The opening up of a new frontier is world-wide in its operations. Minnesota entered the union as a State in 1858. The putting to practical use the Falls of St. Anthony was felt all over Europe. Thousands of little country mills, nestling amid the trees, and adding to the beauty of the English pastoral scenery, to-day stand idle, the great wheels covered with green moss; and Tennyson\'s "Miller" becomes a reminiscence. Iowa became a State in 1846, and now leads the world in the production of corn; and although it[2] is a thousand miles from the seaboard, yet through its immense production, and with the cheapening of transportation, we find over seventy thousand Italians emmigrating to this country, as, in spite of low wages, they cannot compete on the plains of Lombardy. (See Wells\'s "Economic Changes.")—We find that the man at the front can ship from Chicago to Liverpool the product of five acres of grain for less money than the cost of manuring one acre of land in England. (Ibid.)

Every time a new frontier in America is opened, it means both prosperity and disaster. So large are the opportunities, so rich the results, that at first all calculations are upset. Natural gas in the Middle States changes the price of coal in Europe. The finding of a tin-mine is felt in Cornwall and Wales the next day. The opening of the iron-mines in Michigan makes Cornish towns spring up in the upper peninsula, while the finding of ore in desolate places has caused communities to[3] spring up with all the conditions of a cosmopolitan civilization, and we have to-day men living twenty-five miles from trees or grass. But such is the energy of the frontier type, that grass-plats have been carried and planted on the solid rocks, as in Duluth, where hundreds of thousands of dollars are expended in the grading of streets, and the opening of the sewers, all having to be blasted to do the work.

North Dakota was a wilderness of 150,000 square miles, and had not produced a single bushel of wheat for sale, in 1881. In 1886 it produced nearly 35,000,000 bushels; in 1887, 62,553,000. (See Wells\'s "Recent Economic Changes.") The opening up of these immense territories starts railways from California to Siberia; for, with the Great West competing, Russia is stirred to greater effort. India, with her great commerce with Great Britain, needs a shorter route; and the Suez canal is made. Australia must compete with the Western plains; and great steamers, filled with refrigerators, are constructed for[4] carrying fresh beef. The South American republics respond in return.

The hardy pioneer, ever on the move, explores well nigh impracticable routes in search of precious metals. The inventive mechanic must respond with an engine that can climb anywhere; and in almost inaccessible mountain eyries the eagle is disturbed by the shriek of the locomotive, and the bighorn must take refuge with the bison in the National Park. The news of new mines flies around the world, fortunes are made and lost in a day, and the destinies of nations determined. A great crop starts railways, steamships. Miners, smelting-works, iron and steel, respond. Letters fly across the Atlantic, and returning steamers are filled with eager men and women, who answer the letters in person. Down from the far north, Sweden and Norway have responded with over a million of their children. Great Britain has sent nearly six millions. Germany follows with 4,417,950; Italy, 392,000; France, 315,130; Austria, 304,976; Denmark, 114,[5] 858; Hungary, 141,601; Switzerland, 167,203; Russia and Poland, 326,994; Netherlands, 99,516; and so on: in all, a total for Europe in fifty years of over 13,000,000, the great majority of whom have been started from their homes by the opening up of new frontiers.

It has been stated on good authority, that sixty per cent of the Germans that come are between the ages of fifteen and forty, while all Germany has only thirty per cent of that age.

On the authority of Dr. Farr, quoted by R. Mayo Smith in his "Emigration and Immigration," he calculates the money value of the immigrants from the British Isles from 1837 to 1876 reached the enormous sum of 1,400,000 pounds sterling, or 7,000,000,000 of dollars, an average of 175,000,000 dollars a year; while the amount sent back from British North America and the United States since 1848 was but ￡32,294,596. And what has been produced by the immigrant and exported amounts to many hundred millions[6] of dollars. It has been computed that the country has been pushed forward a quarter of a century by this vast mass of immigrants, nearly all of whom labor for a living.

The frontiers of America will yet change the world. When in the not distant future hundreds of millions cover the great continent, dotted with schools and churches, and an intelligent population speaking one language, and with other millions in Africa, Australia, and the islands of the sea, using the same language, the time will come when they will arbitrate for the world, and war shall be no more. Long before the Atlantic cable was stretched across the ocean, millions of heartstrings were vibrating from this land to all parts of Europe; and to-day the letters fly homeward from the frontier immigrants in their sod houses, bearing good cheer in words and money.

The freedom of the frontier is contagious, and the poor European strives harder than ever to reach his kin across[7] the sea. And when we consider that only 300,000 square miles out of 1,500,000 miles of arable land is under cultivation, and that already the farmers of England and most parts of Europe are being pushed to the wall, we begin to realize that the growth of the frontiers of the United States not only influences our own land, but changes materially the course of events in the whole world. The above figures are by Mr. Edward Atkinson, as quoted in substance from "Recent Economic Changes."

To show the growth of one State during the past fifty years, let us take Michigan. In 1840 Michigan had a population of 212,267; in 1890, 2,093,889. In 1840 there were three small railroads, with a total mileage of 59 miles. In 1890 there were over 7,000 miles. "In 1840 [I quote from Hon. B. W. Cutcheon, in "Fifty Years\' Growth in Michigan"] mining had not begun. In 1890 over 7,000,000 tons of iron were shipped from her mines; while the output of copper had reached[8] over a 100,000,000 lbs., and valued at $15,845,427.28. The salt industry, a late one, rose from 4,000 bbls. in 1860 to 3,838,937 bbls. in 1890; while the value of her lumber products for 1890 was over $55,000,000. In 1840 there were neither graded nor high schools, normal schools nor colleges. In 1890, 654,502 children were of school age, with an enrolment of 427,032, with 33,975 additional attending private schools. These children were taught by 15,990 teachers, who received in salaries $3,326,287."

In 1840 Michigan had 30,144 horses and mules, 185,190 neat cattle, 99,618 sheep. In 1890 there were 579,896 horses, 3,779 mules, of milch cows 459,475, oxen and other cattle 508,938, of sheep 2,353,779, of swine 893,037. The total value came to $74,892,618. Over 1,700 men are engaged in the fisheries, with nearly a million dollars invested, with a total yield of all fish of 34,490,184 lbs., valued at over a million and a half of dollars. The value of her apples and[9] peaches in 1890 was $944,332; of cherries, pears, and plums, $65,217; of strawberries, $166,033; of other berries, $267,398; and of grapes, $122,394. The wheat crop for 1891 was valued at $27,486,910; the oats at $9,689,441; besides 811,977 bushels of buckwheat, and 2,522,376 bushels of barley. The capital invested in lumber alone was $111,302,797. "While her great University, which saw its first student in 1841, and which had but three teachers, one of them acting as president, has grown to be one of the largest in the nation, with eighty professors and instructors and 2,700 students registered on her rolls, conferring 623 degrees upon examination." And all this but the partial record of fifty years in one State.

Since Michigan was entered as a State fourteen new States have been formed (not counting Texas) and three Territories, with an aggregate of over 17,000,000 square miles of land, and a population of nearly 15,000,000, nearly all of which[10] fifty years ago was wilderness, the home of the Indian and the wild beasts. With such stupendous changes in so short a time, we see that the American frontiers have a direct and powerful influence in changing the histories and destinies of the nations of the whole world.
