Second issue, in the stiff brown cloth, the first issue of the book, denoted by the flexible cloth binding, numbered about 500 copies, with the remaining 500 copies of the first edition being bound in a more solid cloth. Although Gallup remarks that "the first copies printed have the word 'mountain' correctly spelled in line 339 (page 41); in later copies the 'a' has dropped out," that point is not the true indication of the issue, but only of the place in the press run of the sheet on which that page was printed. During the printing of the sheet containing that page, the letter "a" worked loose, so that the copies were printed with the "a" correctly placed, out-of-alignment, or missing altogether. Since the sheets were selected for binding at random, the presence of the "a" is indicative only of the printing of that particular sheet, not of the book as a whole. (In this copy, the "a" has dropped out.) Gallup A6b; Hayward 332.
