��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 it is necessary to dispatch messcn- gerson important errands, or if the auto- mobile used for such duty is out of repair, the motor- cycle is pressed into use.

When a boy on the ground floor of build- ing "A" is given a note to deliver on the top floor of building "M" he lakes his bi- cycle on an elevator t<j the

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.
