From these tables the timber owner can 

 find the exact financial gain in waiting for 

 his timber to grow to any given diameter, 

 the interest his forest is earning on its cost, 

 and similar valuable information. The 

 tables are now complete for the so-called 

 Adirondack hardwoods, including Yellow 

 Birch, Sugar Maple, Beech, Basswood 

 and Cherry. 



These hardwood tables are based upon 

 analyses of 1000 felled trees and upon 

 actual measurement of the merchantable 

 timber upon 1000 acres. 



its true value before the public, logging 

 methods may be modified, and even if the 

 market develops slowly, there will be a 

 greater effort to prevent waste. 



An important feature of this investiga- 

 tion will be to ascertain the rate of growth

and the time required to produce a mer- 

 chantable stand. The western Hemlock 

 possesses remarkable powers of reproduc- 

 tion and may be counted on to reforest 

 logged-off areas. 



A Study of Hemlock. 



The western Hemlock is to be the sub- 

 ject of a special investigation this summer 

 by the Division of Forestry and a party of 

 experts will spend several months in the 

 Puget Sound region making observations 

 and measurements of that speeies of Hem- 

 lock. 



Although one of the largest and most 

 widely distributed trees in the Pacific 

 Northwest, it suffers from the prejudice 

 against the eastern Hemlock, a closely 

 allied, but much inferior species, and for 

 this reason has almost no commercial 

 value. It grows at its best on the cool 

 damp slopes of the Washington and Ore- 

 gon mountains, where it is frequently 200 

 feet high and 10 feet in diameter, or even 

 larger in favorable situations. It occa- 

 sionally forms a dense, pure forest, but is 

 more often mixed with Red Fir, the most 

 important timber tree of the Northwest, 

 and is usually left standing by the lumber- 

 men because there is no sale for the lumber. 



The wood of the western Hemlock is 

 less apt to be shaky, is stronger, more 

 durable, and more easily worked than 

 that of the eastern species. The bark is 

 said to contain much more tannin. 



By the present method of lumbering, 

 immense quantities of Hemlock are de- 

 stroyed annually, for it is left to be 

 burned by the fires which frequently 

 follow the removal of the Fir. It is be- 

 lieved that if this Hemlock can be given 



Tree Planting Plans. 



A plan has been arranged by which the 

 section of Tree Planting of the Division of 

 Forestry will combine lecturing with its 

 practical field work for the purpose of in- 

 teresting the public in the subject. When 

 an official of this section of the Division is 

 called to any portion of the United States 

 where planting is especially desirable, he 

 will arrange for a series of meetings of 

 land-owners, to whom he will explain the 

 objects of the Division and the free assis- 

 tance offered to those desirous of making a 

 trial of planting. 



The Forest Exhibit at Paris. 



The exhibit of the Division of Forestry 

 for the Paris Exposition is now complete 

 and on the way to Paris. It will be one 

 of the most novel of the Government ex- 

 hibits and will.be whollv distinct from the 

 commercial features of lumbering to be 

 shown in another department. 



The display will be in the form of an 

 angled corridor, the walls of which con- 

 sist of large transparencies illustrating 

 American forest conditions. These walls 

 will be double and illuminated by interior 

 electric lights. The pictures range in 

 size from 3 by 5 feet to 4 by 6 feet. There 

 will be two transparencies 6 by 10 feet, 

 portraying groves of Red Fir and Cali- 

 fornia Bigtrees, two of the most impres- 

 sive American trees. 



A point will be made of the relation of 

 forestry to agriculture, and such subjects 

 as protective forests, the use of trees in pre- 

 serving water supply, the management of 

 woodlands, etc., are fully illustrated. Many 

 photographs and maps will be shown.
