204 Investigations in Plant Pathology 



on September 1, 1891, Dr. Kellerman resigned his position to 

 accept tiie chair of botany at the Ohio State University. On May 

 1, 1891, Swingle had accepted a call to the Division of Vegetable 

 Pathology of the United States Department of Agriculture. 

 Earlier, when he was informed by Galloway of Swingle's appoint- 

 ment, Smith rejoiced that "Swingle [was] now one of us." A. S. 

 Hitchcock, a graduate of Iowa Agricultural College and an as- 

 sistant in the Missouri School of Botany, took Kellerman's place 

 at Kansas. His interest was more in taxonomy and agrostology 

 than mycology and pathology. However, a very able graduate of 

 the class of 1887, Mark Alfred Carleton, was recalled by his alma 

 mater, Kansas State Agricultural College, from his position as an 

 instructor in natural sciences at Garfield University. His appoint- 

 ment as assistant in botany was to take effect for the year 1892. 

 At this time, Carleton was showing promising astuteness as an 

 investigator of the cereal rusts and smuts, at least, an enthusiastic 

 interest in their study, and, not many years hence, he, too, would 

 be summoned by Gallov/ay to the Department's service. 



Throughout the year 1890, Smith, as he had promised himself 

 to do, did much with photography. In the autumn, he journeyed 

 to Griffin, Georgia, and photographed his inoculated trees, to- 

 gether with the controls, of the experiment. Twice he travelled 

 to Amherst, Massachusetts, discussed with Dr. Goessmann, and 

 Maynard, the results of his orchard experiments in peach yellows, 

 and, while there, became acquainted with James Ellis Humphrey, 

 vegetable physiologist of the Massachusetts Agricultural Experi- 

 ment Station. " Greatly " interested in Humphrey's work on black 

 knot, and knowing him to be a student of Farlow, Smith wrote 

 to Farlow to explain he regretted he had been unable to get to 

 Cambridge also and to praise Humphrey's work. As soon as he 

 returned to Washington, Smith sent Humphrey a specimen of the 

 black knot from Maryland. Harvard's Cryptogamic Laboratory 

 was now in its new building, and Farlow, replying there were a 

 "good many things to be seen," regretted, too, that Smith had not 

 found it possible to visit the Harvard campus. Smith had visited 

 the campus of Yale University, but never Harvard's. Smith 

 informed Farlow concerning the return from studies abroad of 

 Newton B. Pierce,^^ who, before studying plant pathology with
