DISCOURSE ON GENIUS. The Richmond Compiler speaks in terms of great praise of a discourse delivered recently in Richmond, before a Young Men's Society, by Joseph Hulbert Nicholas. A number of extracts are also given in the Compiler, as specimens of the performance, from which we take the following notices of two of our fellow-townsmen.--_Boston Courier._ Of Charles Sprague, of Massachusetts, no language can be spoken but that of unqualified praise. Forsaking the modern school of writing, he is contented with being simple and natural. Sublimity, tenderness, wit, elegance, and beneficial satire characterise his muse.--The only complaint I have ever heard made of him is that _he does not write more_. Of Nathaniel Parker Willis, a native of Massachusetts, and a fellow-student with myself at Yale College, I come now to speak. Of him I shall speak familiarly, as of an intimate friend; and impartially and justly, as one who wishes him well. Willis, I venture to pronounce the most remarkable genius our country has yet produced. I do not call him remarkable merely for his unusual precocity of song, but remarkable for the possession of that rare genius, which by any man, young or old, in our land, I do not think has ever been displayed. Nature has done wonderful things for him; but alas! he has thus far done but little for himself. The great pieces he has sometimes given us have cost him but little effort, and he has thrown out his productions, in prose as well as poetry, with a profusion and a variety that seem miraculous; and yet, of all our bards, he has met with the most severe and merciless censures. In some measure he has deserved the treatment. In College he would not condescend to study, and charity only for his high genius enabled him to gain a degree. Besides, he gained his first and best reputation by pieces founded upon scriptural subjects, and he stood committed to the world as a _religious_ man. Many who had never seen aught of him but his productions, and had formed the loftiest estimate of his personal character from the pure tendency of his effusions, were astonished and grieved when introduced to the author.--His head made giddy by the praises of young and old, he forgot himself, and possessing most shrewd good sense, he would talk the reverse. He became fantastic in apparel, as he did likewise in his style of writing; made himself too common, and almost broke a pious father's heart by deserting the altar of that divine Jesus upon whose Bible he had founded the fairest fabric of his fame. My friend, of whom I so sternly speak, is now in Italy; and should these remarks, per chance, ever meet his eye, I beseech him by our past friendship, by our walks "by moon or glittering star-light," through the Eden groves and avenues of
