DISEASES OF TAXODIUM AND LIBOCEDRUS. 



Mr. A. J. Johnson, and a number of lumber companies in 

 California, Oregon, and Washington. The disease is one 

 which resembles the one in the cypress in its method of 

 growth. The decay begins somewhere in the upper part 

 of a tree and proceeds both up and down, the lens-shaped 

 cavities appearing at first as darker areas in the wood. 

 Older trees are very liable to be diseased. One correspond- 

 ent, from southern Washington, says: " The proportion 

 of trees affected is very large. We might almost say that 

 the trees are generally so affected in this country." From 

 Placer Co., Cal., another correspondent writes : " Probably 

 more than one-half of the trees are affected in a greater 

 or less degree." From intermediate points similar reports 

 have been received. Young trees, i. e., such as are under 

 12 inches in diameter, are not apt to be seriously diseased. 

 Climatic and soil conditions seem to have as little influence 

 on the prevalence of the disease, as they do in the case of 

 pecky cypress. Wherever Ztibocedrus decurrens grows, 

 the defect is also to be found, i. e., from central California 

 northward, as far as it has been possible to learn. The 

 diseased wood is quite durable and can be used for fence 

 posts, scantling, or for wood sills in buildings. The 

 diseased wood is sold for $l-$3 less than sound cedar, 

 per thousand ft. B. M., depending upon the degree 

 of decay. This is an indication that it is at least 

 capable of being used for some purposes. It might 

 bo mentioned here that boards cut from trees of Juni- 

 perus Virginiana affected with a similar disease were 

 recently pulled off a barn where they had been 52 years. 

 The Stimson Mill Co., of Ballard, Wash., writes: "We 

 do not make any difference between sound and rotten 

 cedar; $8 is the price for cedar delivered."
