While mechanical refrigeration is q
comparatively new branch of engineer
ing, IT'S many advantages over the old
method of cooling by means of natural
Ice has caused the industry to grow fan
more rapidly than is generally known
to the public. Confined at first to large
cold storage plants, ocean liners, beet
warehouses, and breweries, refrigerat-
ing machinery is now commonly found
in meat markets, produce exchanges,
steam yachts, merchant and naval yes
sells, hotels, apartment houses. diaries,
and various manufactures; and as
business enterprise increases the de-
mand for such machinery, and as busi-
ness competition continually lowers its
price and increases its efficiency, 1t is
not improbable that the use OF natural
ice for cooling purposes viii be largly
abandoned in the near future.
Natural ice otten contains snow, or
ganlc matter that decays as the ice
lneIts, and various disease germs. IN

storage, anu delIvery, occupies a large
amount or space, and the lowest tenn

above the freezing point. Mechanical
refrigeration proauees supply OF dry,

industry, and the superior quality and
economy OF the manufactured article
makes it a successful competitor OF nat
ural ice.
in no other line of work is technical
knowledge more necessary or valuable
than in those pertaining to refrlgeIa-
ton, as very little information OF value
on the subject has ever Deen obtalnaole,
and the scarcely of men competent TO
operate or design ice-making and re-
frIgerating machinery Is constantly in
creaSing the high sataries already paid
for this class OF work,
The Correspondence Schools Course
includes instruction in Arithmetic,
Mensurabion, Elementry Algebra and
Irigonometrlc Functions, Logarithms,
Elementary Mechanics, PneumatIcs,
Heat, steam and Steam Engines, Prin-
ciples OF Refrigeration, and Ice-Making
and Refrigeraung Machinery. 1t is IN
tended for two classes: first, steam en-
gineers and others who wish to learn
how to install, test, operate, and repair
refrigerating machinery; and, second,
designers and builders who wish to
manufacture ice-making and refrigerat-
ing machinery.
Through his course the first class
will learn to make the various calcula-
tions relating to the operation and
testing of steam engines and refrdger-
ating machinery, Will understand the
methods of handling the gases and
mixtures used, and the principles and
successful operation OF refrigerating
apparatus.
The second class will acquire
| knowledge of mathematics, mechanics,
expansion and compression OF gases,
principles of refrigeration, and the pro-
portion of pants in design necessary for
effective and economical service. The
writer OF the advanced papers mas nao
a large experience in the design, manu-
facture, and installation OF refrigerat-
ing machinery, and this course pro-
vides the most valuable information on
the subject extant.
This course may be selected by any
of the prize winners in the Registers
coupon contest, now going on. There
is a wide choice of courses, and from
/ day to day we intend to present an out
line of each. Make your selection and
| in the meantime save your coupons and
ask your friends TO vote for you. The
co.Ncst closes at midnight February
