of property in the State."[558] Again, however, a caveat was entered in behalf of the power of Congress to impose a different rule affording "a temporary exemption" of property transported from one State to another from taxation by the latter.[559] INSPECTION CHARGES Woodruff _v._ Parham and Brown _v._ Houston are still good law for the most part.[560] Nevertheless, there is one respect in which imports from sister States are treated as "imports" in the sense of the Constitution, and that is in being exempt from "unreasonable" inspection charges.[561] It is true, also, that in a series of cases involving sales of oil about 1920 the Court appeared to be contemplating reviving the original package doctrine,[562] but these holdings were presently "qualified" in a sweeping opinion by Chief Justice Taft, reviewing the cases.[563] But taxation is one thing, prohibition another. In the field of the police power, where its applicability was not so much as suggested in Brown _v._ Maryland, the original package doctrine has been frequently invoked by the Court against State legislation, and even today, perhaps retains a spark of life.[564] LOCAL SALES: PEDDLERS By the same token, local sales of goods brought into a State from another State are subject to a nondiscriminatory exercise of its taxing power. Such a tax, the Court has said, "has never been regarded as imposing a direct burden upon interstate commerce and has no greater or different effect upon that commerce than a general property tax to which all those enjoying the protection of the State may be subjected"; and this is true, even of goods immediately to be used in interstate commerce.[565] The commerce clause, therefore, does not prohibit a State from imposing special license taxes on merchants using profit sharing coupons and trading stamps although the coupons may have been inserted in retail packages by the manufacturer or shipper outside the State and are redeemable outside the State, either by such manufacturer or shipper, or by some other agency outside the State;[566] nor yet a nondiscriminatory tax upon local peddling of goods and sales thereof by peddlers even though the goods are foreign or interstate imports, since the sale occurs after foreign or interstate commerce thereof has ended.[567] And in Kehrer _v._ Stewart[568] it was held that a State tax upon resident managing agents of nonresident meatpacking houses did not conflict with the commerce clause, regardless of the fact that the greater portion of the business was interstate in character, the tax having been construed by the highest court of the State as applying only to the business of selling to local customers from the stock of "original packages" shipped into the State without a previous sale or contract to sell, and kept and held for sale in the ordinary course of trade. Contrariwise, a tax on sales discriminatory in its incidence against merchandise because of its origin in another State is _ipso
