Before raising the kite, the string, which hangs from K', is made fast at
K in such a way as to cause the bow to curve backward. This curvature is
increased or diminished according to the force of the wind.
Nothing remains to be done but to attach the cord to the balance, and
raise the kite.--_La Nature_.

APPARATUS FOR DRYING FLOUR.
The accompanying drawing represents a simple but effective apparatus for
drying flour and ascertaining the quantity of water contained therein. It
consists of four pieces, the whole being made of block tin. A is a simple
saucepan for containing the water. B is the lid, which only partially
covers the top of the pan, to which it is fixed by two slots, a hole
being left in the middle for the placing of the vessel which contains the
flour to be operated upon, and is dropped in in the same way as the pan
containing the glue is let into an ordinary glue pot. C is the spout,
which serves as an outlet for the steam arising from the boiling water. D
is the vessel in which the flour is placed to be experimented upon; and
EE are the funnels of the lid which covers the said vessel, and which
serve as escapes for the steam arising from the moisture contained in the
flour.
