mesh and frame
from being shaken off the box. The projecting edges of the mesh
would keep the frame on the top edge of the box. The top view of
the frame is shown in Fig. 1 and the end in Fig. 5, and the box on
which the frame rests in Fig. 3. The actual size of the wire mesh
used is shown in Fig. 4. One person could hull with this huller as
many berries as two persons would pick.

** How to Make a Bulb on a Glass Tube [324]

As a great many persons during the winter months are taking
advantage of the long evenings to experiment in one way or
another, the following method of forming bulbs on glass tubes may
be of interest. A common method is to heat the part to be formed
and by blowing in one end of the tube gradually expand the glass.
This way has its drawbacks, as many are not sufficiently familiar
with the work to blow a uniform blast, and the result is, a hole
is blown through the side of the tube by uneven heating or
blowing.

A good way to handle this work, is to take the tube and 1 or 2 in.
more in length than the finished article is to be and place one
end over an alcohol flame, and by holding a spare piece of tubing
against the end allow them both to come to a melting heat, then
pull apart and instead of breaking off the long thread thus
formed, simply hold it in the flame at an angle of 45 deg. and
melt it down and close the end at the same time. Close the other
end with the same operation; this makes the tube airtight.

Gradually heat the tube at the point where the bulb is to be
formed, slowly turning the tube to get a uniform heat. The air
inside of the tube becoming heated will expand, and the glass,
being softer where the flame has been applied, will be pushed out
in the shape of a bulb. A great deal of care should be taken not
to go to extremes, as the bulb will burst with a loud report if
the heat is applied too long. The best results are obtained by
heating the glass slowly and then the bulb can be formed with
regularity. This is an easy way to make a thermometer tube. After
the bulb is formed, the other end of the tube can be opened by
heating, drawing out and breaking the thread like glass.
