The development of inventions during this period revolutionized the world's progress. Cities in various parts of the country had begun to communicate with each other by electricity, when Thoreau was living at Walden; when Emerson was writing the second series of his Essays; Longfellow, his lines about cares "folding their tents like the Arabs and as silently stealing away"; Lowell, his verses To the Dandelion; and Holmes, his complaint that his humor was diminishing his practice. By the time that Longfellow had finished The Courtship of Miles Standish, and Holmes The Autocrat of the Breakfast Table, messages had been cabled across the Atlantic. A comparison with an event of the preceding period will show the importance of this method of communication. The treaty of peace to end the last war with England was signed in Belgium, December 24, 1814. On January 8, 1815, the bloody battle of New Orleans was fought. News of this fight did not reach Washington until February 4. A week later information of the treaty of peace was received at New York. A new process of welding the world together had begun, and this welding was further strengthened by the invention of that modern miracle, the telephone, in 1876.

The result of the battle between the ironclads, the Monitor and the Merrimac (1862), led to a change in the navies of the entire world. Alaska was bought in 1867, and added an area more than two thirds as large as the United States comprised in 1783. The improvement and extension of education, the interest in social reform, the beginning of the decline of the "let alone doctrine," the shortening of the hours of labor, and the consequent increase in time for self-improvement,—are all especially important steps of progress in this period.

Authors could no longer complain of small audiences. At the outbreak of the Civil War the United States had a population of thirty-one millions, while the combined population of Great Britain and Ireland was then only twenty-nine millions. Before Holmes passed away in 1894 the population of 1860 had doubled. The passage of an international copyright law in 1891 at last freed American authors from the necessity of competing with pirated editions of foreign works.

SUMMARY

The great mid-nineteenth century group of New England writers included
Emerson, Thoreau, Hawthorne, who were often called the Concord group, and
Harriet Beecher Stowe, Daniel Webster, Longfellow, Whittier, Lowell,
Holmes, and the historians, Prescott, Motley, and Parkman.

The causes of this great literary awakening were in some measure akin to those which produced the Elizabethan age,—a "re-formation" of religious opinion and a renaissance, seen in a broader culture which did not neglect poetry, music, art, and the observation of beautiful things.

The philosophy known as transcendentalism left its impress on much of the work of this age. The transcendentalists believed that human mind could "transcend" or pass beyond experience and form a conclusion which was not based on the world of sense. They were intense idealists and individualists, who despised imitation and repetition, who were full of the ecstasy of discoveries in a glorious new world, who entered into a new companionship with nature, and who voiced in ways as different as The Dial and Brook Farm their desire for an opportunity to live in all the faculties of the soul.

The fact that the thought of the age was specially modified by the question of slavery is shown in Webster's orations, Harriet Beecher Stowe's Uncle Tom's Cabin, the poetry of Whittier and Lowell, and to a less degree in the work of Emerson, Thoreau, and Longfellow.

We have found that Emerson's aim, shown in his Essays and all his prose work, is the moral development of the individual, the acquisition of self-reliance, character, spirituality. Some of his nature poetry ranks with the best produced in America. Thoreau, the poet-naturalist, shows how to find enchantment in the world of nature. Nathaniel Hawthorne, one of the great romance writers of the world, has given the Puritan almost as great a place in literature as in history. In his short stories and romances, this great artist paints little except the trial and moral development of human souls in a world where the Ten Commandments are supreme.

Longfellow taught the English-speaking world to love simple poetry. He mastered the difficult art of making the commonplace seem attractive and of speaking to the great common heart. His ability to tell in verse stories like Evangeline and Hiawatha remains unsurpassed among our singers. Whittier was the great antislavery poet of the North. Like Longfellow, he spoke simply but more intensely to that overwhelming majority whose lives stand most in need of poetry. His Snow-Bound makes us feel the moral greatness of simple New England life. The versatile Lowell has written exquisite nature poetry in his lyrics and Vision of Sir Launfal and The Biglow Papers. He has produced America's best humorous verse in The Biglow Papers and A Fable for Critics. He is a great critic, and his prose criticism in Among My Books and the related volumes is stimulating and interesting. His political prose, of which the best specimen is Democracy, is remarkable for its high ideals. Holmes is especially distinguished for his humor in such poems as The Deacon's Masterpiece, or the Wonderful One-Hoss Shay and for the pleasant philosophy and humor in such artistic prose as The Autocrat of the Breakfast Table. He is the only member of this group who often wrote merely to entertain, but his Chambered Nautilus shows that he also had a more serious aim.
