Feb., 1927] PROGRESS OF AGRICULTURAL EXPERIMENTS 37 



organized into a cost route study by H. C. Woodworth, G. F. Potter, 

 and H. A. Rollins. Financial and daily labor records worked out by 

 the Bureau of Economics for cost route studies elsewhere, are being 

 kept on the farms. 



At the end of the fiscal year this project had been under way only 

 about two months. The farmers were keeping the records up to date. 

 Some difficulty was experienced at first in getting definite details as to 

 the kind of woi'k done, but the men now have a better understanding 

 of what is needed and are coo])erating splendidly. 



Commercial Apple Orchard Survey — {Purncll Fimd) 



Work on the aj^iile orchard survey was completed during the year by 

 G. F. Potter and H. A. Rollins, and the results have been published in 

 Bulletin 223. This work indicates that there will be a material in- 

 crease in fruit production in New Hamjishire during the next ten to 

 fifteen years. Definite recommendations (^an be made in view of this 

 situation as to methods of i)roduclion and nuirketing which it is 

 believed should be ado])ted by fruit growers in this section. 



The survey also jioints out a probable 300 per cent increase . in the 

 crop of Mcintosh. This means that problems in relation to handling 

 and storing of this rather tender variety will be acute at an early date. 

 It is hoped that the equipment will soon be available so that investiga- 

 tions on these problems may be started at this station. 



RURAL ELECTRICITY 



Relation of Electricity to Agriculture — [Miscellaneous Income Fund) 



This pi-ojcct, which is carried on in cooperation with the National 

 and State Committees on the Relation of Electricity to Agriculture, is 

 of such imi^ortance that a separate report on the progress of the past 

 year is to be published. Data have been secured regularly during the 

 year by ^^^ T. Ackerman on the seven exiierimental farms selected in 

 the state. They include tests on household ranges, dishwashers, water 

 pumps, hot water heaters, bottle washers, household refrigerators, 

 clothes washers, milking machines, cream separators, milk-cooling 

 water pumjis, dairy refrigerators, battery chargers, silo cutters and 

 blowers, hay fork hoists, fertilizer mixers, ])ortable chore motors, iron- 

 ing machines, yard search lights, fertilizer grinders, poultry lights, 

 drinking fountains and fountain heaters for poultry, electric brooders, 

 grain and feed mixers, grain elevators, violet ray equipment, electric 

 incubators, poultry pen cleaning equipment, apple graders and sorters. 



SOILS 



Soil Fertility Studies — {Purnell Fund) 



Five different types of experiments are being conducted under this 

 main heading by F. S. Prince, and T. G. Phillips. 



1. Effect of Manure, Fertilizers and Lime on Worn-Out Hay Lands 



A portion of the field on the Wlienal farm at Greenland, N. H., 

 leased for experimental purposes in 1925, was plowed, prepared, and
