in itself all the desirable qualities
OF the r~otativo engine with the
minimum amount Of friction and

A COMPOUND, coSDESsiSo ESorSK.
Horizontal. diiect-sctiug. lifted with hy-
wheels which give It . rotative motion.
The initial cylinder IL placed beside the
expansion cylinder and hasa diameter Of
81 inches. The expansion cylinder 10 81
inches in diameter aud both have . stroke
Of ~ feet In the clear. Some idea OF the
solidity Of this engine may DO gAined from
its immense weight and tho massiveness
and strength OF the foundation upon
which Ii rests. The initial cylinder weighs
$3.50 pounds and tho expansion cylinder
1880 pounds. Tho heads OF these cyl.
inders alone weigh nearly tan tons. The
cro-shcad upon which the piston rods act
and which moves backwards and forwards
with every stroke. weighs $4,000 pounds.
the FOUNDATION
Upon which this monster rests are u solid
as the everlasting hills. The sols'plsis
consists Of seven sections firmly bolted
together. their combined weight being
iO2.7 200 pounds. These lie On coping
stones and these In turn on ashlars. which,
with their beds Of rubble extend TO
depth Of 40 feet. Tho solo-plsts IL held In
place by 81 vertical frame bols and eight
angle bolts. three inches in diameter and
extending down % feet. The foundations
contain $3.50 perch Of rubbls and 3.3G3t
feet Of ashlar and coping stone and cost

THE ESaISE Is yrrrKD UP
With o'Neil's cutoff. and has Cornish.
double-beat induction and American or

with the cross-head on the outside. each
connecting rod weighing 1900 pounds.
The main connecting rod runs from tho
center Of tho eross-head 10 the bish-
op-head Of the bob, and weighs
81, $50 pounds. The first connection
down the shaft weighs 1850 Ms. The
