This paper was republished in 1894 under the same title 

 and with only slight changes in the Third Annual Report of the 

 Kentucky Agric. Kxp. Sta. of the State College of Kentucky 

 for the year 1890. pp. 43-46. Frankfort, Ky., 1894. 



1893. PAMMEL, L. H. Preliminary notes on a ruta- 



baga and turnip rot. Bot. Gazette, Jan., 1893, 



P. 27- 



Abstract of a paper read before the Am. Asso. of Agric. 

 Colleges and Exp. Stations; New Orleans meeting. This is 

 the bacterial disease subsequently described more fully by 

 Professor Pammel in 1895.

(Bacillus campeslris n. sp.) Iowa Agr. College, 

 Exp. Sta. Bull. No. 27, Ames, Iowa, 1895, pp.

This paper was reprinted in Am. Monthly Microscopical 

 Journal for May. 1 895 , p. 1 45 .

Am. Asso. Adv. Sci., 1895, vol. XLIV, p. 193 

 (Springfield Meeting), Salem, May, 1896. 



Said subsequently to have been based on a study of the 

 black-rot, but this fact can not be determined from the abstract 

 which is all that was ever published. Infections with pure 

 cultures had not been obtained. 



1897. SMITH, ERWIN F. A bacterial disease of Crucif- 



erous plants. Science, N. S., June 18, 1897, 

 vol. v, p. 963, 



Abstract of a paper read before the Biological Society of 

 Washington in May, 1897. 



1897. SMITH, ERWIN F. Pseudomonas campestris 

 (Pammel), the cause of a brown-rot in crucif- 

 erous plants. Centralbl. f. Bakt. etc., 1897, 

 2te. Abt., Bd. Ill, No. 11-12, July 7, pp. 284- 

 291; No. 15-16, Aug. 18, pp. 408-415; No. 

 17-18, Sept. 10, pp. 478-486, i colored plate 

 (showing signs and the character of the bac- 

 terial growth on potato). 



This paper gives at length the reasons for the statements 

 previously made in Science, and adds some new facts, the most 

 important of which perhaps is that infections of the uninjured 

 plant can take place by way of the water-pores. 



1897. SMITH, ERWIN F. The spread of plant diseases : 

 A consideration of some of the ways in which 

 parasitic organisms are disseminated. A 

 lecture delivered before the Mass. Hort. Soc., 

 March 27, 1897. Proc. of the Society for 

 1897. Boston, 1898. Also a separate. 



An abstract appeared in one of the Boston papers soon after 

 the lecture, and there was also a separate of this abstract. 



1897. STEWART, F. C. The stem-rot of cabbage. 



Vicks Illustrated Monthly Magazine, July, 

 1897, vol. xx, No. 9, new series, p. 141. 



An editorial which includes, however, a letter from Mr. 

 Stewart who says: "On Long Island there is a bacterial stem- 

 rot of seed cabbage which is very destructive in some seasons." 

 The distribution of the disease is attributed to infected seeds.

 of the Society for Plant Morphology and Physiology, Dec. 28, 

 1897.

Three diseases are discussed : Wilt of the Cucumber; Brown 

 rot of the Potato; and Black-rot of the Cabbage.

Mostly polemical but one additional fact is announced, viz., 

 that the ability of Pseudomonas campestris to liquefy gelatin 

 depends on how the gelatin is made, and thus the apparent 

 contradiction, in this particular, between Pammel's results and 

 those of the writer is explained.

This paper was not read at the Convention (see p. 86) and 

 the MS. remained in the hands of the author for revision until 

 Oct. 27, 1897. The Proceedings of which this forms a part, 

 bears no date of issue but it was received from the binders and 

 distributed by the U. S. Dept. of Agric.. March 28, 1898. A 

 brief synopsis of this paper appeared in the Exp. Sta. Record, 

 1897-98, vol. ix, p. 319.

This paper was sent to the printer the first of March, 1 898, 

 i. e., one year after the sending away of the Centralblatt paper 

 of 1897 and after all of the leading statements in the latter 

 paper had been experimentally re-examined by the writer and 

 confirmed. The halftone from a photograph of part of a leaf 

 (enlarged 2$ times and made by transmitted light) probably 

 gives as good an illustration of the foliar symptoms as can be 

 obtained in black and white by use of photography.
