The Power to Regulate Commerce.—Under the Articles of Confederation, as we have seen, Congress possessed no power to regulate commerce among the states or with foreign nations. That power remained entirely with the states. Each state accordingly made such regulations as it saw fit, without regard to the general welfare. It was this want of commercial power on the part of Congress that contributed as much as anything else perhaps to the downfall of the Confederation. The Constitution as finally adopted gave Congress the exclusive power to regulate commerce among the states, with foreign countries, and with the Indian tribes, which were then treated somewhat as foreign nations for certain purposes. The only limitations placed on the power of Congress in this respect were that no duty should be levied on goods exported from any state; that no preference should be given by any regulation of commerce or revenue to the ports of one state over those of another; and that no vessels bound to or from one state should be obliged to enter, clear, or pay duties in another.
Regulation of Foreign Commerce. In pursuance of the power to regulate commerce with foreign nations Congress has enacted a large amount of legislation relating to tonnage duties, duties on imports, quarantine, immigration, the importation of adulterated foods, wines, teas, and other food products, the conduct of navigation, the construction and inspection of ships carrying passengers, pilotage, clearances, the protection of shipping, the rights of seamen, the registration and insurance of vessels, life-saving appliances, the use of wireless telegraph apparatus, and the like. It was also in pursuance of this power that the Embargo Act was passed in 1807 and the Nonintercourse Act in 1809—both of which were in effect prohibitions rather than regulations of commerce.
The Navigation Laws prescribe with great detail how vessels registered under the American flag shall be constructed and equipped for the comfort and safety of their crews and passengers; how they shall be inspected; rules that shall be observed to avoid collisions, how signals shall be displayed, etc.; the forms of papers vessels must carry; how the wages of seamen shall be paid, the nature of their contracts, etc.
The Tonnage Laws prescribe the rate of tonnage duties that shall be levied on vessels entering American ports. Tonnage duties, as the name indicates, are a form of taxation calculated on the basis of the tonnage admeasurement of the vessel; they are levied on American as well as foreign ships, though the rate is higher on the latter than on the former. Sometimes they have been higher on the vessels of some foreign countries than on those of others, in which case they are known as discriminating tonnage duties. Such discriminating duties are employed for the purpose of favoring the commerce of those nations which extend us commercial privileges and for shutting out or restricting that of nations which discriminate against our trade. In pursuance of the power to regulate foreign commerce, Congress prohibits foreign vessels from engaging in the coasting trade, and permits only citizens of the United States to serve as masters on vessels registered under the American flag. Formerly only American-built vessels could be registered, but in 1914, after the outbreak of the great war in Europe, Congress passed an act allowing ships built in foreign yards, when owned by American citizens, to be registered under the American flag; and more than 100 such vessels have been so registered.
Immigration.—By virtue of the commerce power Congress has enacted a series of immigration laws imposing restrictions on the coming of immigrants to our shores. For a long time immigration from Europe was encouraged rather than restricted, but within recent years so many undesirable persons have found their way to America that Congress has been led to pass various laws designed to shut out the worst of them and admit only the desirable ones.[42]
First of all, the immigration laws exclude convicts, insane persons, paupers and those likely to become paupers, persons suffering with dangerous, loathsome, and contagious diseases; epileptics, persons afflicted with tuberculosis, idiots, feeble-minded persons, polygamists, anarchists, immoral persons, and others of this character.
In the second place, what are known as alien contract laborers are prohibited from entering the United States, that is, persons who come under contract already entered into, to perform labor, whether skilled or unskilled. The law excluding this class was enacted in obedience to the demands of the union laborers of the United States, who did not wish to be subjected to competition with foreign laborers specially imported for the purpose. Actors, teachers, lecturers, and members of other professions are exempted from the law, and so are skilled laborers if domestic laborers of like kind are not available in the United States.
A third group of excluded classes are Chinese laborers, the immigration of whom was first prohibited in 1882.
A law of 1916 provides, with certain exceptions, that no alien shall be admitted unless he can read English or some other language or dialect. A law passed in 1921 limits the number of immigrants who may enter annually from each country, to 3 per cent of the number already in the United States, or a total of about 356,000.
There is now a head tax of eight dollars levied upon every immigrant who is admitted. Persons whose steamship passage has been paid by others or who have been otherwise assisted to come are not allowed to enter. When an immigrant has been denied admission by the commissioner of immigration at the port at which he has landed, he may take an appeal to a special board of inquiry. If the decision of this board is against him he may appeal to the United States commissioner-general of immigration, and finally to the secretary of the department of labor. If the final decision is against him, the steamship on which he sailed is required at its own expense to transport him to the port from which he sailed.
