Research Council and Reforestation 



Sir (ieoiiJio I'Vjster, on ^^a\' 17lh. 

 tabled in the House of Commons a 

 report by Prof. Macallum, admin- 

 istrative chairman of the advisbry 

 rommittee on scientific and indus- 

 trial research. The report, which is 

 'a voluminous affair, covers the var- 

 ious branches of enquiry instituted 

 and carried on by the advisory 

 council since its appointment. 



There are some interestini^ refer- 

 ences to the work done by the com- 

 mittee which enrpiired into the cfues- 

 tion of the growth and reproduction 

 of the forests of Canada, more par- 

 ticularly those of the eastern pro- 

 vinces. In regard to this matter, 

 the report says: 



"The research council is of opin- 

 ion that this investigation of the 

 gro\\-th and reproduction of our for- 

 est trees, thus inaugurated and con- 

 tinued, will, in a few years, enable 

 the forestry denartments of Dominion 

 and provincial Governments to in- 

 augurate, on a scientific and prac- 

 tical basis, a scheme of reforestation. 

 \\hich will parallel the l)est results 

 obtained in the past in Europe, and, 

 in consequence, preserve for Canada, 

 one of her greatest and enviable re- 

 sources, now in danger of extinction, 

 because of reckless waste, and of the 

 almost entire disregard of any system 

 required for its prevention."

 DANGER TO WHITE PINE 



i 'Editor, Canadian Forestry .Journal. 



I beg the privilege of calling your 

 attention to a short article on page 

 1153, December Number, with the 

 lieading "White Pine Immune In 

 N. B.." since the headlines unfortun- 

 ately carry an erroneous impression. 



Probably this has been called to 

 >(nir attention by some of your own 

 l)lant pathologists, and it may be 

 well and desirable to correct in 

 another issue the impression which 

 might have been gained in the minds 

 of \our readers, that New P>i-iins\\ ick 



white i)ine is immune from this ex- 

 tremely dangerous disease. Appar- 

 ently you desired to convey the idea 

 that the disease had not yet been 

 discovered in this province, but most 

 assuredly the white pine species, 

 wherever it grows, is not immune 

 from the disease. We have the pro- 

 blem \\\{\\ us in Pennsylvania, and I 

 am exerting my utmost effort to hold 

 it in check, and, fortunately, last 

 year by very early and thorough 

 eradication of infected pines, we pre- 

 vented as far as we could determine 

 by inspection in over half of the 

 counties of the state, including over 

 two and a fourth millions white pines, 

 and over one hundred thousand 

 separate currant plants, the spread 

 of the di.sease from the pines to the 

 currants. This fortunate situation, 

 I fear, can not last long, even with 

 the most careful inspection.

LONGEVITY OF TREES 



Regarding the longevity of Euro- 

 pean trees recent information gather- 

 ed by the German I'orestry Com- 

 mission assigns to the pine five 

 hundred and seven hundred years as 

 a maximum, four hundred and 

 twenty-five years to the silver 11 r, 

 two hundred and seventy-five years 

 to the larch, two himdred and forty- 

 five years to the red beech, two 

 hundred years to the birch, one 

 hundred and seventy years to the ash. 

 and one himdred and thirty years to 

 the elm. The heart of the oak begins 

 to rot at the age of three hundred 

 years. A sequoia gigantea, felled in 

 Calaveras county, California, had 

 attained the age of three thousand 

 years. It was three hundred and 

 eight>-seven feet in height, and 

 measured fifteen feet in diameter, one 

 hundred and twenty-five feet above 

 the earth. The Bradburn yew, in 

 Kent county, England, had attained 

 the same great age.
