I began working four hours a day, now I can work for twelve. I shall lessen the hours, should I find my strength failing. This is my tenth working-day. I have finished seventeen articles, and arranged notes for another. I have used as many of your notes as I could. Maria copies carefully. She lops off to the right and the left with your notes and mine: she corrects, criticizes, abuses, and praises us by turns. Your father's notes, copied from his journal, are valuable—they contain real information; some of the others are humbug and rigmarole; but you have done so well as to surprise us.... I hope that if nothing untoward happens, the Second Volume will be finished in a month, and the Third Volume next winter. [Illustration: LETTER OF JOHN BACHMAN, NOVEMBER 7, 1846, ADDRESSED TO MR. GEORGE OATES, CHARLESTON, SOUTH CAROLINA. From the Jeanes MSS.] About thirty years later, when Victor Audubon's sister-in-law[221] was making a disposition of his literary effects, a bundle of manuscripts was saved and given to Mr. George Bird Grinnell. Included in it were a number of Audubon's letters, which are now reproduced, as well as a considerable section of the printer's copy of _The Viviparous Quadrupeds of North America_, Volume I; this was in various handwritings, including little of Bachman's himself, much of Victor's and of John G. Bell's; a little of this copy also was made by the second Mrs. Bachman and by other and unknown hands, possibly those of one of Bachman's daughters and of his son-in-law, Reverend John Haskell, all of whom are known to have assisted in this labor.
