REPORT OF THE DEPARTMENT OF BOTANY. 



A. VINCENT OSMUN. 



The work of the Department of Botany during the last year 

 has not deviated in any important respect from that previously 

 reported. Research work, the normal function of the Experi- 

 ment Station, continued to engage the major attention of the 

 staff. While no new projects were started, certain changes and 

 additions were made in some of those under way. 



Report on Project Work. 



The report on project work is one of progress. Some lines 

 of investigation are essentially completed. Several bulletins 

 and technical papers are in course of preparation by members 

 of the staff, and will be presented for publication as speedily as 

 other work will permit. 



Tobacco Investigations. — Tobacco investigations, under the 

 leadership of Dr. G. H. Chapman, have so developed that it 

 has become advisable to discontinue the plots located on 

 privately owned farms during the last four years. The project 

 has been reorganized, and in the future plots will be conducted 

 on College-owned land controlled by the Station. A progress 

 report on the project was published in March of the present 

 year as Bulletin No. 195. 



Investigation of Onion Diseases. — Investigation of onion smut 

 under the project on onion diseases has continued, with results 

 on the field plots confirmatory of those previously obtained. A 

 large amount of painstaking work on the morphology and life 

 history of the onion smut fungus, Urocystis cepuloF, has been 

 carried on by Dr. P. J. Anderson, who expects to publish a 

 technical paper on these phases of the investigation during the 

 next vear.
