BY lonking down on The top oi wax candle
a little cup full Of mHlred wax may be seen just
around the wick. The col air keeps the ont.

the melted wax from running dnwn the side.
The wax in the little cup goes up thongh the
wick TO be burned, just as oil DOES in the wick
of q lamp. Il goes up through the lhll passage

Gates fire to the wick.
When the candle is lighted, The heat Of The
burning vapor keeps on melting more wax and
that is sucked up within the alme, where it is
turned into Vap0r and burned aud this process
is continued until the wax is all used up, and the
candle is gone, or burned up as it is termed.
| Notwithstanding the fame of the candle looks

a point. 1t is thus drawn up by the hot air. Hot
air always rises, and that is the way smoke s
