UNITED STATES OP AMERICA, a federated republic, composed of 88 independent states, eight organized and two other territories, and a federal district, occupies the central portion of the continent of North America, from hit. 24° 30′ to 49° 24′ N., long. 68° 50′ to 124° 45′ W., exclusive of Alaska. Its greatest length, from the Atlantic to the Pacific, is 2760 miles; greatest breadth, from Minnesota to Texas, 1600; northern or British frontier, 3540 miles; Mexican. 1550 miles; ocean coast, including the larger indentations. 12,609 miles, of which 6861 are on the Atlantic, 3461 on the Gulf of Mexico, and 2281 on the Pacific. The area of the U. S., as revised at the census of 1880. is 3.602,990 sq. in. The vastness of this territory will be best recognized by remembering that the total area of Europe is but little greater, being estimated at 3,826,000 sq. in. Texas, one of the states, is itself considerably greater in extent than the Austro-Hungarian Empire; and there are four other states or territories, each larger than the United Kingdom.
In 1783, the U. S. had an area of only 827,844 sq. in.; by the purchase of Louisiana from France in 1803, it acquired 1,171,931; by the cession of Florida by Spain in 1819, 59,270; by the annexation of Texas in 1845, 376,000; by the Oregon Treaty with Great Britain in 1846, 280,425; by the Mexican treaties, 677,260; and by the purchase of Alaska from Russia in 1867, 577,390 sq. m.
The 38 states composing the Federal Republic, each having its constitution, legislature, executive, and judiciary, and represented in the Federal Congress by two senators, and from 1 to above 30 representatives, according to its population, may be arranged in six groups, as in the accompanying table.
The eight organized territories are governed by the Federal Congress, with governors and judiciary appointed by the President of the U.S., but have a local legislature, and send a delegate without a vote to Congress. There is also the Indian Territory, a reserve for Indian tribes removed from the east of the Mississippi River; and unorganized region west of this, called Public Lands; the district of Columbia (60 sq. m.), ceded by Maryland, including Washington, the Federal capital, governed by Congress; and Alaska, under military rule. All these states and territories are described separately.
The original thirteen states are those which are marked in the table as having been admitted between 1787 and 1790. At the outbreak of the Civil War, there were fifteen slave-holding states; in the table they are the south-eastern and southern states, together with Nos. 10, 11, 12, and 27 (11 being then part of 13). In 1881 the preliminary steps were taken for having the southern half of Dakota delineated as a new territory, with the name of Pembina.
Physical Character.—Though occupying the central portion of a continent, more than two-thirds of the frontiers of the U. S. are shores of lakes and oceans, with numerous bays and sounds, rivers, and lakes. The principal lakes, besides those divided with British America, are Lake Champlain, Lake Michigan, Great Salt Lake, Pyramid Lake, Mono Lake. Lake Tulare. and many beautiful clusters of smaller lakes in Maine, New York, Minnesota, &c.
The rivers of the U. S. may be classed in four divisions : 1. The Mississippi and its branches (q. v.); 2. The rivers emptying into the Atlantic or its bays and sounds—the St. Croix, Penobscot, Kennebec, Merrimac, Connecticut, Hudson, Delaware, Susquehanna, Potomac, James, Roanoke, Neuse, Cape Fear, Pedee, Santee. Savannah, Altamaha, St. Johns, &c.; 3. Those, besides the Mississippi, emptying into the Gulf of Mexico—the Chattahoochee, Alabama, Tombigbee, Pearl, Sabine, Trinity, Brazos, Colorado, Nueces, and Rio Grande; 4. Those emptying into the Pacific—the Oregon or Columbia, Sacramento, San Joaquin, Colorado, &c. Besides these, there are many small rivers emptying into the great lakes, and finding their outlet through the St. Lawrence; and the rivers which empty into the salt lakes of the great interior basin of Utah.
The chief mountains of America are those of the Alleghanies and the Rocky Mountains; for the extraordinary scenery of the west, see YELLOWSTONE; also COLORADO and YOSEMITE.— The geology of the U. S. will be found under the titles AMERICA, APPALACHIANS, ROCKY MOUNTAINS, and the several states.— The soil is of every variety, from the sterile deserts of the great western plains and Utah, to the inexhaustible fertility of the bottom-lands of the Mississippi Valley, where heavy crops of maize have grown for fifty successive years without manuring. The St. Lawrence basin is an elevated calcareous plain, fertile and well wooded. The Atlantic slope from Maine to New Jersey, east of the Hudson, is hilly, and best adapted for grazing; more southerly, the coast-belt is low, sandy, in places swampy, with pine-barrens, the inland region fertile, and among the best in the country. The Mississippi valley is generally level, and prairie-land of unsurpassed fertility, with a rich mould, in places 25 feet deep. North-west, the country rises to a high and sterile region, extending from 200 to 400 miles from the base of the Rocky Mountains. The Texas slope has rich bottom-lands on the coast, a fine rolling fertile country, rising to a high plateau, dry and sterile, except in the river-bottoms. The Pacific slope is generally sterile, except the great valleys between the mountain-ranges, and bordering the rivers, which are of great fertility.
Utah, with the exception of a few fertile spots, is a desolate untimbered region of salt lakes and land saturated with alkaline substances. The country east of the Mississippi, except the prairies of Illinois and Indiana, was, at its settlement, heavily wooded, and there are still vast forests of valuable timber—beech, birch, maple, oak, pine, hemlock, spruce, walnut, hickory, ash, elm, &c-; and in the south, live oak, water oak, magnolia, palmetto, tulip-tree, cypress, cotton-wood, cane, &c. West of the 97th meridian stretches a vast region of almost treeless prairies; forests again occur in the Rocky Mountains, and California, Oregon, and Washington Territory have the largest timber in the world. The flora and fauna will be found under the head NORTH AMERICA (Botany. Zoology), and the several states.
Population.—The growth of the population will be best seen from the table, which shows the rapid increase of the inhabitants of the Republic at various censuses from 1800 to that of 1880. How far this is due to foreign immigration is shown by some appended figures. It is to be noted that the census figures for the various states do not include in their totals, the tribal or wild Indians within their limits. These are estimated apart, but the civilized or settled Indians are reckoned along with their neighbors of European stock. A separate column shows the number of the colored persons.
At the census of 1880 there were 64 cities in the U. S. with between 20,000 and 50,000 inhabitants; 15 between 50.000 and 100.000; 10 between 100.000 and 200,000; 3 between 200.000 and 300,000; 3 between 300,000 and 400.000; 2 between 400,000 and 500,000; 1 (Philadelphia) over 800,000; and 1 (New York) with upwards of 1,200,000. It was found that of the 18 most populous cities of the U. S., 6 had increased since 1870 by from 20 to 30 per cent. 4 from 30 to 50, 4 from 50 to 71, and 1 (Milwaukee) 92 per cent.
No country has been peopled by such a variety of races. New England was settled by English Puritans, and a few Scottish and Welsh; New York, by Dutch; Pennsylvania, by Quakers and Germans; Maryland, by English Roman Catholics; Delaware and New Jersey, by Dutch and Swedes; Virginia, by English cavaliers; the Carolinas, in part by French Huguenots; Louisiana, by French; Florida, Texas, and California, by Spanish; Utah, by Mormons, chiefly from England, Wales, and Denmark. Immigration from Ireland, Germany, England, Scotland, France, Switzerland, Sweden has been large and progressive. Of the total of 50.155.783 reckoned in the census, 25.518,820 were males, and 24,636,963 females; 43,475,840 were native born, and 6,679,943 were whites, foreign born, 105,465 were Chinese, 148 Japanese, and 66,407 were civilized Indians. The table shows separately the tribal Indians, and the occupants of the Indian territory. Of the whites foreign born, 2,772,169 were natives of the United Kingdom; 1,966,742 were Germans; 717,084 British Americans; 194,327 Norwegians; 181,729 Swedes; 106,971 French. It is said that the Irish and the Germans, with their descendants
constitute one-third of the entire population; about 10,000.000 being set down as of Irish descent, and 6.000,000 of German stock. From 1820 to 1880, the immigrants from Great Britain and Ireland numbered over 4,700,000. The current of immigration which goes to swell the grand total is very large, but fluctuates from year to year. Between 1870 and 1880 it varied from 138.000 in 1877, to 457.000 in 1880; in 1881 it reached the enormous aggregate of 669,431.

Climate.—For a particular account of the climate of the U. S., we refer to the articles RAIN and TERRESTRIAL TEMPERATURE. It is remarkable for wide transitions of cold and heat, rain and drought, except in the peninsula of Florida, where the temperature varies but 12° F., and Western Oregon and Washington Territory, where the climate is like that of England. With few exceptions, the summers are hot, both north and south, the thermometer rising at times to 110° F., and along the northern range of states sinking to—20°, and even sometimes as low as— 40°. The whole Atlantic coast has a winter temperature 10° lower than that of Western Europe in the same latitude. Thus, at New York, in the latitude of Madrid, the Hudson River is frozen, and the harbor at times filled with floating ice.
The causes modifying the climates of the different portions of the states chiefly arise out of the physical features; of which the Rocky Mountains, the Gulf of Mexico, the Atlantic, and the lake system in the north are the most prominent. On the west, from the shores of the Pacific to the Cascade Mountains, one of the most important ranges of mountains in America, the climate resembles that of Great Britain more closely than that of any other country in the world, being mild and humid, with frequent showers at all seasons. But the great valley lying between the Cascade and the Kooky Mountains is almost entirely a rainless district, because the westerly winds are drained of their moisture in crossing the Cascade Mountains before arriving there. In winter, it is covered with snow, but in summer is dry and arid. Owing, however, to the copious streams poured down from the melting snow, it presents abundant facilities for irrigation, so that its capabilities and resources are great, if they were properly developed. The country east of the Rocky Mountains depends for its rain on the Gulf of Mexico; and the rainfall there is distributed most in the low plains, and least on the plateaux and mountains. Hence over this extensive district southerly winds are warm and moist, and westerly and northerly dry and cold.
The result is rapid alternations of temperature, such as are never experienced in Western Europe, the temperature having frequently a range in the course of a day of 50° or 60°. In the New England states, the northerly and easterly winds are cold moist, and chilly, accompanied with frequent fogs; otherwise the climate resembles that of Great Britain. The climate of the states surrounding the great lakes in the north is mild and moist in summer as compared with the other northern states; but in winter, when the lakes are frozen over, a degree of cold is experienced greater, absolutely and relatively, then anywhere else in the states. This excessive cold is caused by the country being exposed in the north to the full sweep of the polar current from the north; but more particularly to its low-lying situation, thus forming, as it were, a vast basin into which is poured from all sides the cold, and therefore heavy, currents of air chilled by terrestrial radiation during the winter season.—The health of the U. S. varies with climate, elevation, &c. Swamps and river-bottoms in some regions, especially the more fertile, are malarious. The rice-swamps of Georgia and Sooth Carolina are fatal to whites, but not to negroes. In vast tracts of new country, even the rolling and hilly, the disturbance of the soil causes intermittent fevers. Diseases of the lungs prevail in the northern and middle states, bilious fevers in the southern; in the western, intermittent and remittent bilious.
In 1850, the average mortality was 1 in 72, varying rather widely in different regions, modified not only by climate, but by the presence of large towns, and by immigration and emigration. In 1870, the lowest rates of mortality were 0′69 per cent, in Oregon, 0′80 in Minnesota, and 0′81 in Iowa; the highest were 1-77 per cent, in Massachusetts (with numerous manufacturing towns), and 2 in Louisiana (with yellow fever). Of the larger cities in 1880, Charleston had a death-rate of 32 per 1000, New York, 26; Baltimore, Brooklyn, and New Orleans, 24; Boston, 23; Washington, 22; Cincinnati, Cleveland, Chicago, and Philadelphia, 20; San Francisco and St. Louis, 19. Probably no portion of the world is more salubrious than Vermont, the eastern slope of the Alleghanies, California, and Oregon.
Mineralogy.—The U. S. are rich in mineral productions. Coal is found in every state except Maine, New Hampshire, Vermont, New Jersey, Delaware, South Carolina, Louisiana, Mississippi, Minnesota, Wisconsin, and Nevada. The area of the coal-measures is estimated at 300,000 sq. miles. The whole extent of the coal area in the U. S. has been divided into four principal coal-fields or tracts—viz., the Great Central Alleghanian or Appalachian coalfield, extending from Alabama, through Eastern Tennessee and Kentucky, Western Virginia, Maryland, Ohio, Pennsylvania, and reappearing in New Brunswick and Nova Scotia. This field has been computed to cover within the U. S. an area of 50,000 to 60,000 sq. m., of which about 40,000 sq. m. are considered workable area.
The second coal-field occupies the greater part of Illinois and Indiana, and in extent is nearly equal to the first. A third field covers a large portion of Missouri; and the fourth, of Michigan. The Chesterfield bituminous coal-field, a small district near Richmond, contains the oldest collieries in America. The petroleum springs form a source of great wealth. Beds of rich marl are found in several of the eastern states, and in many, nitrates and carbonates of soda, and potassia, gypsum, and marble of great variety, and some of rare beauty. Iron is found everywhere, from the pure metal in mountain masses, to bog-ore; and in many places in close proximity to coal. Lead exists in rich deposits in Missouri, Arkansas, Illinois, and Iowa. Copper is found in several states, and in great quantities of ores of 71 to 90 per cent, on the borders of Lake Superior. Zinc exists in New Jersey and Pennsylvania, and tin in Maine and California. There are rich silver mines in Colorado, Nevada, Utah, New Mexico, Arizona, and California. Gold is found in small quantities in some of the Atlantic coast states; in great quantities in California, Oregon, Colorado, Nevada, Washington, Arizona, New Mexico, and Montana. There are also found platinum and mercury in California, osmium and iridium in Oregon, cobalt in North Carolina and Missouri, and nickel in Connecticut and Pennsylvania. The value of the produce of American mines increased by 90 per cent, in the period 1870—1880, and amounted in the latter year to 72 millions sterling. Over 91 millions of tons of iron ore were raised in 1880 (more than twice as much as in 1870); 20,300 tons of copper ore; 66 millions of tons of coal; and 860 millions of gallons of petroleum (20 times as much as in 1870). A value of $34,700,000 of gold was obtained in 1881, and $43,000,000 of silver.
Agriculture.—Agriculture holds the first place in the national industry. In 1871, the acreage of hay was 10.009.052; maize, 34,091,137; wheat, 19,943.893; oats, 8,365.800. The average size of farms, nearly all held by their cultivators in fee-simple, was 153 acres. In 1880, the acreage of maize was 52.965.000 acres, and of wheat, 36,000,000. The cereal crops of 1879 and 1880 were the largest ever known. The production of wheat in 1879 was 448,-000,000 bushels, in 1880 it was 480,000.000; and of maize, 1,577,000 were produced in 1880. The advance in production between 1870 and 1880 was unprecedented, amounting to about 100 per cent., taking all kinds of grain produce; whereas, in 1860 to 1870, it was but 12 per cent. The production of cotton advanced from 1540 million lbs. in 1870 to 2773 millions in 1880. More than two-thirds of the world’s cotton crop is grown in the states. Till 1859 the U. S. used occasionally to import wheat from Europe; now they produce one-fourth of the world’s crop, and have a yearly surplus of 150.000,000 bushels. Between 1870 and 1880 the horses in the U. S. increased from 8,690.000 to 12.550,000; cows from 28,000,000 to 33,600.000; sheep from 28.500,000 to 38,000,000; hogs from 25.200,000 to 35.000,000. The shipments of cattle and meat from the U.S., which have enormously increased of late, exceeded, in 1880, the value of $25.000:000. The wine produce has steadily increased to about 20,800.000 gallons. Other important agricultural products are sugar, rice, tobacco, and vast quantities of fruits, varying in the various sections of the Republic. It has been estimated that the animal income of the U.S. from agricultural industries is about $3.000.000.000. as compared with $1,900,000,000 for France, and $1,325,000,000 for the United Kingdom.
Fisheries.—The fisheries of the U. S. employ from 800.000 to 1,000,000 persons, and give an annual yield of $27,300.000 (the yield of the British fisheries alone exceeding this aggregate ) Pisciculture is diligently and most scientifically practised and with the best results.
Manufactures.—The manufactures of the U. S. increased about 30 per cent, in the period 1870 to 1880. In the making of flour, the states are foremost in the world, the annual product being nearly 4i billion dollars. In regard to textile manufactures’, they come next after England, and make about one-sixth of the entire produce of the world. Between 1870 and 1880 the consumpt of cotton rose from 530 million lbs. to 911 millions, and of wool from 204 to 258 millions. In 1880, the combined produce of cotton and woollen manufactures in the U. S. was valued at $420,000,000. The total silk manufactures are valued at $34,000,-000. The progress of iron and steel is marvelous; iron having risen in the past decade from 1,580,000 to 4,290,000 tons a year, and steel from 40,000 to 800.000 tons (both these quantities being-surpassed by Great Britain). The Americans now make one-fifth of the iron, and one-fourth of the steel of the world. The flour trade employs 3,000,000 workmen, and textile manufactures 3.500,000. The chief manufacturing states are Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, and Maryland.
Commerce.—The total value of imports into the U. S. rose from $462.380,000 in 1870 to $760.990.000 in 1880; that of exports of American produce, from $420,500,000 to $841.501,000 (the coin and bullion imported in 1880, $93,000,000, exceeding that exported, $85,240,000). The imports from Great Britain and Ireland were nearly $175,000,000 in 1870, and a little over $154,000,-000 in 1880; the exports thither were only $305.000,000 in the former year, and $535,000,000 in the latter. The chief imports into the United States are cotton goods; iron, wrought and un-wrought; linen and woollen manufactures. The chief exports are wheat and flour, cotton, tobacco, pork and hams, butter and cheese. More than one half of the exports of the U. S. go to the United Kingdom, the rest mainly to Canada, France, and Germany. Port entries of the U. S. doubled between 1870 and 1880 (16,193,000 tons entered in 1879); and the value of the carrying trade by land and sea has advanced greatly, though the shipping on the high seas has declined from $43,000″000 to $40.500,000.
Railways, &c.—The U. S. possesses an enormous extent of navigable rivers, canals, and railways. The Mississippi and its branches afford 20,000 miles of steamboat navigation. Canals unite the waters of the Hudson River with Lakes Champlain, Ontario, and Erie in New York, the Delaware and Susquehanna rivers in Pennsylvania, the Ohio with Lake Erie in Ohio and Indiana, and the Mississippi with Lake Michigan in Illinois. Other canals make with these an extent of 3500 miles. Railways extend from the lakes to the Gulf of Mexico, and from the Atlantic to the Pacific. There were in operation in 1880, 85,000 miles of railway. Railways have doubled in ten years. New main lines of communication are the Southern Pacific (from Galveston by Topeka and Santa Fe), and the Northern Pacific, from St. Paul to the west.
Education and Religion-—The benevolent, literary, and scientific institutions of the U. S. are generally state institutions, accounts of which will be found under the heads of the respective states. The exceptions are the Smithsonian Institute (q. v.), American Association for the Advancement of Science, the National Academy of Sciences, and military and naval academies and hospitals.—In the U. S. are about 350 colleges (including UNIVERSITIES, q. v.), 120 theological seminaries, 100 medical schools, 40 law schools, great numbers of academies or high schools, and female seminaries. Free common schools are established in nearly all the states, sufficient for universal education, supported by taxes, school funds, and, in all the new states, the reservation of one or two sections of land, of 648 acres each, in every township. In 1880, there were near 4000 public libraries, with near 18,000,000 volumes (including in the total the district school libraries). Literary societies abound, and courses of lectures are largely provided. The press is very active. In 1871, there were 6056 periodical publications (637 daily); in 1881, there were above 8000 (1000 daily).
Religion is free from any interference of either the Federal or state governments, and all denominations exist in entire freedom upon the voluntary principle. The numbers of the principal religious denominations were as follows in 1880 :

Constitution, Government, &e.—The government of the U. S. is one of limited and specific powers; strictly defined by a written constitution, framed by a convention of the states in 1787, which went into operation after being ratified by the thirteen original states in 1789, by which instrument the several states, having their independent republican governments, conferred upon a Federal Congress, executive, or President, and judiciary, such powers as were necessary to ‘ form a more perfect union, establish justice, insure domestic tranquility, provide for the common defence, and secure the blessings of liberty.’ The legislative powers granted to the Federal government are vested in a Congress of the U. S.. consisting of a Senate of two senators from each state, chosen by the legislature thereof; and a House of Representatives, consisting of one or more members from each state, elected by all male citizens over 21 years of age; so that the states, large and small, have each 2 votes in the senate, and from 1 to above 30 in the House of Representatives, which consists, after 1883, of 325 members, or 1 to 154.325 of population (In 1873, 293 members). The senator must be 30 years old, and is chosen for 6 years; the representative 25 years old, and for two years. Senators and representatives, by an act of Congress passed in 1874, are paid $5000 per annum, with traveling expenses. The Senate is presided over by the vice-president; and is a high court for trial of cases of impeachment.
It also confirms the appointments of the President, and ratifies treaties made with foreign powers. Revenue bills originate in the House of Representatives. Bills passed by both Houses, within the limits of their constitutional powers, become laws, on receiving the sanction of the President; or, if returned with his veto, may be passed over it by two-thirds of both Houses.
By the constitution, the states granted to Congress power, ‘ to lay and collect taxes, duties, imports, and excises, to pay the debts, and provide for the common defence and general welfare of the United States;’ to borrow money; to regulate commerce; to establish uniform naturalization and bankruptcy laws; to coin money, and fix the standards of weights and measures, and punish counterfeiting; to establish post-offices and post-roads; to secure patents and copyrights; punish piracies; declare war; raise armies and navy; to call out the militia, reserving to the states to appoint their officers; and to govern the district of Columbia, and all places purchased for forts, arsenals, &c., with the consent of the state legislatures. All powers not expressly granted are reserved to the states or the people; but the states, though sovereign and independent under the constitution, with all powers of local legislation, eminent domain (i. e.,. absolute possession of the soil), and power of life and death, with which neither President nor Congress can interfere, cannot make treaties, coin money, levy duties on imports, or exercise the powers granted to Congress.
The executive of the Federal government is a President, chosen by an electoral college, equal in number to the senators and representatives, elected by the people of the states. He must be a native of the U. S., 35 years old, and is elected for a term of four years, and may be re-elected without limit. His salary is $50.000 a year. The Vice-president, who, in case of the death of the President, succeeds him, is President of the Senate. If he should die after becoming President, his successor would be chosen by Congress. The President, by and with the consent of the Senate, appoints a cabinet, consisting of the Secretaries of State and Foreign Affairs, Treasury, War, Navy, Interior, the Postmaster-general, and Attorney-general. These officers have salaries of $8000 a year, have no seats in Congress, and are solely responsible to the President, who also appoints directly, or through his subordinates, the officers of the army and navy—of which he is commander-in-chief—the justices of the Federal judiciary, revenue-officers, postmasters, &c.—in all about 100,000.
The judiciary consists of a supreme court, with one chief-justice and seven assistant-justices, appointed by the President for life, and district judges in each district. The supreme court has jurisdiction in all cases arising under the constitution, laws, and treaties of the U. S.; causes affecting ambassadors and consuls, of admiralty and jurisdiction; controversies to which the U. S. is a party, or between a state and the citizens of another state, citizens of different states, citizens and foreign states. It has original jurisdiction in state cases, or those affecting ambassadors or consuls— in others, appellate. A person may be tried for treason, both against the federal government, and against the state of which he is a citizen. The President can reprieve or pardon a person condemned by a Federal court; but has no power to interfere with the judgments of state tribunals. Besides the supreme court, there are U. S. district courts, with judges, district attorneys, and marshals, in districts comprising part or whole of the several states. The citizens of each state are entitled to all privileges and immunities of the several states. Criminals escaping from one state to another are given up for trial on demand of the executive; and the constitution declared, before the rebellion, that ‘ no person held to service or labor in one state, under the laws thereof, escaping into another, shall, in consequence of any law or regulation therein, be discharged from such service or labor, but shall be delivered up on claim of the party to whom such service or labor may be due.’ The constitution may be amended by a convention called at the request of two-thirds of the states; or amendments may be proposed by a vote of two-thirds of Congress, and ratified by three-fourths of the states; but ‘ no state, without its consent, shall be deprived of its equal suffrage in the Senate.’
The President, either directly or through the Secretary of State and Foreign Affairs, appoints ministers, consuls, and consular agents to foreign countries. The envoys-extraordinary and ministers-plenipotentiary receive from $17.500 to $10,000 of salary; ministers resident have $7500 to $4000.
Army and Navy.—The army of the U. S., under the command of the President, consisted, in 1790, of 1260 men. In 1861, its numbers were 14,000, and those who took part with the Confederates, or were disbanded in the Confederate States, reduced the number to about 5000. April 15, 1861, 75,000 volunteers were called out; May 4, 64,000; July and December 1861, 500,000; July 1, 1862, 300,000; August 4, 1862. 300,000; summer of 1863, 300,000; February 1, 1864, 500,000. The total number called out from 1861 till the end of the war in 1865, was 2,670,874. This vast army was procured by volunteering, by enlistment in the regular army, and by drafts or conscriptions; but the greater part by bounties of 300 to 1000 dollars to each volunteer. Large numbers of recruits were also found among newly arrived immigrants; and the negro troops recruited in the seceded or slave states, ill October 1863, numbered 38,707, and increased in numbers to the end of the war. In 1871, the regular army was reduced to the legal standard of 30,000 enlisted men, and it was subsequently enacted that from 1875 there should be no more than 25,000 men enlisted at any one time. The militia of the U. S. is under the state governments, but is not organized. There are numerous arsenals and manufactories of arms at Springfield (q.v.). Massachusetts; Pittsburg- (q. v.), Pennsylvania, &c. The Military Academy at West Point educates cadets, nominated from each state by members of Congress, and appointed by the President, who receive commissions as officers in the army.
The navy of the U. S. in 1880 consisted of about 60 cruising-ships. 20 monitors, and 2 torpedo-boats. The iron-clad turret-steamers (see TURRET-SHIP) called monitors, constitute a powerful portion of the American navy. A Naval Academy has been established at Annapolis, Maryland, for the education of naval cadets.
The Post-office Department, organized before the “Revolution of 1775 by Benjamin Franklin, had in 1880 over 44,500 offices, and forwarded 868,493,500 letters; 276,450,000 post-cards; 695,000,000 newspapers; 53,472,000 magazines; books, &c., 300,855.000; articles of merchandise, 22,645,000. There were, in the same year, 11,317 telegraph offices, with 107,103 miles of lines, which forwarded 30,486.000 messages.
Revenue, Expenditure, &c.—The following table gives the expenditures (excepting interest on debt), and the debt of the U. S., for 20 different years :

Of late years the surplus revenue has come to be so great that it has been an embarrassment; the debt has been swiftly reduced; and it has been a problem whether to reduce internal duties (on tobacco, spirits, &c.), or customs, but the prohibition system is maintained. The expenditure of 1881—1882 (chief items, legislation, executive, civil list, army, navy, post office, pensions), was $216,694.384, and left near $150.000,000 of surplus; 1880—1881, the surplus was $100,000,000.
The revenue of the U. S. up to the War of Secession. 1861, was drawn almost wholly from the sale of public lands and duties on imports. In 1850, the revenue from customs was $39.668.686; from lands, &c., $3,707,112—total, $43,375,798. In 1850 the revenue from customs was $53.187,511; lands, &c., $2.877.691— total, $56,064,606. The cost of the war compelled the government to add to these resources a system of internal revenue or direct taxation, consisting of stamps, licenses, excise, income-tax, &c., by which the revenues were increased in 1865 to $309,510.-932. The revenue for the year 1879-80 amounted to $333,526,610 (£66,705,000), the principal items being customs, $186,000,000. and internal revenue, $124,000.000. The expenditure was $267,642,955 (£53.528,600). The total debt in 1880 amounted to £422,-407,182; from 1865 to 1880, the nation had paid off the immense sum of £170.000,000. In the fiscal year 1879-80. the debt was reduced by £13,176,000. In 1865, owing to the Civil War, the debt per head was about £16; but in 1880 it had been reduced to about £8, 8s. per head.
The currency of the U. S. is a mixed one of gold, silver, and copper, and bank-notes. Specie was for many years the only money recognized by the Federal government; paper money being issued by chartered banks. The war of 1861—1865 compelled the government to issue paper-money, and to establish national banks, in 1871, for its circulation. The capital of state banks in 1880 was $456,000,000, and of private banks upwards of $190,000,-000, In 1878 a law was passed making silver equally a legal tender with gold, though silver was then 11 per cent, less in value. Specie payments were resumed by the government in 1879.
The specie currency of the U. S. consists of the gold dollar (value in exchange about 4s. sterling); the half-eagle, $5; the eagle, $10; the double eagle, $20; silver-dollar, half-dollar, quarter; dime, 10 cents; half-dime; nickle cent, or 100th part of a dollar. The coinage of 1880 was—gold $56,157,735; silver, $27,942,437; copper, $269,971; from the establishment of the mint to June 30,1880, $1,133,103,322.
