International Copyright.—Formerly the writings of an American author might be republished in a foreign country without his consent, and thus he had no protection outside of his own country. Accordingly, to secure protection to American authors against the republication of their works in foreign countries without their consent, Congress enacted laws in 1891 and 1909, looking toward the reciprocal protection of American and foreign authors against infringement of the rights of each in the country of the other. In pursuance of these acts a copyright will be granted to a foreign author protecting him against the republication of his works in the United States, provided the government of which he is a subject will grant similar protection to American authors. But in the case of foreign books published in the English language the book must be printed and bound in the United States in order to secure the benefits of copyright. International copyright treaties designed to secure protection of this sort have been entered into between the United States and a number of foreign countries.

Patents.—A patent is a form of protection granted by the government to an inventor to secure to him for a limited period the exclusive enjoyment of the fruits of his skill and industry. Patents were granted by the state governments until the Constitution conferred this power on Congress. In 1790 Congress passed a law authorizing the granting of patents for new and useful inventions, and this law has been amended and its scope extended several times since.

The Patent Office.—In 1836, an office or bureau charged with receiving applications, conducting examinations, and granting patents was created in the department of state, but it was transferred to the department of the interior in 1849. This office has grown to be one of the largest and most important branches of the government service. It has a large number of examiners and experts arranged in groups, each of which examines the applications for patents for inventions of a particular class.

Conditions.—The applicant for a patent must declare upon oath that he believes himself to be the original inventor of the article for which he desires a patent, and he must submit with his application a full description or drawing of the invention, and if demanded, also a model of the same. The invention must be a useful one, for patents will not be granted for inventions which have no practical or scientific value. If the patent is refused by the commissioner of patents, the applicant can take an appeal to the court of appeals of the District of Columbia. A fee of fifteen dollars is charged for filing the application, and one of twenty dollars for issuing the patent.[49] The term for which a patent may be issued under the present law is seventeen years, which term may be extended only by act of Congress. When a patent is granted the word "patented" with the date on which it was issued must be placed on the article in order that the public may have notice of the fact that it is patented. During the term of the patent the inventor has the exclusive right to manufacture, use, or sell the article, and in case of infringement the law allows him to apply for an injunction to restrain the infringer, or to sue for damages. Patents, like copyrights, may be assigned or otherwise transferred, provided a record of the transfer is made in the patent office.[50]

Number of Patents Granted.—The inventive genius of the American people is shown by the large number of patents which have been issued since the first patent law was passed in 1790. The number granted during the year 1919 alone amounted to 37,259. The annual reports of the commissioner of patents, containing a list of the patents granted, together with specifications and drawings of the inventions for which patents have been issued, constitute a remarkable record of the growth of the country along industrial and scientific lines.

The Military Power of Congress.—The Constitution confers upon Congress the power to declare war, grant letters of marque and reprisal, and make rules concerning captures on land and water. In England and some continental European states the power of declaring war belongs to the crown, though the means of carrying it on must be provided by the legislative branch of the government. The framers of the Constitution, however, with their distrust of executive power, wisely left the whole matter to Congress. In the exercise of this power Congress has several times declared war against foreign nations.

A Letter of Marque and Reprisal is the technical term for a commission issued to an individual by a belligerent government authorizing him to prey upon the commerce of the enemy. The vessel commanded by a person holding such a commission is called a privateer. Privateering was long recognized as a legitimate mode of warfare, but the evils of the practice, due mainly to lack of control over the person bearing a commission of this sort, were so great that a congress of European nations held in Paris in 1856 declared privateering to be abolished. Although the United States has never formally adhered to this act, there is no likelihood that our government will ever again resort to privateering.

Captures.—In pursuance of the power to make rules concerning captures on land and sea, Congress has adopted a code of rules, though that matter is regulated for the most part by international law. Formerly it was the practice to allow the commander and crew a share of the proceeds of prizes captured on the sea in time of war, but in 1898 a law was passed abolishing prize money and providing that the proceeds from the sale of prizes should be turned into the treasury of the United States. In case of rebellion or insurrection the whole matter of the liability of the property of insurgents is within the control of Congress. Thus during the Civil War acts were passed for the confiscation of all property of the Confederates used in the prosecution of the war, as well as all abandoned property, that is, property belonging to persons who were away from their homes and in the Confederate service.

The Army.—The Constitution expressly authorizes Congress to raise and support armies, subject to the limitation that no appropriation for the support of the army shall be for a longer period than two years. This period corresponds to the term of Congress, and hence the limitation serves to keep the army under the control of the people. There was more or less jealousy of standing armies at the time of the adoption of the Constitution, and for a long time the regular army of the United States was very small; in 1898, for example, it was only 27,000 men.

Present Strength of the Army.—By an act passed in 1916 provision was made for increasing the peace strength of the regular army to 480,000 men; for establishing officers' reserve training corps at colleges and universities; for maintaining camps for giving military training to citizens who apply for it; and for creating a regular army reserve, the members of which are to receive at least fifteen days' training each year. Provision was also made for reorganizing the militia and for increasing its strength ultimately to about 425,000 men. The expense of the training camps and of equipping, training, and paying a small salary to the officers and men of the organized militia and of the regular army reserve is to be borne by the national government. After the beginning of the war with Germany (1917), provision was made for raising a large army by conscription of able-bodied young men between the ages of 21 and 31 years—later on between 18 and 45.[51] By the act of June 4, 1920, the strength of the regular army was reduced to 150,000 men on October 1, 1921.
