4 N. H. Agric. Experiment Station [Bui. 270 



The economic research with fruit has pointed to the necessity for 

 an intensive study of spray management practices and their effect on 

 the crop; such studies were begun on 50 commercial fruit farms 

 during the year. 



The question of land utilization has been of increasing concern in 

 the state during recent years, bound up as it is with the changes in 

 commodity production, urban-rural shifts in population, maintenance 

 of highways and schools, and the possible options for use of farm 

 labor. Preliminary studies in town mapping were followed up this 

 5'ear with a more comprehensive program of investigation in this field. 



Other new projects deal with the marketing problems of Laconia 

 milk and with an extension of the metabolism studies in animal nutri- 

 tion to other animals, viz., the horse, goat and pig. 



The work in rural electricity has been broadened during the year 

 to cover the field of agricultural engineering. 



There have been few changes in staff. The appointment of Prof. 

 M. Gale Eastman as associate dean of the agricultural college has 

 made it advisable to employ an assistant economist in the person of 

 H. C. Grinnell, formerly with the Vermont Agricultural Experiment 

 Station. W. W. Shirley, librarian, resigned during the year, and M. 

 A. Miller of New York has taken his place. Other resignations were 

 those of R. B. Dearborn, and Neil Stuart, assistants in horticulture; 

 Clarence Winchester, graduate assistant in animal husbandry; and S. 

 J. Fisher, graduate assistant in chemistry. L. R. Bryant has been ap- 

 pointed graduate assistant in horticulture, and H. A. Davis, in agri- 

 cultural and biological chemistry; H. N. Colby has been appointed 

 assistant in agricultural engineering.
