REPORT ON THE BOLL WORM OF COTTON. 
ACKNOWLEDGMENTS. 
My first acknowledgments are due to Dr. 0. V. Eiley and to Mr. L. 
O. Howard, who have furnished valuable aid in the determination of 
specimens ; to Mr. E. A. Schwarz for identifying Coleoptera; to Mr. 
Theo. Pergande for naming ants, and also to Mr. Nathan Banks, who 
was assigned to me in my work at Shreveport, for determining spiders. 
The planters at Shreveport deserve great praise for their uniform 
courtesy, hearty cooperation, and the many sacrifices made in devoting 
time and labor to the promotion of field experiments. Those who as- 
signed portions of their plantations for the sole purpose of testing 
remedial measures, and who therefore deserve personal mention, are 
Messrs. J. H. Fnllilove, Daniel Nicholson, S. J. Ziegler, and John 
Caldwell, all of Shreveport; Mr. M. A. Curtis, of Curtis, La., and Mr. 
John Glassell, jr., of Rush Point, La. 
The wide geographical distribution of the Boll Worm, and the differ- 
ent natural conditions in the various regions where it occurs, made it 
quite impossible to cover the entire ground without the assistance and 
cooperation of intelligent persons throughout those regions. Accord- 
ingly arrangements were made with the several State weather services 
to have their observers give special attention to any facts of interest 
and value to the investigation. This was accomplished through the 
efforts of the directors of the several services. Mr. M. G. Wright, jr., 
of Shreveport, La.; Prof. K. B. Fulton, University, Miss.; Mr. F. II. 
Clark, Little Rock, Ark.; Dr. J. M. Cliue, Galveston, Tex.; Mr. George 
E. Hunt, Xew Orleans, La., and Prof. P. H. Mell, Auburn, Ala., merit 
special mention for their many favors. 
While on a trip through northern Texas for the purpose of making 
special observations, much depended upon the assistance of observers 
in that section. It is a source of much satisfaction to state that no de- 
lay was experienced at any point, and that the work was facilitated in 
every way possible. At Mesquite, Tex., Messrs. S. G. Lackey ami T. 
P. Worthington gave valuable information concerning their localities,
