These three numbers of Mr. Clark's writings contain a series of essays and sketches, under the rather fantastic title of Ollapodiana, which were originally published in the Knickerbocker. They are written in a free and flowing style, merry and sad by turns, now in the sunshine and now in the shade, but always with an under-current of deep feeling, in which there are no impurities. Occasionally, poems, sometimes original and at others selected, are introduced, showing the taste and graceful power of the author, and the habitual tendency of his mind toward the beautiful. Indeed, we think Mr. Clark a better poet than prose writer. The whole tone of his mind is highly poetical, and his thoughts continually flow into rhythm, if not into rhyme.... All Mr. Clark's friends (and few men have had more or warmer ones) will welcome this volume, as a mirror of his mind, of his quaintness, his humor, his pathos, his easy, careless manner, his disregard of conventionalities, and, above all, of his gentle, humane, and generous heart.
