The fourth process mentioned elertrc shcrnrd-

weather.
BESIDES ovens furnaces, and other devices men
Toned there are n number II small individual"
electrically heated pots furnaces etc. for use in
the shop, garage or even al home. In this class
are compound melting pots. glue pots, metal melt
ers small furnaces and electric soldering irons
Many OF them easily portable In fact
can be attached 10 almost any lighting or shop
circuit For work in book hIndery or pattern
shop for instance the electrically heated pot keeps
the glue continuously at Just the right temper-
ture for use, but never burns II; the may
be said Of the compound melting pot and the lead
or 1abbtt melter. which are ideal for work around
a garage or In n factory, As for the soldering
iron anyone who has used the gas-heated type on
top OF ladder or In some inaccessible place need
not be told the advantages Of an iron that Is al
ways hot and stIll light and well balanced enough
to be used with accuracy and comfort
In spite of its growth In the last few years
the application OF electrical heating to industry
is only In its infancy. The time will undoubtedly
when the effort to conserve our natural coal
and gas resources will cause II to assume much
larger proportions. There is generally no limit
TO It's possibilities Of development not only as
applied to factories but In offices and homes En-
gineers say that the saving OF floor space. cleaner
and more henthfu working conditions to say
nothing Of the improved speed OF production and
superior quality Of work done all tend to make
its universal adoption but a matter Of time
and comparatively short Tina.
