When the vast multitude had convened, the exercises were commenced by the Rev. S.R. Ward, who addressed the throne of grace, after which, Mr. Frederick Douglass delivered an oration, in a style of eloquence which only Mr. Douglass himself can equal, followed by a song from the Geneva choir, and music by Barring's band. Rev. H.H. Garnet, editor of "The National Watchman," next spake, and with marked effect, followed by Messrs. Ward and Douglass; after which, the assemblage formed a procession, and marching to the Canandaigua Hotel, partook of a sumptuous dinner, provided by the proprietor of that house. At six P.M., they again assembled on the square, and were most eloquently addressed by both Ward and Garnet; at the close, they repaired to the ladies' fair, where they found everything in a condition which spake well for the enterprise and industry of our colored sisters. Their articles for sale, were of a choice and considerate selection, and such as sold rapidly and at fair prices. When all was pleasantly over, the ladies contributed twenty dollars toward paying the speakers present. A most beautiful ode was composed by a warm and generous friend of the cause, which was sung in the grove, in a spirit which produced a thrilling interest. Gladly would I give the reader the whole composition, but its length makes it objectionable for this place, but should they happen to hear a soul-stirring and sublime ode, commencing with, "Hail! to this day returning; Let all to Heaven aspire," &c., they may know it is the one to which I refer. It was indeed, a glorious day for the colored population generally; and many were the indications of a diminution of that prejudice so prevalent everywhere. Some, who had supposed the colored man so inferior to themselves as to be incapable of making an interesting speech, were convinced of their error, after hearing Messrs. Douglass, Ward and Garnet. Mr. Van Loon was a white clergyman, but a brother indeed; his soul illumined by the pure light of the gospel of peace; his heart full of sympathy for the oppressed; his tongue pleading eloquently for equal rights; and his hands busily engaged in breaking every yoke, resting on the necks of poor humanity. So vigorously, so zealously did he unfold the horrors of the slave system; so truthfully and faithfully did he expose the treachery of northern politicians, and so pathetically did he appeal to the humanity of every professed Christian to speak out boldly for the dumb; to shield, by the holy principles of their religion, the poor, bound, illiterate slave, from Southern cruelty and bondage,--that some of our aristocratic citizens, some of our white savans, repaid his truthful eloquence, by visiting upon him the bitterest maledictions. From the negro, said they, we will accept these statements as true,--from him, they are pertinent and forcible; but when such unpalatable truths are uttered by a white clergyman, we cannot abide, nor will we listen to them!
