Pine and Spruce. 

 It holds its own against these. In the moist climate of 

 Britain it is also grown in mixture with Larch and 

 Oak. It may be usefully underplanted with Silver Fir, 

 Beech, Spruce and Douglas Fir, to which it affords a 

 suitable shelter. 



g. Sylvicultural Systems. 



Scotch Pine is generally treated as high forest with 

 clear cutting, exceptionally only under the shelter- wood 

 systems. It is well suited for standards in high forest, 

 as well as in coppice. It is extensively grown as a 

 shelter-wood for frost-tender species. 



h. Formation of Woods. 



Scotch Pine may be sown or planted on clear cuttings, 

 or regenerated naturally, either under an open shelter- 

 wood or on cleared areas from adjoining woods. Planting 

 is the usual method. No shelter is required by the 

 young plants. 



The seed ripens in October of the second year, but 

 does not fall until the following spring, so that in 

 autumn three kinds of cones may be seen on the trees, 

 namely, six months old unripe cones, 18 months old 

 just ripe, and empty cones of the previous crop. The 

 germinating power is maintained for 2 or 3 years. Of 

 good seed at least 70 per cent, should germinate. One 

 pound of seed contains about 70,000 clean grains. 



Direct sowings should be made in spring, the seeds 

 being covered by about half-an-inch of earth. About 

 six pounds of seed are required per acre for broadcast 

 sowing ; it germinates after 3 or 4 weeks.
