It was one of the great disappointments of Carleton's life that, on returning from his journey around the world, he was not made, as he had with good reason fully expected to be made, chief editor of the Boston Journal. We need not go into details of the matter, but suffice it to say, that Carleton was not one to waste time in idle regrets. Indeed, his was a character that could be tested by disappointments, which, in his life, were not a few. Instead of bitterness, came the ripened fruit of patience and mellowness of character.
His renewed acquaintance with the region west of the Mississippi, which he had made during his recent trip across the continent, only whetted his appetite for more seeing and knowing of the future seat of America empire. He accepted with pleasure a commission to explore the promising regions of Minnesota and Dakota, and to give an account especially of the Red River Valley.
Already, in 1858, he had written and published, at his own expense, a pamphlet of twenty-three pages, entitled "The Great Commercial Prize," Boston, A. Williams & Co. It cost him fifty dollars, then a large sum for him, from which the advantage accrued to the nation at large. It was addressed to every American who values the prosperity of his country. It was "An inquiry into the present and prospective commercial position of the United States, and a plea for the immediate construction of a railroad from Missouri River to Puget Sound." It opens with a review of the great events in the world which have had a direct and all-important bearing upon the United States. Hitherto, since the modern mastery of the ocean through the mariner's compass and the science of navigation, the Atlantic had been the domain of sea power. The Pacific was in future to be the scene of greater opportunities and grander commercial developments. With China and Japan entering the brotherhood of nations, and Russia extending its power towards the Pacific, "five hundred millions of human beings were henceforth to be reached by the hand of civilization." The countries and continents bordering the greatest of oceans were animated with new ideas of progress. On our own western shores, California, Oregon, and Washington were awaiting the touch of industry to yield their riches.
As a reader of the signs of the times, Carleton pointed out the great changes which were to take place in the thoroughfares of trade and travel. Instead of civilization depending for its communication with India, China, and Japan, by passages around the southern capes of the two continents, the paths of water and land traffic were to be directly from China, Russia, and Japan to northern America. Noticing that England had made herself the world's banking-house, he saw that the time had come when the United States (which he believed to be potentially, at least, a larger and a nobler England) must stretch out her left hand, as well as her right, for the grasping of the world's prizes. He pointed out the wonderful openings along the shore, providing harbors at the mouths of the two great river systems on the Pacific Coast, those of the Sacramento and the Columbia.
Carleton urged that "A railroad to Puget Sound, constructed immediately, alone will take the key of the Northwest from the hands of the nations which stand with us in the front rank of power." Important as the railway to San Francisco was, it would not yield the prize. To his vision it was even then perfectly clear, as to all the world it has been since the Chino-Japanese war of 1894-95, that the chief American staple which China and Japan needs is cotton, though machinery, petroleum, and flour are in demand. After giving facts, statistics, and well-wrought arguments, he wrote: "Again we say it is easy for America to lay its hand upon the greatest prize of all times, to make herself the world's workshop,—the world's banker. Shall England or the United States control the northwestern section of the continent and the trade of the Pacific?"
Over a decade later on, in 1869, Carleton revelled in the opportunity of being once more the herald and informer concerning regions ready to welcome the plough, the machine-shop, the home, the church, the school, and the glories of civilization. He spent several months mostly in the open air and chiefly on horseback, though often on foot and in vehicles of various descriptions, camping out under the stars, or accepting such rough accommodation as was then afforded in regions where palace cars, elegant hotels, and comfortable homes are now commonplaces. His letters to the Journal were breezy and sparkling. They diffused the aroma of the Western forests and prairies, while marked with that same wealth of graphic detail, spice of anecdote, lambent humor, and garnish of a conversation which delighted the readers of his correspondence from the army and from the older seats of empire in Asia and in Europe. Carleton's literary photographs were the means of moving many a young and adventurous couple from their homes in the East to the frontier, and of firing the ambition of many a lad and lass to seek their fortune west of the Mississippi. Since California was settled and the Pacific Coast occupied even at scattered points, our frontiers, strange as it may seem, have not been at the eastern or western ends, but on the middle of the country.
After this campaign of correspondence, Carleton returned home and wrote that little book which has been so widely read, both in the East and in the West, entitled "The Seat of Empire." It was published in 1870 by Fields & Co., of Boston. It had eight pages of introduction, with a map of the territory yet to be settled. It was a volume of 232 pages, 16mo, and was illustrated. For many years afterwards, amid the hundreds of letters received from grateful readers of his books, none seemed to give Carleton more pleasure than those from readers who had become settlers. This little book had indeed come to many as a revelation of the promised land. The contagion reached even to Mrs. Coffin's brothers, one of whom, with a nephew of Carleton, became a pioneer farmer in the Red River Valley in Dakota.
Another pathfinder, a literary as well as military pioneer in opening this noble region to civilization, was the warm friend of Carleton and of the writer, General Henry B. Carrington, of the United States regular army, and author of that standard authority, "Battles of the American Revolution." During the Civil War, General Carrington had been stationed in Indiana, where he was the potent agent in spoiling the treasonable schemes of the Knights of the Golden Circle, and in nobly seconding Governor Morton in holding the State true to the Union. The war over, he served on the Western plains until 1868, and then wrote "Absaraka, the Home of the Crows," which was a score of years afterwards republished under the title of "Absaraka, the Land of Massacre." General Carrington was afterwards one of the active members of Shawmut Church. With his fine scholarly and literary tastes, he made a delightful companion.
Any well-told narrative of the exploration, conquest, and civilization of a country, with a history which has helped to make the pageant and procession of human achievement so rich, is, when fully known, of thrilling interest. How grand is the story of the Aryans in India, of the first historic invaders of Japan, of the Roman advance into northern Europe, of the making of Africa and of western America in our own times! Even the culture-epoch of the North American Indians, as written by Longfellow, in his "Song of Hiawatha," is as fascinating as a fairy tale.
Carleton, believing himself and his country to be "in the foremost files of time" and "the heirs of all the ages," came, saw, and wrote of our empire in the Northwest, with an intoxication of delight. Furthermore, he believed that those who came after him would see vastly more of this part of the earth replenished and subdued. Yet the conquest for which he longed was not to be with blood. His hope and his purpose were intensely ethical and spiritual. His vision was of the triumph of peace, law, order, religion. He urged emigrants looking beyond the Mississippi, or the Rockies, to go in groups, and take with them "the moral atmosphere of their old homes." He advocated the opening of a school the first week and a Sunday school the first Sunday following the arrival of such a colony at its destination. Even a bare, new home, cramped and poor, he suggested, might be to them the type of a better one in more prosperous years, and of the Home beyond, so that, from the beginning, "on Sabbath morning, swelling upward on the air, sweeter than the lay of the lark among the flowers, will ascend the songs of the Sunday school established in their new home. Looking forward with ardent hope of the earthly prosperous years, they would look still beyond to the heavenly, and sing:
