Pin production in the United States has reached a high stage of development. The number of pins made in 1914 reached the tremendous total of 25,000,000,000. These figures are almost too great for comprehension. If all the pin wire used for these 25,000,000,000 pins were in one piece it would go around the earth fifteen times. Safety pins, hooks and eyes, and hairpins, are generally made by pin concerns. Each of these different articles require very ingenious machines. Many of them are almost human in their operation.
The popular name of the prominence seen in the front of the throat in a man is called the “Adam’s apple” because of the story in the Old Testament, telling of the eating of the forbidden fruit of the tree of knowledge by Adam, a piece being supposed to have lodged in his throat where the bulge appears.
