Take a sheet of very heavy paper, at least one inch larger in every
dimension than the top of the box. Draw a circle in the centre of it the
size of the pail. In the centre of this circle cut a small hole large
enough to insert the blade of a pair of scissors. From this hole, cut to
the circle, so as to strike it at intervals of about one and one-half
inches. (Fig. No. 4.) Fit the paper over the top of the packing in the
box so that this circle will come just over the nest for the pail. Put
the cooker-pail into the nest and it will crease the points down at
exactly the right place. Figure No. 5 shows the cooker completed. A
paper lining is in some respects to be preferred to cloth. It is easy
and quick to make and can be readily replaced if it becomes soiled.
With either class of cooker more than one nest may be made. It is well,
in that case, to have a wooden partition put into the box before
packing it, although this is not strictly necessary. Each portion of
the box can then be packed independently and for utensils of different
sizes if desired.
