The Free Gallery of this Institution, located at No. 210 Chestnut Street, has doubtless had a most beneficial influence in disseminating a taste for Art, and preparing the public for its just appreciation. The walls of this gallery have been constantly supplied with much-admired pictures, and a crowd of visiters are always in attendance. We hope hereafter to find much pleasure in referring to the new pictures exhibited in this gallery. The effects which are dependent upon the success of the Art Union, are shown by the great impetus which has been given of late years to many extremely varied branches of manufactures and commerce by a judicious encouragement of the Arts of Design. It has been found, more particularly in Europe, that numerous classes, hitherto considered as inoperative and useless, have been supplied with employment, and entire districts revivified, as it were, by the establishment of certain manufactures, whose excellence depended mainly upon the skill of the artist. The surest means of effecting this result, is to create a public taste, and not merely comply with it as it exists at large; and it may be brought about by offering rewards for the best designs, by the publication of the best specimens of Art at cheap prices, by the erection of free galleries of painting, and chiefly by the encouragement of Art Unions. With such objects in view, and such results to achieve, the multiplication of these institutions in our country must be regarded as a cheering indication of the true progress of the age, and the precursor of a widely diffused love of the Beautiful in Art, which cannot but tend to the general improvement of the useful arts. All such results must be effected by our citizens at large, for we cannot expect legislative aid, and hence it is that we feel the necessity of impressing upon the public attention the operation of the Art Unions, as the great popular plan for fostering talent, infusing a love for the beautiful in Nature and Art, and cultivating those studies which invariably mark national progress in civilization, refinement and general happiness. * * * * * NEW JERSEY ART UNION.—We announce with great pleasure that an association of the friends of art in Newark have drawn up the programme of an Art Union, and made a stirring appeal to the citizens of the State for encouragement and co-operation. A free gallery will be opened immediately at Newark, and pictures purchased for distribution among subscribers. For the present, no engraving will be contracted for, and this heavy item being dispensed with, will increase the sum to be appropriated for the purchase of paintings. We most cordially wish the enterprise success, and trust that our New Jersey friends will be prompt in sending their names to Thomas H. Stephens, the Corresponding Secretary, at Newark. * * * * *
