"In hope of renovating the energies of a shattered constitution," we are told, Flagg started in the early part of June, 1836, on a journey to what was then known as the Far West. Taking a steamboat at Louisville, he went to St. Louis by way of the Ohio and the Mississippi, and after a brief delay ascended the latter to the mouth of the Illinois, and thence on to Peoria. Prevented by low water from proceeding farther, he returned by the same route to St. Louis, whence after three weeks' stay, spent either in the sick chamber or in making short trips about the city and its environs, the traveller crossed the Mississippi and struck out on horseback across the Illinois prairies, visiting Edwardsville, Alton, Carlinsville, Hillsborough, Carlisle, Lebanon, Belleville, and the American Bottoms. In July, after recrossing the Mississippi, he visited in like manner St. Charles, Missouri, by way of Bellefontaine and Florissant; crossed the Mississippi near Portage des Sioux, and passed through the Illinois towns of Grafton, Carrollton, Manchester, Jacksonville, Springfield, across Grand Prairie to Shelbyville, Mount Vernon, Pinkneyville, and Chester, and returned to St. Louis by way of the old French settlements of Kaskaskia, Prairie du Rocher, and Cahokia. During this journey Flagg wrote for the Louisville _Journal_, as already stated, a series of letters describing the country through which he travelled. Hastily thrown together from the pages of his note book, this correspondence appeared anonymously under the title, "Sketches of a Traveller." They were, however, soon attributed to Flagg, and two years later were collected by the author and published in two small volumes by Harper and Brothers (New York, 1838), as _The Far West_. These volumes are in many respects the best description of the Middle West that had appeared up to the time they were written. Roughly following the journals of Michaux, Harris, and Cuming by forty, thirty, and twenty years respectively, Flagg skillfully shows the remarkable growth and development of the Western country. His descriptions of the Ohio, Mississippi, and Illinois rivers are still among the best in print, particularly from the artistic standpoint. His account of the steamboat traffic is valuable for the history of navigation on the Western rivers, and shows vividly the obstacles which still confronted merchants of that time. Chapters xi, xii, and xiii, dealing with St. Louis and its immediate vicinity, are the most detailed in our series, while the descriptions of St. Charles and the Illinois towns through which Flagg passed, are excellent.
