A SUN reporter paid a visit TO the ma

In this city, where one of tho Keely IN otor gen

the parts are either lying completed on the
floor OF In process OF preparation. Among the

feet long and three feet seven inches wide, upon

accessory tubes will he raised. The ch. mbers
are about two feet In diameter, and vary In
height from two to two and half feet. They
are of MASSIVE steel, and their hollows vary
from four to six inches in diameter, leaving the
walls necessarily OF very great thickness and
c n1hle OF bearing an enormous pressure. The
