the fundamental scientific departments. Seemingly the only 

 way in which effective co-operation can be brought about lies 

 in securing the necessary co-ordinated study. 



This work of project organization is not yet completed. The 

 following, however, shows the projects either now under way, 

 or so organized as to be under way in the very near future: — 



Plant Nutrition — Comparative Fertilizer and Lime Tests. 



Comparison of nitrogenous fertilizers; comparison of sulfate and 

 muriate of potash; comparison of potash carriers; comparison of 

 phosphate carriers; effects of plant foods alone and in combina- 

 tion; use of chemicals in supplementing stable manure for garden 

 crops; orchard fertilization; experiments with Barium-Phosphate; 

 relative value of different sources of lime; high potash versus high 

 phosphoric acid fertilizers; study of bacterized peat; manure 

 economy tests. 

 Plant Nutrition — Chemical and Biological Investigations. 



Chemical effects of muriate and sulfate of potash; lime absorption 

 and acidity of Field A; soil fertility as influenced by micro- 

 organisms. 

 Plant Adaptation — Variety Tests. 



Variety tests of fruits; asparagus variety test; limited variety test 

 of vegetables; observations of summer forage crops. 

 Plant Physiology and Heredity. 



Study of optimum conditions of light for plant response; the inter- 

 relation of stock and scion in apples; the genetic composition of 

 peaches; study of tree characters of fruit varieties; study of the 

 life processes of the strawberry. 

 Cultural Studies. 



Cranberry bog management; cranberry bog weeds; blueberry 

 culture; experiments in pruning apples; study of production \vith 

 greenhouse lettuce and cucumbers. 

 Plant Protection — Insects. 



Studies of insect outbreaks in various localities; limits of insect pests 

 in Massachusetts; the number of broods of the codling moth in a 

 year; dates of hatching of scale insects, and fixing dates for spray- 

 ing such insects; insects affecting the cranberrj'; control of the 

 onion maggot; control of the sciuash-vine borer; burning of foliage 

 by insecticides; control of the scjuash bug; insect control on market- 

 garden crops; study of the chemistry of arsenical insecticides. 

 Plant Protection — Fungous Troubles. 



Investigation of onion diseases; experimental spraying for control of 

 cucumber mildew under glass; methods for controlling lettuce 

 drop; fungous diseases of cranberries (co-operative with the 

 Bureau of Plant Industry, United States Department of Agri- 

 culture) .
