DEPARTMENT REPORTS. 117 



resignation of Mrs. Zae Northrup Wyant, at the close of the fiscal year. I 

 shall take occasion to speak of her work in my report to the Director of the 

 Experiment Station. When I took charge of the laboratory in 1912 she was 

 engaged in research exclusively. Since then she has been under the necessity 

 of teaching many classes under many circumstances. Without fail she has 

 measured up to the responsibilities and with ability, energy and rare good 

 nature she has proved what had already been dem.onstrated in the field of 

 investigation, that in the students' laboratory she could command the respect 

 of and stimulate and inspire all. Her capacity for work and versatility hi a 

 setting of rare good humor is without equal in my experience. She leaves a 

 lasting impress on this institution and on the science of bacteriology. 



I wish to thank you for your broad minded, generous and helpful coopera- 

 tion throughout the year. 



Respectfully, 



WARD GILTNER, 

 Professor of Bacteriolog}^ and Hygiene. 

 East Lansing, INIichigan, June 30, 1921. 



REPORT OF THE DEPARTMENT OF BOTANY. 



President F. S. Kedzie, 

 East Lansing, Mich. 



Dear Sir: 



I have the honor to present to you the following report for the Department 

 of Botany for the year closing June 30, 1921. 



The departmental staff remained the same as for the preceding year with 

 two minor changes as follows : 



W. D. ]\Iills was appointed to fill the half-time graduate assistantship which 

 it had not been possible to fill the preceding year, and Miss Bertha A. Hol- 

 lister, seed analyst, was appointed instructor for part time. 



Although there was a marked increase in the number of students taking 

 botany, as regards both required and elective courses, yet the number of both 

 fall far short of that of previous years. 



Of the four graduate students majoring in botany, two completed this 

 work and received the degree of Master of Science A\ath theses as follows: 



Leo Joseph Klotz, A Study of the Celery Early Blight Fungus, Cercospora 

 apii Fres. 



Lionel Earl Tisdale, Bacterial Soft Rot of Lettuce. 



In cooperation with the Michigan Geological and Biological Survey the 

 study of the flora of the Upper Peninsula was continued, in particular that of 

 Gogebic county, and of a portion of Baraga county. The results of the work 

 in the summ.er of 1919 were published in the twenty-second report of the 

 Michigan Academy of Science by Assistant Professor H. T. Darling-ton, under 

 the title "Contril^utions to the Flora of Gogebic County, Michigan". 



Li continuation of the work of over six j^ears on what is eventually to be 

 published as a "Flora of Michigan", Professor Darlington has been working 

 oyer the large family of grasses as they occur in the State, while Miss Thomp- 

 son has been working on the violets of the State. These papers have not yet 

 appeared in print.
