We have more than once been pained by hearing the words 'humbug,' 'great advertizing establishment,' etc., applied to the New York Fair, as well as to fairs in general. Now, nothing could be more unjust than the first term; and as to the latter, we have only to say that, if human nature were perfect, fairs would be unnecessary, and a subscription all that any just enterprise would require for success. Beneficence on a large scale, however, requires the money of the selfishly munificent as well as of the purely generous, and fairs not only procure purchasers for such articles as givers can spare with the least detriment to themselves, but also make known the names and quality of wares of various dealers. The man who might have _subscribed_ ten dollars, is content to pay one hundred for an object contributed from the time and labor of some individual devoid of other commodities. If the wares in question become more widely known, and benefit hence accrue to the giver, the consequence is surely a legitimate one, and even a fortunate condition of the facts, as increasing the size of the fund received. They who give simply with the idea of doing good, will doubtless receive their appropriate reward; and they who give with mixed motives know well that the alleviation purchased by their contribution will be as welcome to the sick soldier as that procured by the more unselfish donation. Our admiration for the individual may vary with our knowledge of his springs of action, but if love of self can be made to minister to the wants of the suffering, all the better, especially as no man can (without certain knowledge) dare to sit in judgment upon the motives of his fellow men. Each department has done well, and none better than that devoted to painting, statuary, engraving, and photography. Large sums have been realized upon the pictures presented by the artists--generous gifts indeed from men (and women) not usually overburdened with this world's gear. M. Knoedler, of the Art Committee, merits the especial gratitude of the community, not only for the generous but unobtrusive zeal displayed by him, but also for large contributions in engravings and photographs. The gift department of the picture gallery comprised works from all our best-known names, as well as from some hitherto unknown. The artists' albums were also a special feature in this domain. Judging merely as outsiders (having owned no certificate of subscription), we thought the anti-raffling rule might either have been suspended in their favor, or should certainly have been enforced upon the first day, before the burden of so many subscriptions had fallen upon the shoulders of the energetic artists having them in charge.
