242 THE FISCAL PROBLEM IN MISSOURI Since the pupil-days apportionment is in the nature of a residual, the total available from year to year varies con- siderably. For example, in 1929 the total distributed on this basis was more than three times as great as in 1927, and the amount distributed in 1928 was more than twice as large as in 1927. On the other hand, the teachers’ quota apportion- ment showed a steady increase throughout the period, reach- ing a maximum of almost $1.8 million in 1929. Of the distributions for specific projects, aid to consolidated districts accounted for the largest amount in all years after 1925, and aid to rural schools ranked second in all years except in 1925, when it ranked first. In both 1928 and 1929 aid to consolidated districts accounted for almost one half of the total distributed for specific projects, while in 1925 this form of distribution accounted for only a little more than one seventh of the total. In two of the five years for which data are shown the amount distributed to consolidated districts exceeded the disbursements under the pupil-days appor- tionment. Table 78 shows the sources of revenue that contributed to the state school moneys fund. The data in this table are for the school years ended in the years as indicated, and the receipts from the specific sources cannot be reconciled with the data in other parts of this study, which are on a state fiscal year basis. Also, the considerable difference between the general property tax receipts as shown in this table and in Table 31 is accounted for by the fact that a large part of the receipts from the state general property tax are not credited to the general revenue fund. The most important state tax that benefits the state school moneys is the income tax, which in all years accounted for a larger part of the receipts into the general revenue fund than any other tax. The inheritance tax ranked second in importance in 1929 and was followed by the general property tax, the corporation franchise tax, and the county foreign insurance tax, in the order stated. Since one half of the receipts from the county foreign insurance tax is credited to a special fund which is distributed to the counties for school purposes, and one third of the remainder benefits the state school moneys, it follows that two thirds of the receipts from this source are distributed for school pur-
