REPORT ON PROJECTS. 



Projects Completed. 



During the year ten projects were completed, as follows: 



Agriculture 1. Comparison of nitrogenous fertilizers. Assistant Professor Gaskill. 



Animal Husbandry 2. Survey of garbage feeding plants in Massachusetts. As- 

 sistant Professor Glatfelter. 



Botany 10. Apple disease control investigations. Assistant Professor Doran. 



Chemistry 2. Digestion experiments. Professor Lindsey and Assistant Professor 

 Archibald. 



Chemistry 5. Chemistry of arsenical insecticides. Professor Holland and Mr. 

 Dunbar. 



Chemistry 6. Lime absorption and acidity of Field A. Professor Morse. 



Chemistry 7. Effects of sulfate and muriate of potash on the soil of Field B. 

 Professor Morse. 



Chemistr\^ 12. Attempting to improve the nutritive value of grain hulls. Pro- 

 fessor Lindsey and Assistant Professor Archibald. 



Chemistry IS. To determine the mineral constituents of forage crops. Profes- 

 sor Lindsey and Assistant Professor Archibald. 



FertiUzer Control 1. Vegetation tests to study nitrogen availability. H. D. Ras- 

 kins, Official Chemist. 



In most of the above cases final report has been made, although publication 

 may be delayed until other related work is completed. 



Projects Transferred to the Inactive List. 



Owing to the inability of the Station to give adequate financial support, the 

 following projects have been transferred to the inactive list: 



Botany 5. Study of plant stimulation by formaldehyde. 

 Chemistry 3. Summer forage crops. 

 Entomology 2. Economic importance of digger wasps. 

 Entomology 3. Control of the onion maggot. 

 Microbiology^ 1. Microbiological investigations in milk. 

 Microbiology 3. Canning investigations. 



Projects Discontinued. 



The Station policy of submitting every project of record to critical analysis of a 

 committee has resulted in certain projects being discontinued, because of unsatis- 

 factory operating conditions. Variation in the soil, inability to secure adequate 

 machinery, lack of personnel — any one of these may be a contributing cause. 

 Based upon recommendations of committees, the following projects have been 

 discontinued : 



Agriculture 4. Methods of applying lime and quantity of application. 



Agriculture 6. Top-dressing permanent grasslands. 



Agriculture 8. Determination of effect of fertilizer on the germination of onion seed. 



Botany 12. Potato spraying versus dusting in the control of late blight. 



Market Garden Field Station 4. Variet}^ and strain tests of tomatoes. 



Market Garden Field Station 5. Growth control by means of intercropping. 



Catalog of Active Projects, December 1, 1923. 



Plant Nutrition and Soil Fertility. 

 Chemical Investigations. 

 Chemistry 14. A study of the availability of soil potash, with the object of 

 developing a system of diagnosis for soils of the State. Professor Morse. 



Microbiological Investigations. 

 Microbiology 2. Soil fertility as influenced by micro-organisms in their relation 

 to the presence and disappearance of organic matter. Assistant Professor Itano 

 and Mr. Sanborn.
