The result of the Hylton case was not challenged until after the Civil War. A number of the taxes imposed to meet the demands of that war were assailed during the postwar period as direct taxes, but without result. The Court sustained successively as "excises" or "duties," a tax on an insurance company's receipts for premiums and assessments;[1490] a tax on the circulating notes of State banks,[1491] an inheritance tax on real estate,[1492] and finally a general tax on incomes.[1493] In the last case, the Court took pains to state that it regarded the term "direct taxes" as having acquired a definite and fixed meaning-to-wit, capitation taxes, and taxes on hand.[1494] Then, almost one hundred years after the Hylton case, the famous case of Pollock _v._ Farmers' Loan and Trust Company[1495] arose under the Income Tax Act of 1894.[1496] Undertaking to correct "a century of error" the Court held, by a vote of five-to-four, that a tax on income from property was a direct tax within the meaning of the Constitution and hence void because not apportioned according to the census. Restriction of the Pollock Decision The Pollock decision encouraged taxpayers to challenge the right of Congress to levy by the rule of uniformity numerous taxes which had always been reckoned to be excises. But the Court evinced a strong reluctance to extend the doctrine to such exactions. Purporting to distinguish taxes levied "because of ownership" or "upon property as such" from those laid upon "privileges,"[1497] it sustained as "excises" a tax on sales on business exchanges;[1498] a succession tax which was construed to fall on the recipients of the property transmitted, rather than on the estate of the decedent,[1499] and a tax on manufactured tobacco in the hands of a dealer, after an excise tax had been paid by the manufacturer.[1500] Again, in Thomas _v._ United States,[1501] the validity of a stamp tax on sales of stock certificates was sustained on the basis of a definition of "duties, imposts and excises." These terms, according to the Chief Justice, "were used comprehensively to cover customs and excise duties imposed on importation, consumption, manufacture and sale of certain commodities, privileges, particular business transactions, vocations, occupations and the like."[1502] On the same day it ruled, in Spreckels Sugar Refining Co. _v._ McClain,[1503] that an exaction denominated a special excise tax imposed on the business of refining sugar and measured by the gross receipts thereof, was in truth an excise and hence properly levied by the rule of uniformity. The lesson of Flint _v._ Stone Tracy Co.[1504] is the same. Here what was in form an income tax was sustained as a tax on the privilege of doing business as a corporation, the value of the privilege being measured by the income, including income from investments. Similarly, in Stanton _v._ Baltic Mining Co.[1505] a tax on the annual
