 A Perfect Bread Slicing Machine 

 for the Commissariat 



ANEW bread-slicing machine re- 

 cently devised by two Washing- 

 ton men — W. H. Garlock and W. J. 

 Stubbe, of Seattle, slices an entire 

 loaf at one operation without crush- 

 ing, tearing, or breaking the slices. 



A number of knives, supported in 

 two frames, are operated vertically 

 and simultaneously but in opposite 

 directions. W T hen one set of knives 

 is traveling up, the other set is travel- 

 ing down. By this arrangement 

 the friction in the slicing operation 

 is counteracted and the softest and 

 hardest baked loaf can be sliced 

 equally well. 



The workman operates the knives by 

 pressing on a treadle. A second operator 

 at the rear or side of the machine then 

 moves a lever that operates a mechanism 

 that ejects the slices of bread. Meanwhile 

 a release of pressure on the treadle permits 

 a weight to restore the carriage of the 

 machine to its initial position, and a plate 

 is automatically drawn from under the 

 slices, allowing them to roll into a recep- 

 tacle beneath. When delicate cakes are 

 cut the slices are lifted

A Leopard Ship of the Sea — Even the 

 Masts Are Spotted 



FOOLING the enemy is a remunerative 

 and interesting pastime with the Allies. 

 They have their camouflage on land; now 

 comes the camouflage of the sea. A ship is 

 painted with spots which fade out into 

 a glittering and shimmering haze in the 

 sunlight. A submarine commander one or 

 two miles distant might look straight at 

 the ship and never see her. 



The spots are of light gray and navy 



blue, which, even on a sunless day 



blend with the waves of the ocean. 



The indistinct outline which this 



gives makes the ship a poor target.

Fat People Are Unpatriotic. Give 

 Up Your Fat to the Nation 



ACCORDING to statistics 

 compiled by the Life In- 

 surance companies, there are, between 

 the ages of thirty-five and fifty-five years, 

 a vast number of people who are hoarding 

 and accumulating fat enough to supply 

 energy equivalent to that of 690,355,533 

 loaves of bread, enough to supply an army 

 of 3,000,000 men for sixty days. A man 

 who is forty pounds overweight is carrying 

 on his body the equivalent in fuel value 

 of 135 one-pound loaves of bread. 



If the guilty ones would cease this 

 accumulation (which they are willing 

 enough to do) it would release much-needed 

 fuel foods, such as wheat, corn, oats, 

 barley and rye. There are two ways of 

 surrendering this fat. One is by judicious 

 exercise and the other is by substituting 

 other foods for the fat-building kinds.
