LETTER OF TRANSMITTAL. 
U.S. DEPARTMENT OF AGRICULTURE, 
Bureau or ENTOMOLOGY, 
Washington, D. C., October 8, 1911. 
Str: I have the honor to transmit herewith for publication a paper 
dealing with the Dying of Pine in the Southern States—Cause, 
Extent, and Remedy. It censists of a series of revised circular 
letters which have been used during the present year in an active 
campaign by this bureau through a forest-insect field station located 
at Spartanburg, S. C., the purpose of which has been to study the 
character and extent of the dying pine and to give instructions and 
demonstrations to the owners within the worst affected areas on the 
most economical and effectual means of control. 
The known destructive habits of the southern pine beetle, which 
is the cause of the trouble, and the threatening character of the pres- 
ent outbreak render its immediate control of the greatest importance 
to the people of the South Atlantic and Gulf States. It is perfectly 
capable of killing a large percentage of the young and matured trees 
of the pine forests of the entire South, as it did in West Virginia and 
Virginia in 1890 to 1893. 
The paper gives the essential facts relating to the insect, its work, 
practical methods of control, and how to protect the pine from its 
depredations in the future. 
It is absolutely necessary that the owners of farmers’ woodlots, as 
well as the individual and organized owners of large areas of growing 
and matured pine, should be familiar with the essential requirements 
of locating and disposing of the infested timber in order to meet with 
success in any effort to control it. Therefore, I recommend the pub- 
lication of this paper as a Farmers’ Bulletin. 
Respectfully, L. O. Howarp, 
Entomologist and Chief of Bureau. 
Hon. JAMEs WILSON, 
Secretary of Agriculture.
