few visits to retail establishments will be needed to convince one that 
most salesmen appear misinformed, amd are claiming no difference in 
effectiveness between the genuine and the chests lined with a cedar 
veneer. Frank Rabak, of the Bureau of Plant Industry, states that his 
analyses show that there is about 15 times as much cedar Qil,in the 
square foot of three-quarters inch cedar heartwood as there is in. the 
same area of cedar veneer one-twentieth of an inch thick, and that the 
oil evaporates much faster from veneer than from the thicker lumber. 
On the invitation of H. C. Cole, Secretary, Dr. Back attended 
the convention of the Insecticide and-Disinfectant Manufacturers Asso- 
ciation, held in the hotel Astor in New York City on December 14. Of 
special interest to entomologists was a motion picture exhibited by the 
Chemical Warfare Service depicting the warfare against insects. 
The December issue of the "Furniture Manufacturer" contains an 
article, "Tobacco beetle as a pest of furniture," by Back and Cotton. 
One thousand reprints have been presented to the Bureau for use in cor- 
respondence. W. V. Morrow, editor of the Furniture Manufacturer, in 
writing Secretary Jardine on December 21, says, among other things, 
"The work Dr. Back and Dr. Cotton are engaged in is of great commercial 
importance to the furniture industry. It is rather odd to think of the 
Department of Agriculture being of such direct assistance in the manu- 
facturing problem, but I know of no problem in the furniture industry now 
that is of greater importance than that of overcoming the insects."
