Philadelphia is the fact, that by this plan the Managers are merely the agents who collect the means which are necessary to promote and foster the Arts of Design in our rapidly progressing country, while the prize-holders themselves actually become the persons who make the disbursements. Thus giving to the people at large the means to exercise a public and universal taste in the expenditure of a large sum--the aggregate of small contributions--large as the liberality of our countrymen, by their generous subscription, may assist us in accumulating." * * * * * The _Western-Art Union_ of Cincinnati has lately published a large and excellent engraving by Booth, of _the Trapper's Last Shot_, and for the coming year, it will give in the same style, _The Committee of Congress Drafting the Declaration of Independence_, from a painting by Rothermel--Mr. Jefferson represented reading the Declaration to the other members of the committee before it was reported to the Congress. For prizes of the next distribution the Union will have a bust of Washington, and one of Franklin, in marble, by Powers, and a beautiful medallion in relief by Palmer, and two pictures are engaged or purchased from Whittridge, two from Rothermel, two from McConkey, one from Read, one from Mrs. Spencer, one from Ranney, and one from Terry, besides others from Sontag, Duncanson, Eaton, and Griswold, and other western painters. * * * * * Mr. HEALY has finished his large picture of _Daniel Webster replying to Robert Y. Hayne, in the Senate of the United States_, and it has been some time on exhibition at the rooms of the National Academy of Design. The canvas is twenty-six feet in length by fifteen in breadth, and embraces one hundred and thirty figures. Many persons not senators are introduced, and it is difficult to conceive a reason for this, in the cases of several of them, who were not then, if they were ever, at Washington. The picture has good points, but on the whole we believe it is admitted to be a failure--so far as the fit presentation of the illustrious orator is concerned, a most complete and melancholy failure. Engravings of it however, if well executed, may perhaps compete with Messrs. Anthony's immense piece of mezzotint, studded with copies of Daguerreotypes, which has been published under the title of Mr. Clay's last Appearance in the Senate. * * * * *
