226 Miracles Ahead! 



however, tin cans will probably continue to be preferred, 

 since determined rats make short work of cardboard. 



"There are 130 million of us in this country. Right now we 

 are probably feeding 200 million. Before the war is over, we 

 may be feeding three starving people abroad for every Ameri- 

 can. And after the war it will take years to undo the malnu- 

 trition and starvation now stalking this globe. As we see it, 

 the dehydrated food industry, now coming of age, is destined 

 to become America's next frontier of opportunity." 



The Mechanical Cow 



Another development is furnishing food to our fighting 

 man today and will furnish a most vital food to the under- 

 nourished millions of the postwar world. The invention is the 

 "mechanical cow." The "mechanical cow," which is furnish- 

 ing fresh milk on far-flung battlefields and on ships long at 

 sea, works on the same principle as the plasma bank, which 

 furnished blood for transfusions at outposts far from blood 

 donors and blood banks. In the preparation of blood plasma 

 the blood is dehydrated and the flaky powder that results can 

 be shipped anywhere and kept indefinitely. When it is wanted 

 for use, only sterile water is needed to turn it into blood again. 

 Milk for the "mechanical cow" is broken into fats and solids. 

 The solids are dehydrated. The fats are preserved in accord- 

 ance with recent methods for keeping butter fresh in any 

 climate and for indefinite periods of time. The milk pow- 

 der and the butter can be shipped anywhere in the world. 

 When it is wanted for use, it is only necessary to add water 

 and to whirl the mixture of butter, milk powder, and water 

 in a machine and, presto, fresh milk is ready to serve. The 

 product is a far advance over any previous development in 

 milk powders or dried milk. Not only has the "mechanical 

 cow" made fresh milk available in unexpected places, but it
