However, it may be questioned whether the statistical data tell the whole 

 story. While statistics show almost no influence of the supply and price 

 of oranges on the price of apples, it is true that the per capita consumption 

 of apples is declining. Apparentlj', also, the type of demand is changing, 

 and apples are being used for different purposes since the orange has be- 

 come so largely the fruit on our breakfast tables. 



The price variations of Baldwin apples in Boston are chiefly determined 

 by three factors not related to other fruits: the size of the United States 

 apple crop, the size of the New England crop, and the general level of 

 prices. Of these the size of the United States crop is the most important 

 factor. 



The price of Mcintosh apples is, however, little influenced by the total 

 volume of apples on the market or by New England production, but is 

 markedly affected by the general level and trend of prices. Correlations 

 of supply and price of various other fruits with the price of Mcintosh 

 indicate that no one of these has any noticeable influence. 



Part-Time Farming. (David Roznian) The project on part-time farm- 

 ing has been completed and the material published as Bulletin 266. 



Recreational and Forestry Uses of Land. (David Rozman). Data on 

 land values, taxation, and area held by non-residents were secured from 

 the assessors' books in 71 towns, representing 2.5 per cent of all towns 

 in the State with a population of less than 10,000. This material is now 

 being tabulated and analyzed as to its bearing on the problems of land 

 utilization. 



Detailed information on land utilization was obtained in several towns 

 through personal interviews with assessors, town clerks, real-estate men, 

 and other local people. No definite conclusions from this study will be 

 available until completion of the field work during the next spring. 



Factors Affecting Egg Prices. (A. H. Lindsey). Wholesale price quota- 

 tions on the Boston market were used for the basic material of this study. 

 I,ack of purchasing power in 1929 and 1930 caused the trend of egg prices, 

 which was already downward, to turn even more sharply downward. The 

 improvement in quality of western eggs has not seriously affected the 

 favorable differential which has existed between prices of western and 

 nearby eggs. 



A formula for forecasting peak prices of eggs in November from data 

 on June first has been worked out with an accuracy in results of within 

 two cents, two years out of three. The average price of eggs in April may 

 also be forecast from October — December data with an accuracy of within 

 2.8 cents in two-thirds of the cases. 



The Relation of Quality Factors to Price of Eggs. (A. H. Lindsey). 

 Quality factors used were air cell, weight, condition of yolk, condition of 

 white. Prices were found by purchase of eggs from retail stores in Boston. 

 Three periods were studied — April, August, and November. Weight was 

 of much greater significance in April than in November. Air space was 

 most important in November. Condition of yolk was most important in 

 April. The combined effect of all quality factors on price was of greatest 

 importance in August. 



Competitive Factors Influencing the Supply of Market Milk and Cream. 

 (A. H. Lindsey). A study of the Worcester milk shed was made from
