n8 Miracles Ahead! 



people who entered, and not switch off the light until the last 

 person had left the room. In fact, phototubes used to control 

 traffic in one-way tunnels exercise just such ability to count 

 even now. 



Doubtless we can all remember a rime in our childhood 

 when we watched the pharmacist at the corner drugstore 

 weighing the powders for a prescription. It was a long and 

 tedious process. But, thought we, it takes time to get things 

 exactly to a fraction of an ounce! Today electronic watch- 

 men can weigh thousands of objects, instantly discarding any 

 that are overweight or underweight by a thousandth part of 

 an ounce and do it all in seconds instead of minutes! 



Testing the Ripeness of a Melon 



Electronic inspectors adapt themselves exceptionally well 

 to conditions where the ebb and flow of production is irregu- 

 lar. When a sudden spurt of production occurs, they can 

 work tirelessly, day and night, with unfailing speed and ac- 

 curacy. When production stops, they present no labor prob- 

 lems. Fruit growers have saved themselves thousands of dollars 

 by using electronic inspectors for rapid sorting of fruit. 

 Overweight, underweight, and off-color fruit is discarded 

 with lightning speed as it whirls by at a speed which would 

 overtax a corps of human inspectors. 



Electronic testers can even check the ripeness of a melon, 

 and tell you exactly when it reaches that state of luscious per- 

 fection that makes it worth the price! What a boon to the 

 purchaser! And the electronic tester makes its test without 

 bruising the fruit! What a boon to the merchant! 



It is possible that someday an up-and-coming fruit market 

 will install a "melon checker," just as the chain drugstore in- 

 stalls a tube checker for radio tubes. Surely it would pay for 

 itself in a short time if flashing lights informed the prospec-
