We give this derivation from memory alone; we cannot even recall the work in which we saw it. If it be the true one, our friend will perceive that in one of his surmises he is not far wrong. It is high time that the birth, parentage and early condition of a particle of our language, which has of late become a word of power, equal in its magic influence to the fabled spells of ancient necromancers, should be settled beyond dispute. Seeing what Caucus now means, it is natural that we should desire to know from what beginnings it has arisen to its present stupendous importance in the ranks of our modern political vocabulary. CRITICAL NOTICES. THE CRAYON MISCELLANY. By the author of the Sketch Book. No. 1. Containing a Tour on the Prairies. Philadelphia: Carey, Lea & Blanchard. 1835. A book from the pen of Washington Irving, is a _morceau_, which will always be eagerly sought after by literary epicures. He is decidedly one of the most popular writers in this country: his sketches of character and scenery, are always true to the life, full of freshness and vigor; and there is usually a clear stream of thought pervading his pages, in fine contrast with the crude and indistinct conceptions of ordinary writers. The volume before us cannot be said indeed to rival some of its predecessors from the same pen, but the cause is not so much in the author as in his subject. In spite of an agreeable and highly descriptive style, the mind becomes wearied with the monotony of a journey through the solitudes of the Western Prairies, and after we have once formed a tolerably distinct idea of a buffalo hunt, and the lasoing of the wild horse, we become tired of the repetition of adventures, which possess so little variety. Considering his materials, however, Mr. Irving has contrived to sustain his narrative with his usual ability. It is true, that most readers will somewhat regret that he did not present more finished portraits of some of the personages who accompanied the expedition. We have quite satisfactory sketches of that "swarthy, meager, braggart" Tonish, and of the "sullen saturnine" half breed Beatte, but we desire to know something more of the wild young Swiss Count, of his travelling companion and mentor, the virtuoso, and of the hardy old hunter, Ryan, a true member of the leather-stocking family. Notwithstanding the famed perspicuity and purity of Mr. Irving's style, he occasionally adopts a form of expression which creates some surprise. We will give one instance, in particular, because the inaccuracy, if we may so term it, is repeated several times in the volume before us:--"The horse, which was fearless as his owner, and like him, had a considerable spice of devil in his composition, and who beside, had been familiar with the game, no sooner came in sight and scent of the buffalo, than he set off _like mad_, bearing the involuntary hunter," &c. &c. &c.
