��Putting Wheels Under Workmen Saves Time and Money

THE iirohlcin of intciidr and (.-xlerior transportation in one of the larj^est and busiest ammunition plants in this country — -a plant, by the way, which was constructed in eleven months — has been sol\-ed by the adoption of automobi les, motorcycles, motor- trucifs, hand-trucks, roller- skates and bicycles. The plant is work- ed at high pressure for twenty-four hours a day, and consists of thirteen main units and twelve s e r ^' i (■ ( buildings, each with a main cor- ridor one-half mile long. To inspect the various shops entails a walk of nearly ten miles, exclusive of the stairways. The combined floor area is a million and a half square feet. Between seventeen and eighteen thou- sand employees are on its i)ayroll.

If not detained by the i)arly to whom the note is addressed, he can deliver his answer to the person sending the message within seven min- utes from cHe time he began his jour- ney. Had he de- I)ended upon his legs, the same trip would ha\e taken him at least twen- t\-fne minutes.
