greater part of the war period more ships were 

 being used for timber than for any other British 

 import, and this continued long after American 

 wood cargoes were cut off. Canada, therefore, 

 fore, was obHged to content herself with send- 

 ing forest labor in place of forest materials. 

 The exceptions are to be found in a consider- 

 able export from Canada of chemical deriva- 

 tives, such as acetone, used as a solvent for the 

 fibres in high explosives, and the Imperial Mun- 

 itions Board's demand for 125,000,000 board 

 feet of Sitka spruce (picea sitchensis) for aero- 

 plane construction. (Only 15 to 20 per cent of 

 a spruce log is accepted for this purpose.) 

 There has been at least one other tangible con- 

 tribution to the Imperial cause: I refer to the 

 undoubted development of public sentiment on 

 forest conservation, the new determination of 

 the Governments to antidote the havoc of forest 

 fires, and the slow dawning — not more as yet — 

 of the rudiments of sylviculture in treatment of 

 forest properties. 



Meanwhile the past attitude towards Forestry, 

 or "conservative lumbering", of most wood- 

 using industries in Canada may be summed up 

 in the old phrase, "Say nothing but saw wood". 

 Much wood has been sawn, without doubt. The 

 country has dipped deep into capital account 

 and imperilled the sources of future interest. In 

 a broad sense, this was inevitable. The forests 

 have fallen victim to spread-eagle estimates, in 

 which the lumberman was victimized quite as 

 much as the public administrator. Scarlet cal- 

 culations were wholly unopposed until very re- 

 cent years; need one be surprised that public 

 and private forest policies dragged at the tail 

 of the procession? Our pioneer fathers' enmity 

 for the blockading tree trunks stuck fast. We 

 were at no time world travellers and students 

 of foreign procedure. We did not see that 

 timber possessions attend the highest state of 

 civilization, and in the most efficient nations of 

 Europe are the more jealously guarded as 

 pioneer days recede.

WHAT IS FORESTRY? 



"This field of management of forests for con- 

 tinuity of crop passes under the name of For- 

 estry. Forestry is merely the business of hand- 

 dling timberlands in an improved way for per- 

 petual revenue. It is often considered antagon- 

 istic to the lumbering business, but this is 

 erroneous, because forestry is completely de- 



pendent on lumbering. Its intensity of prac- 

 tice is in direct co-ordination with the status 

 of that industry. It is regulated lumbering, 

 lumbering so regulated with the aid of tech- 

 nical knowledge that the forest may produce 

 revenue forever." — J. H. White, M.A., S.Sc.F., 

 in "Forestry on Dominion Lands." 



HOW TO PRUNE YOUR TREES 



Always use a pole saw and pole shears on 

 the tips of the long branches. 



Do not "head back" or cut off the top of a 

 tree except where the tree is old and failing, and 

 then under special instructions. 



Be as sparing and as judicious in pruning as 

 possible, and do not raise the branches so high 

 as to make the tree look like a telegraph pole. 



Commence pruning the tree from the top and 

 finish at the bottom. 



Make every cut as close and parallel to the 



trunk as possible. 



To make the cut perfectly smooth the saw 

 must be well set and sharp. 



Leave no stubs, dead and dying wood, or 

 fungus-covered branches behind you. 



Do not fail to cover every wound with coal 

 tar, not allowing it needlessly to run down the 

 trunk. 



Do not remove several large branches on one 

 tree at a time. They must be removed gradu- 

 ally, the work extending over several seasons.
