Many of these Dime Library pamphlets are also biographical. The narratives of this type dealing with celebrated western characters embrace “Kit Carson, Jr., the Crack Shot of the West” (No. 3), by Major Hall; “Joaquin, the Saddle King” (No. 154), by Badger; “Wild Bill” (No. 154), by Ingraham; “Big Foot Wallace” (No. 204), by Major Hall; and “The Lasso King’s League” (No. 653), and “The Cowboy Clan” (No. 658), by Ingraham. The last two named deal with Buck Taylor of Texas. Several of this series were written by Cody, and still others relate to him. Among these are “Buffalo Bill’s Secret Trail” (No. 682), by Major Burr; and “Buffalo Bill’s Body Guard” (No. 727), by Ingraham. Included also in this department of the collection are a number of Aiken’s stories of New York City life. Some of these titles are “The Wolves of New York” (No. 161); “The Phantom Hand, or the Heiress of Fifth Avenue” (No. 72); and “The Wall Street Blood, or, Tick, Tick, the Telegraph Girl.” [Illustration: TYPE J] [Illustration: TYPE L] Following the imposing array just described there come, in the exhibition, representatives of seven exceedingly rare groups of Beadle publications. Of “Beadle’s Dime Fiction Library,” published in 1864 and 1865, only five examples are present. The “Library of Choice Fiction,” also published in 1864, is represented only by “The Maiden Martyr,” which deals with the New England witchcraft horror. “Beadle’s 15 cent Novels” series, which appeared in 1861, has a New York history specimen in the shape of “The Maid of Esopus, or, The Trials and Triumphs of the Revolution.” The “American Novels” series contains nine titles. It appeared from 1865 to 1867, and the little books bear the imprint of Irwin P. Beadle, who was a brother of Erastus. No. 7 of this type is “Fort Stanwix; a Tale of the Mohawk in 1777,” by Hamilton Myers. Next in succession are “Frank Starr’s American Novels,” of which there are but four, published from 1870 to 1872, and they, in turn, are followed by four specimens of the “Frank Starr’s Fifteen Cent Illustrated Novels,” which appeared in 1870 and 1871. Last of all, in this group of rarities, are six copies of the “Boys’ Books of Romance and Adventure.” These, which are perhaps the most uncommon and important of the Beadle issues, are attractive octavos, on colored covers. No. 1 of the series (which the Library shows), is Robinson Crusoe, but all the others deal with famous personages and events in American history. Some of the books contain several such narratives, among them being stories of Marion and his men, of Daniel Morgan, of Tecumseh, Moody, Simon Girty, and other historic characters of pioneer times. This series of publications was edited by Edward S. Ellis, and, like several other groups with which it is associated in the exhibition, has hitherto escaped the knowledge of bibliographers.
