128 FOEESTEY WOEK 



It has been very successfully tried on Sir Eonald 

 Munro-Ferguson's estate at Novar in Eoss-shire, and is 

 described at some length by Mr. W. McKenzie in the 

 " Transactions of the Eoyal Scottish Arboricultural 

 Society" for January, 1910, vol. xxiii., part 1, page 35: 



" The Larch are planted pure. When they reach the 

 age of from 12 to 15 years the diseased stems are cut 

 out, leaving only the soundest and healthiest, which 

 usually number from 350 to 600 per acre. 



" They are underplanted with two-year seedlings, 

 dibbled in at the rate of about 2,000 per acre. The species 

 used are Sitka Spruce, Thuja gigantea, Tsuga Alhertiana, 

 Abies grandis, Cupressus Lawsoniana, C. macrocarpa, 

 C. Sempervirens, Ahies nohilis, A. Concolor, Norway 

 Spruce, Silver Fir, Douglas Fir, and Beech." 



When a small proportion of a crop is to be left for 

 a second rotation, the gi'ound is planted up, with shade- 

 bearing trees under the dhect shade and drip of the 

 standards, and groups of light-demanding trees in the 

 more open spaces. 



The Time to Plant or Sow. 



In districts that are subject to a dry, cold spell during 

 April and May, it is better to start planting in autumn, 

 so that the plants may get the advantage of the winter 

 rains and snows. 



Hardwoods, as a rule, should be planted in autumn, 

 as their rootlets will grow during any open spell during 

 the winter, and the trees start into growth more readily 

 than when planted in the spring.
