work in the investigation conducted by us, as then Entomologist of 
the Department, together with the results of Mr. Trelease's observa- 
tions during the summer of 1879. An interesting and unique feature 
of the volume is Mr. Trelease's chapter on Nectar and its Uses, which is 
treated with special reference to the significance of the extra-floral nec- 
tar glands of the cotton plant. 
In September, 1880, the Neic Orleans Democrat published a long letter 
on the Cotton Worm from us, giving some of the later results of the 
investigation, under the following sub-heads: Principles established ; 
The Best Poisons ; London Purple ; Pyrethrum ; Oils; Improved Appli- 
ances; Poisoning from Below; Early Poisoning : Weather — Conclusion. 
We refer to the bibliography for a number of later newspaper arti- 
cles, and will only call attention, in conclusion, to Re article by J. P. 
Btelle, in the Mobile Register, July, 1881, entitled - Killing Cotton 
Worms," in which the writer discusses Our Native Plaits. f\nr> thrum, 
London Purple, Paris Green, Arsenic; and to the lecture delivered by 
us before the Convention of Cotton Planters at the Atlanta Exposition, 
November 4, 1881. It was published in full in tin' Atlanta Constitution 
for November o, and also in a pamphlet issued by the Department of Ag- 
riculture, entitled ''Address of Hon. Geo. li. Luring, Commissioner of 
Agriculture, and other Proceedings <>f the Cotton Convention held in 
Atlanta, Ga., November 2, 1881." The lecture was devoted to a review 
of the natural history of Aletia, but principally to a discn88ion ol 'im- 
proved appliances for its destruction, it was also republished in the 
Annual Report of the Department of Agriculture for L881-$2j pp. L52- 
157. 
During the years 1871), 1880, and 1SS1, the Culrcston X< trs. the Selmtt 
Times, the Mobile Register, and the Atlanta Constitution have all con- 
tained many interesting items and communications upon cotton insects, 
as will appear from the following bibliography, which, While not includ- 
ing all the titles of fugitive articles, will be found to contain all the 
more important references, as we have carefully preserved all such writ- 
ings on the subject during the past decade.
