The second series of Beadle books portraying pioneer conditions and events was called the “Pocket Novels,” which began to appear about 1869 or 1870. These were of the same 12mo size as their predecessors, but the previous uniformity of coloring was abandoned for a more brilliant appearance and each cover was given a multi-colored illustration on a solid background of red, green, blue or brown. Some sixty-four titles of this series are displayed, and almost without exception they deal with historical pioneer conditions, events and personages. Among these books the visitor will find “Mad Anthony’s Scouts,” by Rodman; Whittaker’s “Boone the Hunter” and “Dick Darling” (the pony expressman); “Billy Bowlegs”; and “The Sons of Liberty” and “Mohawk Nat,” by the historian Charles Dunning Clark, who wrote for Beadle under the pen name of W. J. Hamilton. Clark wrote no less than seventeen of the “Pocket Novels” books, nearly all of them dealing with the periods and circumstances of the French-Indian wars in New York, Virginia and Pennsylvania, or with the scenes of the Revolution, phases of national history upon which Clark was a specialist. Many of the “Pocket” series also dealt with the settlement of the Ohio and Mississippi Valleys from 1780 to 1815, and with the Far West from 1849 to 1869. This “Pocket” series is bibliographically known as Type B of the Beadle publications, while the original yellow-backed books belong to Type A. The next two groups--Types D and E--have a common title, the “Boy’s Library of Sport, Story and Adventure,” and are distinguished from one another by the larger size and earlier issuance of the Type D items. They are imperial octavo in size, whereas the Type E publications are ordinary octavos. Both are uncolored, and have their title-pages entirely occupied with bold black-and-white illustrations. The Type D books are somewhat different in various qualities from their predecessors, and were obviously designed to create an interest in foreign countries, peoples and customs as well as in American adventure. A typical item of this class is Harbaugh’s “Snow Shoe Tom, or New York Boys in the Wilderness,” wherein the veteran author (who is still living in Ohio) instructs his readers regarding camp and wilderness life in Maine, in moose-hunting, fishing, trapping, the making of snow-shoes, and self-reliance in the woods. The Type E books are concerned almost wholly with life in the Far West, and with the lives and adventures of celebrated plainsmen. Among these titles are Aiken’s story of the exploits of “Kit Carson”; Joseph Badger’s Autobiography (written under the pen name of Post); and Ingraham’s biography of the celebrated scout called Texas Jack, whose real name was J. B. Omohundro.
