t length for the boiler used, is all that need be carried to
make renewals.

Repairs in water-leg boilers are difficult at best and frequently
unsatisfactory when completed. When staybolt replacements are necessary,
in order to get at the inner sheet of the water leg, several tubes must
in some cases be cut out. Not infrequently a replacement of an entire
water leg is necessary and this is difficult and requires a lengthy
shutdown. With the Babcock & Wilcox boiler, on the other hand, even if
it is necessary to replace a section, this may be done in a few hours
after the boiler is cool.

In the case of certain staybolt failures the working pressure of a
repaired boiler utilizing such construction will frequently be lowered
by the insurance companies when the boiler is again placed in service.
The sectional nature of the Babcock & Wilcox boiler enables it to
maintain its original working pressure over long periods of time, almost
regardless of the nature of any repair that may be required.

Durability--Babcock & Wilcox boilers are being operated in every-day
service with entirely satisfactory results and under the same steam
pressure as that for which they were originally sold that have been
operated from thirty to thirty-five years. It is interesting to note in
considering the life of a boiler that the length of life of a Babcock &
Wilcox boiler must be taken as the criterion of what length of life is
possible. This is due to the fact that there are Babcock & Wilcox
boilers in operation to-day that have been in service from a time that
antedates by a considerable margin that at which the manufacturer of any
other water-tube boiler now on the market was started.

Probably the very best evidence of the value of the Babcock & Wilcox
boiler as a steam generator and of the reliability of the apparatus, is
seen in the sales of the company. Since the company was formed, there
have been sold throughout the world over 9,900,000 horse power.

A feature that cannot be overlooked in the consideration of the
advantages of the Babcock & Wilcox boiler is the fact that as a part of
the organization back of the boiler, there is a body of engineers of
recognized ability, ready at all times to assist its customers
