The ingenious patent which has been got up for use in prohibition states.
Some curious patents are taken out at the Patent Office. One last week—“cover for liquor flask”—would never be fully appreciated by its title. It is a design of a book, about two and a half inches thick. At the bottom end of the book is an opening for the insertion of the flask, the opening being afterwards neatly closet with a sprint, the surface of which is marbleized lie a book end of leaves. At the top all seems correct and regular, but the pressure of the thumb throws open a circular hole at the same time raise the neck of the hitherto hidden vessel about two inches within easy range of the mouth.
