degree, its power of resistance against winds, and its general reli- 

 ability on exposed sites far surpassing those of the other species. 

 It may be added that its virtues are apparently not necessarily 

 confined to its behaviour on hilly sites. 



" It is a noble and ornamental tree for a park and will probably 

 produce, on sheltered places with a moist clay soil, more wood 

 than most other conifers, while for shelter belts and where cover 

 is wanted it may prove in certain districts to be the most valuable 

 member of the whole fir tribe." 



JOHN D. CROZIER. The Sitka Spruce as a tree for Hill plant- 

 ing and general Afforestation. Transactions of the Royal 

 Scottish Arboricultural Society, Vol. XXIII, Part I, pp. 7-16, 

 January 1910, with plate. Edinburgh. 



Amongst the many species of coniferous trees of economic im- 

 portance introduced into Britain from Western-North America and 

 now to be found distributed over the country of an age and in 

 numbers sufficient to test their value for afforestation purposes, 

 none seem capable of producing a growth of timber on high ele- 

 vations, and moisture-holding soils equal in volume and value to 

 that of the Sitka spruce or Menzies fir (Picea sitchensis). 



After a study of the habitat of the Sitka spruce over a wide area 

 and under varying conditions of management, the authors gives 

 the following conclusions: 



1) The Sitka spruce is suitable for afforesting exposed sites, 

 in humid localities, such as occur in various parts of the King- 

 dom, and particularly in the Scottish Highlands. 



2) Grown in high-forest, it has great productive capacity and 

 yields a high quality of timber. 



3) It enjoys practical immunity from attack by insect and by 

 fungoid pests. 



These qualities, combined with the great size it attains, tend 

 to make the Sitka spruce in England what it is recognised to be 

 in its native country : " The largest of all the spruces and of great 

 commercial importance."
