that are, or well may be, grown in New Hampshire with reasonable 

 expectation of profit; to determine to what extent the present farm 

 production is meeting that demand ; and to study the factors involved in 

 the readjustment of the production of certain commodities, and better 

 land utilization. 



A study of the railroad receipts and shipments of hay, potatoes, fruit, 

 most of the vegetables, and poultry and dairy products is being made and 

 is supplemented by estimates from retailers as to the quantity of products 

 handled. An analysis of local production of these products is also being 

 made, and we are planning to study the grade, quality, packing, and 

 methods of distribution of locally grown products as compared with those 

 shipped in from other areas. 



2. Apple Marketing Study. The marketing problems of New Hamp- 

 shire are, of course, inextricably entwined with those of New England as 

 a whole. With this fact in mind we are co-operating with the other New 

 England states through the New England Research Council on Marketing 

 and Food Supply in the first of what it is hoped will be a series of commod- 

 ity studies. The apple industry was selected for this purpose, and a 

 uniform plan of securing data from the commercial orchards of this area 

 has been followed. Personal visits have been made to practically 100 per 

 cent, it is believed, of the commercial orchards of the state, and detailed 

 records have been taken showing the production and plantings by varie- 

 ties, methods of marketing, and other pertinent facts. A report of this 

 investigation will probably be made within the coming year. 



3. Soil Stuchj. The problem of the run-out hay land of the state is 

 another question of fundamental importance to our agriculture. One 

 of the first steps under the Purnell Act has been to establish experiments 

 that will run over a period of years to determine the effect of certain 

 cultural practices and treatments on neglected hay lands, and to study 

 the chemical composition of the soil used. Three mmediate experiments 

 have been decided upon to throw light on this problem: one with grass, 

 one with legumes, and one with rotations. 



One of the difficulties in the past which has prevented successful work 

 along this line has been the lack of any typical soil on the college farm 

 that was either sufficiently worn out or sufficienth'- uniform. For this 

 reason it has been decided to locate these experiments in other parts 

 of the state. After a considerable amount of search for suitable locations, 

 a field has been found in Greenland where there have already been started 

 the grass and legume experiments. 



4. Dairy Nutrition. The long-time studies of nutrition, which are 

 being conducted in connection with the Carnegie Institute of Washington, 

 have dealt principally with steers. The results of this work have been 

 such as to justify its expansion into the more complex problem of the 

 nutrition of dairy cows, particularly since it has been found possible 

 to enlarge our facilities materially without greatly expanding our ' ' over- 

 head charges." The object of the new work will be to study the basal 

 energy metabolism as affected by different planes of nutrition, the effect of 

 environmental temperature, some of the physiological activities in relation 

 to varying feed levels, and other important factors. 



This work will be carried on more or less continuously with two animals 

 subject to laboratory control. As a supplement to it, arrangements have 

 also been made with the Dairy Department for a physiological study of
