DIR. GRAHAMs INVENTION.
A New Gas Discovered by Savannah's

tails of Europe. He will, however. spend
some considerable part of his time ac-
quainting himself with the languages, GUS
toms and laws Of the principal European
nations.
DIR. and Mrs. Graham carry with them
the esteem and good wisIes of a large
circle of friends, whom they have mace
in Savannah, and who are glad to know
that at the end of the European tour the
doctor and his wife will return to make
their home in Savannah.
As quarantine officer DR.. Graham had
a great deal of time on his hands when
his attention was not required by his or

singly or mixed In any proportion He
has been two years In perfecting his dis
coveries, which he expects will yield some
remarkable results. The apparatus is any
ordinary stove engine fire box or furnace,
in which charcoal or sulphur may be
burned. The gases resulting from this
combustion are drawn through water
chamber to wash them and remove an
sparks and solid particles of matter and
to purify them. Direct-acting air
pumps then compress the gases to any de-
sired pressure in cylinders. The gases may

over and over again, its cheapness and
