41, The Happy Moment—105, The Recovery—Carl Hubner. These, no doubt, are _popular_ works—as works of certain classes always will be. We have heard much said in praise of them. They are beautifully, exquisitely painted—especially the “Happy Moment,” in which the color and execution are admirable. But in _sentiment_, or any of the _ideal_ qualities of such subjects, they are lamentably deficient. Like nearly all the German painters, Carl Hubner possesses much greater _executive_ than _imaginative_ powers—he is more of a _mechanic_ than an _artist_. He gratifies the _eye_ at the expense of the _mind_. Surely rustic love is suggestive of something more than any thing hinted at in the “Happy Moment.” “The Recovery” is composed of the usual conventional material of such subjects—a simpering physician, with a nice diamond ring on his finger, friends, with the old, upturned eyes and clasped hands, are mechanically put together—all standing or sitting evidently on purpose to be painted. In landscape, the best works in the collection are Nos. 35 and 136, by Diday, a Geneva artist—a Moonlight, No. 46, B. Stange, and No. 78, a Roman Aqueduct at Alcala, with caravans of muleteers, F. Bossuet. The two first are grand and imposing representations of scenery in the High Alps—in color they are deep and rich in tone. The Moonlight, by Stange, is the best we have ever seen. The tremulous luminousness of the moonshine is rendered with matchless truth. The Roman Aqueduct, by Bossuet, is, beyond question, the finest landscape in the collection. Sunlight, local color, and texture were never painted with greater truth than in this splendid production. Light and heat pervade every nook and corner of the picture, from the dry, dusty foreground, off to the distant mountains which close the scene. The work furnishes a grand example of artistic execution and detail. No 52—Lake George—Russel Smith—is a beautiful piece of open daylight effect, possessing great truth. A Scene on the North River—Paul Weber—possesses much merit. The color is fresh and natural, and the sky is the best we have seen by this artist.
