Tho remaining cylinders will run as
tripie-eNpansi0n engines. This result IS
accomplished by having two SETS OF boil

the coil boilers viii supply steam directly
to the high pressure cylinders. while the
shell boilers will deliver their steam TO

In tine boior-room there viii be four

with a total heating surface Of $3.50 square
feet These boilers viii supply steam
to the cylinders of two quadruple expaB-
