��Filling Nine Thousand Cans of Beans an Hour
ARMIES may fight with bullets, but . they live on beans. The Civil War was fought on a diet of our dried army beans ; this war is waged with canned beans.
In the photograph below is shown a modern bean- canning factory working at the height of produc- tion. To meet the ex- traordinary demand for beans, labor and time- saving machinery is used exclusively. Al- though located in New Jersey the machine il- lustrated fills up the cans with Boston baked beans and snaps on the covers in practically the same opera- tion. The empty cans are fed to the machine in an endless stream, the cans being held in place by a metal frame. The machine fills the cans at the rate of nine thousand an hour but it can work faster, if needed.

��The Largest Human Mouths in the, World
DR. GREENBAUM, an enterprising young dentist in Cincinnati, eager to help Uncle Sam in demonstrating to the volunteer the necessity of getting his mouth in good shape before enlisting for the front, de- vised what are probably the largest scientifically-cor- rect models of the human mouth in the world.
Each model (and there is an extended series of them) is two feet deep by eighteen inches wide and eight inches tall. The mod- els are hollow and fash- ioned of plaster-of- Paris, held together by gauze.
Ten models of the adult mouth, three of the child's and four panels emphasiz- ing certain phases of disease of the teeth and of decay, comprise the set. The models show the pulpy substance containing blood vessels, nerves, as well as the harder root and bony portions.

��Europe Is Starving for Gasoline
FRANCE, one of our largest automobile and truck buyers, has prohibit- ed the importation of foreign motor vehicles, except for government account sim- ply because of the difficulty of obtaining gasoline. Gas- oline is now selling in " France at about a dollar a gallon. Each automobile owner is allotted a small amount per week. India and Holland have likewise prohibited the importation of motor vehicles for the same reason. Denmark's gasoline situation was so acute that it stopped the driving of passenger cars through the steets. It is said that taxicabs in Berlin have been running on alcohol for two years now.
