Foreword 



This Bulletin conveys the 67th annual report of the Director 

 of the New Hampshire Agricultural Experiment Station. Contained 

 herein are lists by departments of the nearly 90 formal projects 

 active during the fiscal year ended June 30. 1955. Each project 

 title is accompanied with a number for identification and with the 

 names of the contributing professional staff. Also included in the 

 report are a statement of receipts and expenditures, a summary of 

 State Services, a roster of personnel, and a list of publications. 



On page three of the 66th annual report, Bulletin 418, the 

 Director explained that a new periodical, Progress Report, would 

 replace the reports of progress customarily contained in the annual 

 report. Consequently, this 67th annual report omits this more vo- 

 luminous material, and embodies only the number, title, and per- 

 sonnel for each formal active research project. 



One of the most significant characteristics of the United 

 States economy is the small proportion of our population living on 

 farms, now only about 12 percent, compared with about 40 per- 

 cent at the turn of the century. No other country has experienced 

 such progress. Land in the United States has been plentiful and 

 labor has been scarce, relatively. Agricultural research has provided 

 the know-how for more efficient production, marketing, and process- 

 ing of food and fiber. More know-how combined with technological 

 improvements and mechanization has created in the United States 

 the most effective and efficient commercial farm units for the pro- 

 duction of food the world has ever known. Production per man, 

 not production per acre, has been and is the important thing. 



Interdepartmental cooperation is characteristic of much of 

 the research at this Experiment Station. When a project outline is 

 prepared, and during its activation, members of various depart- 

 ments are called on when the work demands their attention. By 

 this means the project can be sufficiently broad to cover many 

 aspects of the problem. The personnel are aware of the need for 

 efficient research — accomplishment per dollar expended. By this 

 means society is assured of a large return on its investment in 

 agricultural research. 



Many public, private, and industrial organizations have con- 

 tributed to the program of the New Hampshire Agricultural Ex- 

 periment Station. We acknowledge these gifts with gratitude. 



The publications of the Station consist of bulletins, reports, 

 reprints of scientific articles and mimeographs. These may be ob- 

 tained from the Mailing Clerk upon request.
