THE discovery of the gold mines of California was a signal for enterprise, daring, and achievement, not only to our commerce and the thrift of our shifting millions of uneasy settlers, but also to the literature and landscape-art of the United States. "To the kingdom of the west wind" hied artist and author alike; and the epic of the settlement of California, of the scaling of the Rocky Mountains, of the glory of the Columbia River, and the stupendous horrors of the Yellowstone was pictured on the canvas of the artist. Taylor and Scott conquered the Pacific slope; Fremont pointed out the pathway over the swelling ranges of the Sierras; and our painters revealed to us the matchless splendor of a scenery which shall arouse increasing astonishment and reverential awe and rapture in the hearts of generations yet to be. In the gratitude we owe to these landscape-painters who dared, discovered, and delineated for us the scenery of which we were hitherto the ignorant possessors, criticism is almost left in abeyance, for the service done the people has been a double one—in leading them to the observation of paintings, and informing them of the attractions of a little known possession. If the art of these paintings of our Western scenery had been in all respects equal to the subject, the country would have been rich indeed. Among the artist explorers to whom we are most indebted, Messrs. Bierstadt, Hill, and Moran are the most famous. The former, by his great composition entitled the "Rocky Mountains," threw the people into an ecstasy of delight, which at this time it is difficult to understand, and bounded at one step to celebrity.

Albert Bierstadt is a native of Düsseldorf, but came to this country in infancy. Subsequently he studied at Düsseldorf and Rome. On returning to America, he accompanied the exploring expedition of General Lander that went over the plains in 1858. Fitz Hugh Ludlow, the well-known littérateur, was associated with him in a subsequent trip, and several graphic articles in which he afterward described the journey undoubtedly helped to bring Mr. Bierstadt into notice.

The "Rocky Mountains" is not the representation of an actual scene, but a typical composition, and, thus regarded, is an interesting work, although it seems to us somewhat too theatrical, and scarcely true in some of the details. Local truth is desirable in topographical art, although of quite secondary importance in compositions of a more ideal character. Since then this artist has executed a number of similarly ambitious paintings of our Western scenery, including a colossal painting of the gorge of the Yosemite Valley. All of them are characterized by boldness of treatment, but sometimes they are crude in color and out of tone. Of these we prefer, as least sensational and most artistically correct, the painting of a storm on Mount Rosalie. Bierstadt's smaller California scenes are generally more valuable than his large ones for artistic quality: one of the best compositions we have seen from his easel is a war sketch representing Federal sharp-shooters on the crest of a hill behind some trees. This is an excellent piece of work, fresh, original, and quite free from the Düsseldorf taint; and confirms us in the opinion that Mr. Bierstadt is naturally an artist of great ability and large resources, and might easily have maintained a reputation as such if he had not grafted on the sensationalism of Düsseldorf a greater ambition for notoriety and money than for success in pure art.

Some of the qualities we have learned to look for in vain in the canvases of Bierstadt we find emphasized in the paintings of Thomas Hill, who succeeded him as court painter to the monarch of the Rocky Mountains. Hill began life as a coach-painter at Taunton, Massachusetts. After deciding on a professional art career, he visited Europe, and benefited by observation in foreign studios, especially of France, although his style is essentially his own. His method of using pigments is sometimes open to the accusation of hardness; there is too often a lack of juiciness—a dryness that seems to remind us of paint rather than atmosphere, which may be owing to the fact, as I have been informed, that he uses little or no oil in going over a painting the second time. But Mr. Hill is a good colorist, bold and massive in his effects, and a very careful, conscientious student of nature. He has been happy in the rendering of wood interiors, as, for example, bits from the Forest of Fontainebleau. One of his most remarkable New England landscapes represents the avalanche in the Notch of the White Mountains, which was attended with such disastrous results to the dwellers in the valley. But Mr. Hill will be identified in future with California, where he has become a resident, and has devoted his energies to painting some of the magnificent scenery of that marvellous region, where the roar of the whirlwind and the roll of the thunder reverberate like the tread of the countless millions who evermore march to the westward. As he sat on the edge of the precipice, the forerunner of coming ages, and painted the sublime, solitary depths of the Yosemite, did the artist realize that with every stroke of the brush he was aiding the advance guard of civilization, and driving away the desolation which gave additional grandeur to one of the most extraordinary spots on the planet? In his great painting of the Yosemite he seems to have been inspired by a reverential spirit; he has taken no liberties with his subject, but has endeavored with admirable art to convey a correct impression of the scene; and the work may be justly ranked with the best examples of the American school of landscape-painting.

The first fever of the California rush had subsided when the uneasy explorer again stirred the enthusiasm of adventurous artists by thrilling descriptions of the Yellowstone River, its Tartarean gorges, and the lurid splendor of its sulphurous cliffs and steaming geysers. Once more the landscape artist of the country was moved to go forth and make known to us those unrevealed wonders; and Thomas Moran, "taking his life in his hands," in the language of religious cant, aspired to capture the bouquet, the first bloom, from this newly-opened draught of inspiration. We all know the result. Who has not seen his splendid painting of the "Gorge of the Yellowstone," now in the Capitol at Washington? Granting the fitness of the subject for art, it can be frankly conceded that this is one of the best paintings of the sort yet produced. The vivid local colors of the rocks, which there is no reason to doubt have been faithfully rendered—for Mr. Moran is a careful and indefatigable student of certain phases of nature—appear, however, to give such works a sensational effect.

This seems to us to be the most valuable of the numerous paintings of Western subjects produced by this artist. It would be a mistake, however, to judge him wholly by the more ambitious compositions suggested by tropical or Western scenery. Some of his ideal paintings are very clever, and show us an ardent student of nature, and a mind inspired by a fervid imagination. But while conceding thus much to the talents of this artist—who belongs to an artistic family, two of his brothers being also well-known painters, one in marine, the other in cattle painting—we can not accord him great original powers. He has studied the technique of his calling most carefully, and has bestowed great attention to the methods of several celebrated artists; but we are too often conscious, in looking at his works, that his style has leaned upon that of certain favorite painters. There is great cleverness, but little genius, apparent in the landscapes of Mr. Moran, for the imitative faculty has been too much for him.
