1918 



Canadian Forest rij Journal, November, 1918 



cold weather without thaws or moist 

 air, the trees steadily lost moisture 

 until they lost too much to recover. 

 The fact that trees lose moisture in 

 winter has been proved by analysis 

 of twigs. Sudden low drops in tem- 

 perature may also have caused part 

 of the injury. 



Reports were received of Sugar 

 Maples being killed in the province of 

 Quebec and other native trees, in- 

 cluding White Pine, being injured or 

 killed. In some cases the leaves of 

 the ])ines were killed but the buds 

 remained alive and new leaves de- 

 veloped. 



At the Experimental Farm, Ot- 

 tawa, trees native of South Western 

 Ontario, such as, Sweet Chestnut, 

 Tulip Tree, certain species of Oak 

 and Honey Locust were killed or 

 badly injured, and, among pines, 



the Bull Pine of British Columbia 

 suffered considerably. Among ex- 

 otic trees, the Oak, Elm, Ash and 

 Horse Chestnut were among those 

 badly injured. 



Hardy Apple Trees Died. 

 It was noticed, amohg apple trees 

 particularly, at Ottawa, that some 

 of the hardiest varieties were killed. 

 In most, if not all of such cases, the 

 trees had made little growth the 

 previous year, or had borne a large 

 crop of fruit, with the result, in our 

 judgment, that they were very low 

 in sap when winter set in. Other 

 less hardy varieties, which were killed, 

 had made good growth the previous 

 year. In many cases the trunk and 

 lower parts of the main branches were 

 the parts killed, the younger branches 

 remaining alive until there was no 

 sap to support them. 



Logging Engineering and Forestry Practice 



By Dr. JiDsoN F. Clark, Vancouver 



Until such time as lumber prices 

 substantially and permanently ad- 

 vance, the main hope of bettering 

 forest finances and thereby widening 

 the field where forestry may be 

 practised, rests in the lowering of 

 the costs of marketing the forest crop. 



Logging engineering is at present 

 our best hope for the larger stumpage 

 returns so necessary for the extension 

 of forestry methods. In the past it 

 has been developed almost entirely 



by practical men who have had but 

 limited opportunity to know and see 

 what the other fellow was doing, y 

 For the future, the forest schools >" 

 should become clearing houses foi- 

 information discovered and better 

 methods developed all along the line 

 and thus become at once the source 

 of supply for our specialists anf the 

 training ground for our every-da\' 

 foremen loggers.

Switzerland's Forests Worth £58,000,000 



The value of the Swiss forests, 

 calculated on a 3% yield, is over 

 £58,000,000, or about the total of 

 the debt for the federal railways at 

 the end of 1915, whereas there are 

 only 200 ofTicials to administer the 

 public forests, which have a minimum 

 I value of over £26,000,000. 



MUCH B. C. SPRUCE LEFT. 



In response to the fears expressed 

 that the large amount of spruce being 



cut for the Imperial Munitions Board 

 for aeroplane construction would de- 

 plete the spruce forests of Northern 

 British Columbia, it is authoritatively 

 stated by the Department that at 

 the present high rate there is enough 

 spruce in the limits now being worked 

 to last for two years, andthat there is 

 not the least doubt that very consid- 

 erable stands of suitable timber can 

 be located to provide an even larger 

 output if necessary. -A'ancouver "In-
