\ MAMMOTH ELEVATOR PLANT.
The Sprague elevators. Of seventeen sizes and
types to meet all classes Of service. manu-

Here. three miles beyond Newark, is the largest
elevator manufacturing plant in the world. 1t
covers a hundred thousand square feet ana is
fully equipped with the best machinery to be
had. much of it mad" according to special de-
