According to the census, the true valuation of real and personal property in the United States in 1890 was $65,037,091,197, of which real estate with improvements thereon made up $39,544,544,333. Of course, from the latter must be deducted, in applying these sections, all unproductive property and all property whose net yield does not exceed $4,000; but, even with such deductions, it is evident that the income from realty formed a vital part of the scheme for taxation embodied therein. If that be stricken out, and also the income from all invested personal property, bonds, stocks, investments of all kinds, it is obvious that by far the largest part of the anticipated revenue would be eliminated, and this would leave the burden of the tax to be borne by professions, trades, employments, or vocations; and in that way what was intended as a tax on capital would remain, in substance, a tax on occupations and labor. We cannot believe that such was the intention of congress. We do not mean to say that an act laying by apportionment a direct tax on all real estate and personal property, or the income thereof, might not also lay excise taxes on business, privileges, employments, and vocations. But this is not such an act, and the scheme must be considered as a whole.
