When you can't find it any where else look into this
 AD, PHi. Herndon relates the following: ``Lincoln had always on the top of our desk a bundle of papers into which he slipped anything he wished to keepPage 425
and afterwards refer to. It was a receptacle of general information. Some years ago, on removing the furniture from the office, I took down the bundle and blew from the top the liberal coat of dust that had accumulated thereon. Immediately underneath the string was a slip bearing this endorsement, in his hand: ``When you can't find it anywhere else, look in [sic] this.'' (Herndon, II, 315n.).
