Weed Trees. 



Just as weeds come in the garden to 

 choke out the plant growths that 

 were wanted, there are certain forms 

 of forest growth that are undesirable, 

 or at least less profitable. In the case 

 of cedar, for instance, it is difficult 

 to get new cedar growths without 

 having them crowded out by hem- 

 lock. The problem is to get the one 

 without the other. Jack pine is a 

 prolific weed in the forest. In size 

 it is only good for railway ties or 

 mine props, yet its thick growth has 

 monopolized much land that might 

 be bearing good yellow pine, spruce, 

 fir or larch. A great deal might 

 be done to encourage the growth of 

 the western soft pine in the interior 

 and the perpetuation of the valuable 

 Sitka spruce was a matter about 

 which very little is known at the 

 present time. 



Stock- Taking. , 



"It can thus be seen that there is an 

 immense field for important work to 

 be done in the forestry service. Not 

 the least important work should be 

 the stock taking of our forest re- 

 sources so that we may know the 

 facts about the present timber crop 

 and about the timber that is growing 

 up to take its place. Land suited 

 for agriculture must be located and 

 separated from the areas that should 

 be set aside for the perpetual grow- 

 ing of timber because they will not 

 grow anything else. 



"The development of British Col- 

 umbia forestry will depend on techni- 

 cally trained men," said Mr. Grainger 

 in conclusion, "and some means of

training these men must be provided. 

 At present our boys must go back 

 east or to the Uniled States to get 

 their training. The British Colum- 

 bia university — which provides train- 

 ing for teachers, for mining and civil 

 engineers, for agriculturists — will not, 

 I hope, remain long without a forestry 

 school for training men to handle one 

 of the biggest natural resources that 

 any country has ever had." 



DOES BARK SCRAPING HELP? 



The following question and answer 

 from "American Forestry" will in- 

 terest many readers: 



"Q. I wish to obtain your opinion 

 relative to the practice, now so com- 

 mon, of scraping the outer bark from 

 our shade trees for the purpose of 

 removing scale and other insects, and 

 furnishing no places for their conceal- 

 ment. Many of our most beautiful 

 shade trees, generally elms, have been 

 given this treatment and occasionally 

 the trunk is afterwards painted with 

 some insecticide. All this operation 

 entails great expense to the tree own- 

 er. Personally I have been opposed 

 to this treatment of trees, but I would 

 appreciate a discussion from you on 

 the subject. — W. W. M., Chicago, 

 Illinois. 



"A. There is no justification for 

 the practice of scraping the bark of 

 shade trees. It does no good and 

 sometimes does harm and many 

 varieties of shade trees, such as Nor- 

 way maples, Oriental planes, etc., 

 very seldom have any scale insects 

 on their trunks. If you spray the 

 infested trees with oil solution at the 

 proper time, especially when the 

 young scale insects hatch and become 

 active, you will generally catch most 

 of the insects, no matter where they 

 are — under the loose bark or on top 

 of it. Scraping off the old bark ex- 

 poses very suddenly the young, ten- 

 der bark underneath to sun, heat 

 and dust and smoke, and produces 

 better bait for scale insects than the 

 old bark because scale insects prefer 

 to live on young, tender bark. We 

 think that if you would allow nature 

 to take care of the loose, superfluous 

 bark and not scrape it off premature- 

 ly, the trees would be better off."
