There is no doubt but the form of a
roof has much to do with the draught of
a chimney. The fat roof offers no re-
sistance to the passage of air, but as
the pitch is increased the current is
more and more disturbed, until with a
high-pitched and manygabled roof it is
broken into innumerable eddies, some
of which are sure to curl down and
force the smoke and gases in the fiue
into the rooms below. Chimneys on
such roofs should be built higher than
ordinarily Scientific American.
On a valley farm, two miles east 4t
Parlzersburg w. Va, well-diggers CAME
across an extensive graveyard of an an
tiquity probably exceeding that of the
Cherokee era. The skeletons were
found in a sitting posture facing due
west; but they crumbled at the slightest
pressure though several of the tombs
were protected by superstructure OF
massive stones. Many ornaments OF
bone and shell were found, but nc

When the earth was young, says Dr.
Ball, astronomer royal for Ireland, il
went around SO fast that the day was
only three hours long. The earth was
liquid then, and it spun around anC
around at that fearful speed, and as the
sun causes ever increasing tides upon its
surface it at last burst in two. The
smaller part became the moon, which
has been going around the earth ever
since at an increasing distance. The in
the earth, and while there was any
liquid to operate on in the moon, the
earth returned the mpliment. Irish

A French geologist has made care
