4rt EXPERBIEXT STATION. [Jan. 



excellent work done in the eastern part of the State, in co- 

 operation with the Xashoba Fruit Growers' Association and 

 several of the county farm bureaus, that the apple scab, a 

 disease which caused very serious financial loss in 1920, can be 

 controlled. The bringing together in bulletin form of available 

 information on the composition, nature and properties of in- 

 secticides and fungicides, through the Departments of Chemis- 

 try, Entomology and Botany, is a service to fruit growers and 

 general farmers for which they seem to be most appreciative. 

 The work done in the Department of Plant and Animal 

 Chemistry in studying the possibility of successful preservation 

 of apple pomace promises to bring into general use a home- 

 produced by-product of manufacturing which has heretofore 

 been largely wasted. The work done in the same department 

 and in the Department of Agriculture, extending back for a 

 period of years, on the effectiveness of ammonium sulfate is 

 also very timely, in view of the greatly increased national pro- 

 duction of this commodity. Space will not permit of more 

 detailed illustrations. 



Changes in Staff. 



There have been six resignations during the year; one partial 

 transfer of a station worker to the teaching department of the 

 institution; one staff officer retired through the automatic 

 provisions of the retirement law; and four appointments to 

 new positions. In detail these changes are as follows : — 



Miss Anne C. Messer, investigator in chemistry, resigned 

 Jan. 31, 1921, on account of ill health, after a little more than 

 a year of efficient service. The position has been filled by the 

 appointment of Mr. Charles 0. Dunbar, a recent graduate of 

 the College. 



Miss Rebecca L. Mellor, clerk in the Department of Plant 

 and Animal Chemistry, resigned July 13, 1921. ]\Iiss Mellor 

 had given very satisfactory service for a period of seven and 

 one-half years. Miss JMargaret Eppler has been appointed in 

 her place. 



Miss Marguerite G. Ickis, curator in botany, resigned her 

 position July 31, 1921. Among other items of service to the 

 station and institution particularly noteworthy is the excellence 

 of her photographic work on difficult subjects. This work has
