It is useless to deny that, extravagant as some of the works of the contemporary impressionists appear to many, they undoubtedly present a keen appreciation of aërial chromatic effects, and for this reason are worthy of careful attention. That they are not carried nearer to completion, however, indicates a consciousness on the part of the artist that he is as yet unable to harmonize the objective and subjective, the material and the spiritual phases of art. A perfect work of art combines the two; but, alas! such achievements are as yet rare, although that is the ideal which the artist should keep in view. The artist who gives us what is called a finished painting is so far right. He represents what appears to the material eye. In proportion as he combines with this a suggestion of the intellectual impression also made on his mental vision, he approaches the ideal in art execution. On the other hand, the artist who is impatient of details, and deals wholly with a broad, and sometimes, we regret to say, dauby and slovenly interpretation of nature, is yet so far right, because he is endeavoring to interpret the wholly imaginative and intellectual side of art. When to this bias he adds the balance of power which enables him to give something of the other phase of art, he in turn approaches the ideal aim of art. Turner was an impressionist; so was Corot; so, to go farther back, was Velasquez; so, also, are the Japanese. But these artists, especially Turner and Velasquez, had the supreme faculty of uniting the two opposite poles in art in their best works, and hence the commanding position which they hold, and always will hold, in the art world. [Illustration: SOUTHAMPTON, LONG ISLAND.--[C. H. MILLER.]] So far as can be ascertained, it is to the late William M. Hunt that we must ascribe the initiation of the third period in our pictorial art, and perhaps, in a secondary manner, the general impulse toward foreign styles now modifying the arts of design in this country. When Mr. Hunt went to Düsseldorf to study, in 1846, he did no more than many of our artists had already done. But when, dissatisfied with the conventionalism of that school, he turned his steps to Paris, and became a pupil of Couture, and was one of the first to discover, to admire, and to emulate the art methods of Millet, then, unconsciously, he became a power, destined by his somewhat narrow but intense personality to influence the destinies of our art--especially by returning to Boston, a city easily brought under the magnetism of a strong individuality, and more ready than any other city in the land to surrender the guidance of its opinions to those whom it condescends to admire.
