work in the investigation conducted by us, as then Entomologist of 

 the Department, together with the results of Mr. Trel ease'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 uec- 

 tar glands of the cotton plant. 



In September, 1880, the New Orleans Democrat published a long letter 

 on the Cotton Worm from us, giving some of the later results of the 

 investigation, under the followiug sub-heads: Principles established; 

 The Best Poisons ; London Purple ; Pyrethrtim; Oils; Improved Appli- 

 ances; Poisoning from Beloit ; Early Poisoning; Weather — Conclusion. 



\Ye refer to the bibliography for a number of later newspaper arti- 

 cles, and will only call attention, in conclusion, to the article by J. P. 

 Stelle, in the Mobile Register^ July, 1881, entitled "Killing Cotton 

 Worms," in which the writer discusses Our Native Plants, Pijrethrum^ 

 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. Ifc was published in full in the Atlanta Constitution 

 for November 5, and also in a pamphlet issued by the Departmeut of Ag- 

 riculture, entitled "Address of Hon. Geo. B. Loring, Commissioner of 

 Agriculture, and other Proceedings of 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 discussion of im- 

 proved appliances for its destruction. It was also republished in the 

 Annual Report of the Department of Agriculture for 1881-'82, pp. 152- 

 157. 



During the years 1879, 1880, and 1881, the Galveston Neics, the Selma 

 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.
