The osiers may average a little more than 1/2 in.
in thickness and should be cut, stripped of leaves
and bark and put in place while green and fresh.
They are attached to the bottom by means of shingle
nails driven through holes previously made in them
with an awl, and are then bent down until they touch
the strips of ash (b, b, Fig. 3), and finally cut
off even with the tops of the gunwales, and notched
at the end to receive them (B, Fig. 4). Between
the cross-boards the ribs are placed at intervals
of 2 or 3 in., while in other parts they are as much
as 5 or 6 in. apart. The ribs having all been
fastened in place as described, the loose strips of
ash (b, b, Fig. 3) are withdrawn and the framework
will appear somewhat as in Fig. 1. In order to
make all firm and to prevent the ribs from changing
position, as they are apt to do, buy some split cane
or rattan, such as is used for making chair-bottoms,
and, after soaking it in water for a short time to
render it soft and pliable, wind it tightly around
the gunwales and ribs where they join, and also interweave
it among the ribs in other places, winding it about
them and forming an irregular network over the whole
frame. Osiers probably make the best ribs, but
twigs of some other trees, such as hazel or birch,
will answer nearly as well. For the ribs near
the middle of the boat, twigs 5 or 6 ft. long are required.
It is often quite difficult to get these of sufficient
thickness throughout, and so, in such cases, two twigs
may be used to make one rib, fastening the butts side
by side on the bottom-board, and the smaller ends
to the gunwales, as before described. In drying,
the rattan becomes very tight and the twigs hard and
stiff.
The frame-work is now complete and ready to be covered.
For this purpose buy about 18 yd. of very strong wrapping-paper.
It should be smooth on the surface, and very tough,
but neither stiff nor very thick. Being made
in long rolls, it can be obtained in almost any length
desired. If the paper be 1 yd. wide, it will require
about two breadths to reach around the frame in the
widest part. Cut enough of the roll to cover
the frame and then soak it for a few minutes in water.
Then turn the frame upside down and fasten the edges
of the two strips of paper to it, by lapping them
carefully on the under side of the bottom-board and
tacking them to it so that the paper hangs down loosely
on all sides. The paper is then trimmed, lapped
and doubled over as smoothly as possible at the ends
of the frame, and held in place by means of small
clamps. It should be drawn tight along the edges,
trimmed and doubled down over the gunwale, where it
is firmly held by slipping the strips of ash (b, b)
just inside of the gunwales into notches which should
have been cut at the ends of the cross-boards.
The shrinkage caused by the drying will stretch the
paper tightly over the framework. When thoroughly
dry, varnish inside and out with asphaltum varnish
thinned with turpentine, and as soon as that has soaked
