108 FOKESTRY WOKK 



Fir, Thuja gigantea, and Cupressus Lamoniana. Pines 

 will do well on a short rotation. 



Medium Loams and Loamy Sands: Practically all 

 trees will grow well on these soils, but the main crop 

 should be Oak, Spanish Chestnut, Sycamore, Elm, 

 Douglas Fir, or Larch. 



Sandy Soils: The Pines (Scots, Corsican, and Austrian), 

 with Birch. 



Gravels: Beech, Sycamore, Maple, Sessile Oak. Where 

 there is a good supply of moisture, Douglas Fir, Larch, 

 Poplars, and Willows. 



Chalky Soils: Birch, Beech, Larch, Silver Fir, and 

 Thuja gigantea. (Spanish Chestnut, Sycamore, and 

 Weymouth Pine, should seldom, and Douglas Fir never, 

 be planted on limy soils.) 



Peaty Soils: Wych Elm, Beech, Larch, Scots, Corsican, 

 and Austrian Pines. As a rough guide it may be said 

 that heavy soils should be planted with hardwoods and 

 sandy soils with conifers. 



Frosty Hollows : The Scots Pine is our hardiest conifer, 

 and the most frosty places should be planted up with 

 this tree. The other pines are also fairly hardy. Birch, 

 Hornbeam, Poplars, amongst the hardwoods, stand frost 

 best. 



Trees suffer most from frost in the early autumn, 

 before the young shoots are properly ripened, and in 

 late spring, when they are beginning to shoot. 



Frost does most damage in those places where the 

 air-currents have not free play, such as in valleys or 

 Depressions of any kind, and on southern aspects
