THE NATIONAL GEOGRAPHIC MAGAZINE 



A BATTERY OF CALENDER PRESSES AT WORK FINISHING MAGAZINE PAPER 



After the coated paper has been dried and put into rolls, as shown in the preceding pic- 

 tures, it is brought to the room shown here. A roll is put in the reel at the man's shoulder 

 in the foreground and started through the machine. It passes between the two top rollers, 

 and then in and out between the succeeding rollers, until it reaches the bottom. Many tons' 

 pressure have ironed it before it comes out and is rolled up again. This process gives it the 

 finish that the National Geographic must have to maintain its high standard. 



machines employed in the making of 

 watches ; but to visit a great Massa- 

 chusetts watch factory and there to see 

 some of the operations of making a good 

 timepiece is to behold the highest de- 

 velopment in mechanical accuracy and 

 quantity production. 



STEEE HAIRSPRINGS WORTH $49,000 A 

 POUND 



Here one sees alloy steel wire worth 

 rive dollars a pound being converted into 



hairsprings, some so delicate that they 

 are worth $49,000 a pound. There a 

 machine is taking in steel wire and turn- 

 ing out microscopic screws with perfect 

 heads and threads and slots, yet so small 

 that the ordinary eye wants a magnifying 

 glass to perceive that they are aught but 

 specks of steel. In another place is a 

 machine which transforms bare blanks 

 into completely bored movement plates 

 without the interposition of a human 

 hand.
