B,Y GREATLY increasing cash farm income, the war has intensified the need for new series that will reflect changes in special aspects of the financial condition of farmers. From the beginning of the war more than ordinary interest has followed changes in the value of farmers' physical assets like real estate and livestock, and changes in farm debt. It is quite generally recognized that even more pronounced changes may be occurring in farmers' holdings of certain financial assets. During this period of unusually high cash farm income, restricted markets, and enlarged opportunities and obligations to invest in securities of the Federal Government, it is likely that the pattern of the disposition of farm income has been altered considerably and is contributing to the rapid growth of financial assets, like currency, bank deposits, and Government bonds. These financial assets have special significance at this time as they are almost completely liquid and would suffer no depreciation if a recession of prices from wartime levels were to reduce the values of the physical assets. They will, therefore, have an important influence on the ability of farmers to adjust their operations to postwar conditions and they will constitute the farmers' best hedge against a possible deflation. To obtain a somewhat more complete and useful picture of the decided changes which were being wrought by the war in the financial condition of farmers, the Bureau of Agricultural Economics last year undertook to estimate the volume of currency, bank deposits, and Government bonds held by farmers on January 1, 1940 and annually thereafter. This paper is concerned with the Bureau's estimate of the volume of United States savings bonds (Series E) that have been bought by farmers in the United States (Table 1). It is believed that at least 92 per cent of all United States savings bonds purchased by farmers are of this series. Elsewhere these amounts have been presented as the basis of estimates of the value of United States savings bonds held by farmers.' The purposes of this paper are (1) to describe the
