Gloucester Ferry Company _v._ Pennsylvania,[619] stated flatly that "Commerce among the States * * * includes the transportation of persons,"[620] and hence was not taxable by the States, a proposition which is still good law.[621] Four years earlier it had been held that the transmission of telegraph messages from one State to another, being interstate commerce, was something that the State of origin could not tax.[622] State Taxation of the Interstate Commerce Privilege: Foreign Corporations DOCTRINAL HISTORY In the famous case of Paul _v._ Virginia,[623] decided in 1869, it was held that a corporation chartered by one State could enter other States only with their assent, which might "be granted upon such terms and conditions as those States may think proper to impose";[624] but along with this holding went the statement that "the power conferred upon Congress to regulate commerce includes as well commerce carried on by corporations as commerce carried on by individuals."[625] And in the State Freight Tax Case it is implied that no State can regulate or restrict the right of a "foreign" corporation--one chartered by another State--to carry on interstate commerce within its borders,[626] an implication which soon became explicit. In Leloup _v._ Port of Mobile,[627] decided in 1888, the Court had before it a license tax on a telegraph company which was engaged in both domestic and interstate business. The general nature of the exaction did not suffice to save it. Said the Court: "The question is squarely presented to us, * * *, whether a State, as a condition of doing business within its jurisdiction, may exact a license tax from a telegraph company, a large part of whose business is the transmission of messages from one State to another and between the United States and foreign countries, and which is invested with the powers and privileges conferred by the act of Congress passed July 24, 1866, and other acts incorporated in Title LXV of the Revised Statutes? Can a State prohibit such a company from doing such a business within its jurisdiction, unless it will pay a tax and procure a license for the privilege? If it can, it can exclude such companies, and prohibit the transaction of such business altogether. We are not prepared to say that this can be done."[628]
