According to the Science Summary,

A letter from John E. Martin to the Railroad
QautU contains the following: I notice in the
discussion on boilers at the last convention of
master mechanics, that Mr. Hudson recom
mends washing ont locomotive boilers with hot
water. I have used the injector for that pur.
pose lately and with great success. We conn
uie boilers to be washed ont with the injector
of another locomotive by means of wrought-iron
piping and a flexible hose pipe that will srju,d,
good pressure. A nozzle of five-sixteenths of
an inch is used on the hose. With snch
nozzle and with a boiler pressure of about 130
pounds we throw a stream of hot water of 140'
Fahr. temperature into the boiler to be washed
out. A gauge on the hose pipe showed a prei
sure of 1 10 pounds, equal to a vertical weight of
nearly 250 feet The hot water loosens th.
scale more effectually than cold water, and the
force of the stream is all that can be desired
A stream of water can be thrown a distance of
60 feet and could be used aa a fire extinguisher.
