228 THE FISCAL PROBLEM IN MISSOURI available for a period of years, as in the case of the study in Boone County. There is a sound reason why one might expect to find that the larger farms would be relatively overassessed in a period of declining land values, particularly when, as in Missouri, the land and buildings are jointly assessed. The relatively higher proportion of value attributable to farm buildings in the case of many small farms is likely to result in discrepancies in assessments, if adjustments in farm values are made on the basis of declining land values as the sole or principal factor. The tendency on the part of the assessor will be to decrease the value of all farm properties in about the same proportion, whereas the value of the large farms has really been affected to a greater extent than that of the small farms. If, as seems probable, the general property tax is to remain for some time to come the principal source of local revenue, it is highly desirable that assessments of farm properties should be placed upon as uniform a basis as possible. Va- riations among the several counties and within the same county or smaller governmental division should be reduced to a minimum. Probably the only way in which this result can be accomplished is by means of a system of effective central supervision of assessments, as outlined in Chapter VI. The taxes paid by farmers should be levied on uniform valuations, and, as soon as assessments are placed on a fairly uniform basis throughout the state as a whole and therefore within the various counties and smaller govern- mental divisions, the burden of farm taxes will be distributed more equitably. The Taxation of Farm Mortgages Farm mortgages in Missouri are taxable to the mortgagee at general property tax rates. In assessing farm property that is mortgaged, no allowance is made on account of the mortgage. The result is that the combined assessment of a farm and the mortgage on it may be greatly in excess of the assessment for a similar farm on which there is no mortgage indebtedness. Consequently, it is contended that the farmer operating a mortgaged farm is discriminated against as com- pared with the farmer who owns his property outright. The
