Match

For the Match
or Flash-faggot
try straws of different
bores, and
different intervals
between the straws
to see which is most
favourable to the
maximum of heat
& quickness of ascension.

Much will depend
on the driness
of the Straws.
Moisture besides
retarding the ascension
will diminish
the heat.

The cocks, though
disposed in a

The straws should
