It would take q smart air condi-
toner of a few years ago to even
recognize this industry's 1910 Of
spring. If you haven't looked at
cooling devices for quite some time
you will be surprised to find how
compact and efficient looking the
units of today are compared with
the bulky, unwieldy machines which
were brought out four or five years
ago. You may remember that those
original units, which were as port
able" as a grand piano, required
elaborate plumbing and electrical
installation work and still had only
enough capacity to cool a rather
small room.
Nowadays it's a different story.
A large number of well-designed
air conditioners are now on the
market which not only fulfill a
large majority of the requirements
for true air conditioning" such as
cooling, decentralization, filtering
and air circulation, but do so out
of a box which is a fraction of the
size OF their gigantic predecessors.
With really hot weather hard upon
us, your home will welcome one or
more OF a new line of air condi-
tioners recently brought out which
are designed to do specialized Jobs.
II you want to cool only your bed
room at nighttime, you can install
a small conditioner with minimum
capacity to do the job, and at a
lower cost, naturally. If you want
to cool an average-sized room during
the daytime, such as living room
or office, you can get larger unit
OF similar design and construction
but of added capacity. Larger
rooms In your home or Office also
can be adequately cooled with still
larger machine of somewhat diff
ferent design.
The first two Of these new units
are made in the popular self-con-
tanned style for mounting in partly
opened window. They contain a
powerful Theoretically sealed cooling
unit complete with the necessary
fans for the circulation of outside
air through the machine for fresh air
supply and heat dissipation. Their
cabinets are made of attractively
designed sheet steel decorated with
handsome wood granting or solid
colors to match room color schemes,
and according to the manufacturer
they may be installed in an ordinary
window in the brief space of five
minutes.
Unit number three also is a good
looking piece of comfort equipment
and is similar to the others except
that 1t is floor model to be placed
in front of partly opened window
and connected to the outside air by
means of small connecting duct.
All of these units require no plumb
ing connections of any kind since
they are air-cooled and the con-
densed moisture is blown out of the
window in fine mist. Nor do they
require any special wiring because
they may be plugged into an ordi-
nary floor plug for the electrical
supply.

Here is another type of fence ma
terial which can be used not only as
q road-edge barrier, but for making
wells around trees, hiding the gar
bage can, preventing trespassing and
keeping animals from beating paths
to their doors via your grounds.
Because of its extreme flexibility it
can be worked around into all sorts
Of shapes and designs for your
flower garden beds or along the
edges of the most circuitous drives.
known as an interlocking drive
In fence, this new steel product is
certainly of clever design and should
be very easy to put in place. The
fence units consist of double -arched
sections about 4 inches wide, which
have interlocking joints on both
outside edges. They are available
in lengths, or depths, of or 6 inches
for borders, and IL, "a and So inches
for deep fencing. On special order
they may also be had in lengths
of feet for use in protecting a
flower bed from hedge roots and
acting as wind break.
To install your fence, all you
have to. do is drive one unit after
another into the ground with an
ordinary hammer, inserting one in
terlocking edge into the next as you
60 along. This forms an endless
pattern which will remain strong
and firm regardless of the type of
ground you are inclosing. 1t can
be obtained in a number of diff
ferent materials, depending on how
much you want to invest in per-
manence. A hard cold rolled zinc
fence has bright silver finish,
