NOTES 741 



American forester knows, the Government does not possess within its 

 National Forests in northern California any areas of redwood where 

 the Sequoia scmpcrvirens is to be found. Perhaps it is not generally 

 known, however, that when it was found that the $50,000 set aside by 

 the Federal Government for the purchase of a forest of Sequoia wash- 

 ingtoniana was insufficient, the National Geographic Society contrib- 

 uted the balance of the money, thus preserving these magnificent trees 

 for all time. 



The movement to obtain possession of this tract of redwood for the 

 nation has been under way for some time and we wish the imdertaking 

 all success, for it would be not less than a crime to leave these forests 

 wholly in private hands, where in time they are sure to be sacrificed to 

 the lumberman's axe. 



The Canadian Forest Products Laboratories and Department of 

 Mines have investigated the applicability of various wood oils to the 

 flotation process of recovering silver and other metals to make the 

 Dominion independent on supplies from the United States. While 

 from red pine and western yellow pine as serviceable oil could be 

 secured as from southern pine, it would be too expensive on account 

 of the small quantities recovered and no market for the by-products is 

 in existence. Creosote oils from hardwood distillation, now burned 

 under the boilers as waste product, were also found serviceable, and as 

 there are about 1,200 gallons daily produced, there is more than enough 

 of this product for present requirements. 



One of the wisest and most beneficial steps taken lately by the Bureau 

 of Forestry at Manila was the revival of the foresters' conference. 

 During the middle part of the administration of Major Ahern, of the 

 Bureau of Forestry — that is, between 1905 and 1910 — the foresters 

 were usually called from the field to Manila for an annual conference, 

 but from 1910 up to 1917 this practice was discontinued, and was not 

 revived until 1918. On November 13, 1917, a letter was sent to all 

 the districts notifying the different officers in charge that they would 

 be called to Manila for a conference during the latter part of January, 



Trees planted by dynamite show more growth than those planted by 

 pick and shovel. In a particular case dynamite was used to overcome 

 obstacles such as roots of pine trees 150 years old, between which the
