The committee on bibhography presented the following resolution

entomology : 
To facilitate the more prompt distribution of information on the literature 
of economic entomology, the Association of Heonomic Entomologists respect- 
fully request the Office of Experiment Stations of the United States Depart- 
ment of Agriculture to enlarge its present bibliographical work in this direc- 
tion, in accordance with the following suggestions: 
(1) That the bibliography now being published by the Office of Experiment 
Stations in the Experiment Station Record be issued also as a separate, and 
that a copy be mailed to each member of the Association. 
(2) That copies of this bibliography be printed on stiff paper in such form 
that they may be cut apart and used as a card catalogue, a copy of this style 
of issue to be sent to each member of the Association desiring it. 
(8) That the monthly reports be combined at the end of each year, properly 
classified by subjects, and reissued as a special bulletin with full index. This 
yearly bulletin to be published by the Office of Experiment Stations or by the 
Bureau of Entomology, as may be arranged, and to be in effect a continuation 
and supplement of the Bibliography of Economic Entomology, published hith- 
erto from time to time by the Bureau of Entomology.

SOME NOTES ON THE FUMIGATION OF HOUSEHOLD INSECTS AND 
THEIR EGGS WITH HYDROCYANIC-ACID GAS. 
By J. L. Puinuies, Blacksburg, Va. 
Some buildings used as living apartments near Blacksburg were 
Jound in the early summer of 1904 to be plentifully supphed with 
Clinocoris lectularia Linn. in all stages of development. It was 
finally decided to fumigate one of these buildings with hydrocyanic- 
acid gas. The building is a four-story brick and contains approxt- 
mately 150,000 cubic feet of air space distributed in eight sections. 
The windows were tightly wedged, and then calked with old cloth 
to prevent as much as possible the escape of the gas. The quantities 
used were 80 avoirdupois pounds of potassium cyanide, 96 pounds of 
sulphuric acid, and 240 pounds of water. The water and acid were 
first put into the jars, of which there were one or more to each section,
