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 mouth in the world — 

 a model for a dentists' exhibition 



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.
