Two men attempted to duplicate Church's success, but with very indifferent result. They were Albert Bierstadt and Thomas Moran. The former sought the Rocky Mountains for his subjects; the latter, the Yosemite and the Yellowstone; but neither of them succeeded in transferring to canvas more than a pale and unconvincing presentment of the wonders of those regions.

Durand also had a disciple, more famous than Cole's, in Frederick Kensett, the best known of the so-called Hudson River school. He was a close follower of Durand in believing that nature should be literally rendered, but he missed the truth of the older man by working in his studio from drawings and sketches, instead of in the open air direct from his subject. So he got into the habit of painting all shadows a transparent brown, and of making his rocks and trees brilliant by touching in high-lights where he thought they ought to be instead of where they actually should have been. He surpassed Durand, however, in his range of subject, for all hours and seasons had their charm for him, while Durand was really at home only in the full light of a summer day.

On this foundation a loftier structure was soon built and the builders were George Inness, Alexander Wyant and Homer D. Martin. Inness was the oldest of the three, having been born in 1825, and was contemporary with some of the most arbitrary and hide-bound of the nature copyists. But he felt the weakness of the method and himself attained a much fuller and completer art. He seems to have dabbled with paint and brushes from his youth, but had little regular instruction, studying, for the most part, from prints of old pictures, and finally, in 1847, getting a chance to see the original when a friend offered to send him to Europe. He passed fifteen months in Rome, and afterwards a year at Paris.

A long period of assimilation followed, in which he developed a theory of art and struggled to transfer it to canvas. It was a sound and true theory, and is worth setting down here for its own sake. "The purpose of the painter," Inness held, "is to reproduce in other minds the impression which a scene had made upon him. A work of art does not appeal to the intellect or to the moral sense. Its aim is not to instruct, not to edify, but to awaken an emotion. It must be a single emotion, if the work has unity, as every such work should have, and the true beauty of the work consists in the beauty of the sentiment or emotion which it inspires. Its real greatness consists in the quality and force of this emotion."

To the very last, Inness's work was changing and developing to fit this theory. He steadily gained mastery of tone and breadth of handling, of true harmony, and it is his crowning merit that he does to some extent succeed in "reproducing in other minds the impression which the scene made upon him."

Alexander H. Wyant was a pupil of Inness, journeying from the little Ohio town where he was born to see him and to ask for advice and aid, which Inness freely gave. Wyant's boyhood had been the American artist's usual one—an early fondness for drawing, a little practice, and then setting up as a painter. In 1873 he joined an expedition to Arizona and New Mexico. The hardships which he endured resulted in a stroke of paralysis and he was never again able to use his right hand. With an inspiring patience, he set to work to learn to use his left hand, and grew to be more skillful with it than he had been with his right.

But even at his best, Wyant's appeal is more limited than Inness's. He learned to paint a typical picture, a glimpse of rolling country seen between the trunks of tall and slender birches or maples, and was content to paint variations of it over and over. That he sometimes did it superbly cannot be denied, and he possessed a certain delicate refinement, an ability to throw upon his pictures the silvery shimmer of summer sunshine, in which no other American artist has ever surpassed him.

The third, and in some respects the most interesting member of the group is Homer D. Martin. Born in Albany in 1838, he turned naturally to painting and began to produce pictures after only two weeks' instruction. At first, he was a disciple of Kensett, with brown shadows and artificial high-lights, but study of nature soon cured these mannerisms, and he grew steadily in skill and power, until he succeeded in imparting to his pictures the deep, grave and sobering sentiment, which is the keynote of his work. His coast views, with their swirl and almost audible thunder of billow, are considered his crowning achievements.

This culmination of the Hudson River school brings us fairly to our own times and to the work of men still living, for the period just preceding and following the Civil War was marked by no new impulse in American art and by no work which demands attention. But in the early seventies, there were a number of Americans studying at home or in Europe who have since won a wide reputation for inspiring achievement.

Foremost among these is Elihu Vedder, born in New York City in 1836, and following, in his manhood, the manifest bent of his childish years. He went to Paris before he was of age, and from there to Rome, where he spent five years. The five succeeding years were spent in America, and finally, in 1866, he settled in Rome and has since made it his home. He represents a revival of the classical quality of Raphæl or Michæl Angelo, though he belongs to no school, and his work has from the very first possessed a distinct originality. He has held to the old simplicity, which minimized detail and exalted the subject. General recognition came to him in 1884, when he published his illustrations to the Rubaiyat of Omar Khayyam—the most sympathetic and beautiful pictorial comment which has ever been given any book of poetry. Since then he has executed much decorative work of a high order, though the mastery in this branch of the art is held by another.
