ington, to the effect that bacteria are
affected favorably or otherwise by the
character Of the glass containing the
water in which they are suspended.
Marked differences in the behavior Of
cholera germs were noted, according to
the kind of glass composing the vessels
used The degree of alkalinity impart-
ed by the glass to the water Is believed
to be an important factor III these ex.

Over 5OO.OOO,O 900 gallons Of water are
pumped out Of the anthracite coal
mines Of Pennsylvania every day In the
year. The exact average for 1905 was

powerful engines, delivering from mine
bottom to surface 100000 gallons Of
water q minute. are required. Mines
may be shut down and coal production
suspended, but the water flows OH for.

Coal Is fossil peat The peat.bogs
OF today might become coal beds In
some future geological age. Professor
Potonie OF Berlin says there Is strict
parallcllsm between the different kinds
of peat and of coal When the remains
OF plants collect under terrestrial
conditions. IN ordinary peat bog Is
formed. This corresponds with bright"
coal. II the remains collect under wa.
ter, an organic slime is formed. and
this corresponds with dull" or camel,
coal. When terrestrial ana aquatic
conditions have alternated during the
collection OF the remains. "strata.peat"
results. ana this corresponds with coal
deposits consisting Of alternate layers
OF bright and dull coal. The chemical
and physical properties OF the various
kinds Of peat and coal show similar
correspondence.
