In the case of yoiin^ stands of 

 mixed species it is desirable to have 

 some knowledge of each species re- 

 quirements in ,reg-ar(l to lii^dit and 

 shade. Take for example a stand of 

 young Avhite pine and hemlock com- 

 ing -up together. The white pine l)e- 

 ing the more valuable it is the tree 

 we desire to encourage the most. It 

 is well, therefore, to know that the 

 hemlock will produce more shade 

 than the white pine, and we must 

 favor the white pine when thinning, 

 tO' encourage it to keep ;diead of the 

 hemlock. Should the hemlock become 

 the_ dominant, or leading tree, the 

 white pine will suffer bv beino; too 

 severely shaded. 



In thinning, select the trees you 

 desire to retain and then decide what 

 trees should be cut to help the ones 

 that are to remain. It is well to thin 

 on the safe side and take out too lit- 

 tle, rather than too much. One can 

 always come back later and remove a 

 few trees if necessary. It is a much 

 more difficult matter to overcome the 

 evil of too heavy a thinning. 



It is a good general rule not to cut 

 a tree if its removal will leave an 

 opening which cannot be closed by 

 the branches of surrounding trees in 

 from three to four years. Begin to 

 thin when the trees are still young, 

 as soon as the lower set of branches 

 havq ; been killed, and repeat this 

 thinning every five or six years. Light 

 thinning every five or six years is bet- 

 ter than severe thinnings made at 

 longer periods. The average wood- 

 lot owner, however, will probably find . 

 it more convenient to begin thinning 

 when the material is of sufficient siz^ 

 to make firewood or be used for some 

 other. purpose.— B. R. MORTON.

YEARS 



rentide Coni])any's nurseries at 

 Proulx, and some (^[ the old cutting 

 operations in ilie Teche district. He 

 has also visited rricc r.rothers and 

 the Belgo-Canadi;iii i ipcrations. Mr. 

 Carbonnier is making a tour of the 

 continent, studying forest conditions 

 for the Swedish fiovernment. and will 

 visit British Columbia, Washington, 

 Oregon, California, the United States 

 National Forests, anrl the Southern 

 Pine Forests. While at the Lauren- 

 tide Company's nurseries he express- 

 ed surprise that woods operations in 

 Canada were not managed by tech- 

 nically trained men. and said that in 

 Sweden all such work was under the 

 direction of foresters. Mr. Carbonnier 

 declared that in Canada we are pass- 

 ing through the same stage of hand- 

 ling our forests that Sweden did fifty 

 years ago. and said that unless a 

 change were made here in the 

 methods of cutting, which he regard- 

 ed as destructive, we would be in a 

 dift'icult position in the next genera- 

 tion. 



Mr. Henrick Carbonnier. honorary 

 attache to the Swedish Consulate in 

 Montreal, has just visited the Lau- 



TIMBER SCARCITY? SURELY NOT. 



Canada has burned down, through public indif- 

 ference, 437 times as much timber as was cut in 

 the whole of Canada in 1919. 



And how much was cut last year? 



Enough to make new wooden houses for one 

 million Canadians.
