LETTER OF TRANSMITTAL. 
U. S. DEPARTMENT OF AGRICULTURE, 
Division OF ENTOMOLOGY, 
Washington, D. C., June 20, 1894, 
Str: I have the honor to transmit herewith, for publication as a 
Farmers’ Bulletin, a condensed account of the more important insecti- 
cides for farm and garden use, prepared under iny direction by Mr, ©. 
L. Marlatt, first assistant entomologist. Circular No. 1, new series, of 
this division, and Farmers’ Bulletin No. 7 contained information of this 
character, but these documents are out of print and since they were 
published some advance has been made in the matter of insecticides 
which necessitates the publication of some additional matter and some 
change in the methods of preparation of old and standard mixtures. 
The constant call for information of this character will warrant the pub- 
lication of this bulletin in large edition. 
Respectfully, 
L. O. HOWARD, 
Entomologist. 
Hon. J. STERLING MORTON, 
Secretary of Agriculture.
