BLIGHT-INFECTED CHESTNUT AS 

 DURABLE AS SOUND CHESTNUT 



Service records collected by the United 

 States Forest Service indicate that chest- 

 nut posts, poles, and ties cut from blight- 

 infected trees are as durable in service 

 as similar timber cut from healthy trees. 

 Inspections on posts in one locality during 

 eight years of service showed that decay 

 progresses about as rapidly in undiseased 

 posts as in blight-infected posts. 



The blight fungus attacks living trees 

 and grows in the hark, particularly in the 

 cambium layer, but it does not penetrate 

 deeply into the wood itself. The blight 

 finally kills the tree, effectively girdling it 

 by separating the bark from the wood. 



Blight-killed chestnut should be cut and 

 utilized as soon as possible. Allowing 

 dead trees to check and become infected 

 with decay in the woods shortens the 

 service life of timbers cut from the tree. 



A "LITTLE SISTER" TO CRATER 

 LAKE 



"In the July issue, of American Forestry, 

 under a pretty picture of a little section 

 of Crater Lake, Oregon," writes Mr. J. E. 

 Pemberton, of San Francisco, "I find the 

 following: 'There are crater lakes in other 

 lands, but the one lake of its kind in the 

 United States exceeds all others in beauty 

 and magnificence of setting.' 



"Now I do not wish to depreciate in the 

 least Crater Lake for 'beauty and magnifi- 

 cence of setting.' Maybe the Creator could 

 make something more beautiful and give it a 

 more beautiful setting if He wished; but I 

 have no reason to suspect that He ever 

 did ; and know no reason why He should. 

 But there is another crater lake in this big, 

 beautiful country of ours ; and, in the eyes 

 of many, it is quite the equal of Crater 

 Lake, Oregon. 



"It is known as Crystal Lake, and is 

 near Quincy, in Plumas County, California. 

 It is of much smaller size than Crater Lake

but, otherwise, is almost a duplicate of it ; 

 has a strikingly similar 'setting' and I 

 cannot recall any feature of either lake or 

 its surroundings which could make it more 

 beautiful, splendid or magnificent than the 

 other. .And adjectives are all too weak to 

 describe either. Crater Lake is more gi- 

 gantic, but that is the only advantage it has 

 over Crystal Lake, and the advantage of 

 mere size is a matter of opinion only. 

 The fact that Crater Lake is so well known 

 and its Uttle sister crater lake, called 

 Crystal Lake, so little known^ well illus- 

 trates the maxim 'It pays to advertise.' " 



KILN DRYING DOUGLAS FIR 



A study of the kiln drying of Douglas 

 fir common lumber has been begun in the 

 Northwest by Albert Hermann, expert 

 from the Forest Products Laboratory of 

 the Forest Service. This work is being 

 carried on under a cooperative agreement 

 between the Forest Service and the West 

 Coast Lumbermen's .Association. Up to 

 the present time lumbermen of this re- 

 gion have found it impossible to kiln dry 

 common grades of Douglas fir lumber. 

 The object of the study is to develop 

 suitable drying methods for diflferent 

 thicknesses of Douglas fir common and 

 to determine the loss in grade in drying 

 which may be expected by these methods.
