the flow Of steam being also regulated by sop-cock
placed In the vicinity Of the furnacedoor near the

The water in the boiler being cold SIXTY degrees at
fifteen minutes past pm. some blets Of pine wood and
shavings. weighing about twelve pounds being placed
upon the coil near the furnace door, were lighted and
the door partially cosed after an interval OF fifteen min
utes. the oil-cock. N, was gradually opened. which
permitted flow Of oil from the reservoir through the
coil; simultaneously with which. or little later, the
steam cock. r. was opened. which conveyed steam o,

retort or mixer b. where combining with the vspor OF

fame was vivid and intense regulated in its force by
the relative flow OF oil and steam. and was entirely

Steam atmospheric pressure was raised In the boiler
in twenty nine minutes from the time OF admission o.
oil into the coil. No measure was taken In this expert
