The Bark Canoes and Skin Boats of North America 17

The Bark Canoes and Skin Boats of North America 17


The canoe, as now erected on the building bed, has a double-ended,
flat-bottomed, wall-sided form. The gunwales are sprung to the proper
breadth and sheer, and the bark is standing irregularly above them. At
this point, on canoes not having outwales, the bark cover was laced or
lashed to the gunwales. Since the Malecite canoe has outwales, these
are now made and fitted. They consist of two white cedar battens
about 19½ feet long, perhaps 1 inch wide, and ½ inch thick. The face
that will be the outboard side is usually somewhat rounded, as are all
the corners, and the corner that will be on the inside and bottom of
each batten when it is in place is somewhat beveled. The outwales are
placed between the bark and the outside stakes, the inside stakes being
removed one by one as this is done. The removal of the inside stakes
allows room for the outwale to be inserted in their place, between
the outside stakes and the inner gunwale face, and it allows the bark
to be brought against the outside face of the inner gunwales. In the
process of fitting the outwales, the battens along the sides may have
to be removed and replaced, or shifted, and the cross-ties of each
pair of outside stakes may require adjustment. Beginning at midlength,
the outwale is pegged through the bark cover to the inner gunwales at
intervals of 6 to 9 inches. The pegging is not carried much beyond the
end thwarts in any canoe and could not be in canoes having laminated
gunwales near the ends.
 
The Malecite canoe has bark covers over the ends of the inner gunwales,
and these are now fitted so that they can be passed under the outwales
and clamped in place. The ends of the outwales are forced inside the
stakes at and beyond the ends of the gunwales, assuming a pinched-in
appearance there, and they may reach a few inches beyond the ends
of the bark cover; they will be cut and shaped to the length of the
finished canoe later.
 
The outwale pegs are made by splitting from a balk of birch, larch, or
fir roughly squared dowels about ¼ inch square and 6 to 9 inches long.
Each dowel is then tapered and rounded each way from the middle to
form two shanks that are between and ³⁄₁₆ inch in diameter over 2 to
3 inches of length. The ends may be sharpened by fire. The dowels are
then cut in two, providing a pair of pegs with large heads. These are
driven in holes drilled through the outwales, bark cover, and gunwales,
and when well home, the protruding ends are cut off flush. Toward the
ends of the gunwales, the spaces between the pegs increase, and at
the extreme ends, the outwale will be lashed to the gunwale by widely
spaced groupings of root strand. These are usually temporary, as the
final lashing of the bark to the gunwales will secure the outwales.
 
After the outwales are secured in place, the bark is fastened to the
assembled gunwales with group lashings. In the Malecite canoe being
built, these are independent, each grouping consisting of eight to ten
complete turns of the root strand. The intervals between, roughly 2
inches, are usually spaced by means of a special measuring-stick to
insure evenness. Before the lashing is actually begun, however, the
excess bark standing above the gunwales is cut away. The bark either
is trimmed flush with the top of the gunwale, or enough is left for a
flap that will fully cover the top of the inner gunwale, to be turned
down under the lashing. The latter method, the stronger, was used by
many builders. In making the turns in the group lashings, two or three
turns may be taken through a single hole in the bark; the Malecites did
this to avoid having the holes too close together. The result is that
the group when seen from outboard appears as a ~W~-form, with only two
or three holes in the bark for an entire group. Care is taken to lay
up the turns over the gunwales neatly, turn against turn without open
spacing or overlaps and crossings.
 
When this is completed, the ends of the thwarts can be lashed, the
strand passing through the holes in the shoulders, around the two
gunwale members, and through one or two holes in the bark cover. The
groupings for the bark cover are spaced so that these lashings do not
overlap them, and thus the lashings serve a dual purpose.
 
Next, the gores are usually sewn and the ends of the side panels
closed. To do this, the temporary side battens outside the bark
are removed. Since this is a Malecite canoe, the gores are sewn
edge-to-edge with an over-and-over stitch, the strand crossing the
seam square outside and diagonally inside. When these seams and those
remaining in the upper panels are sewn, the rather stiff bark holds the
shape formed on the building bed to a remarkable degree.
 
The canoe can now be raised from the building bed. To set it up at a
most convenient working height, the weights are first removed from the
gunwales and the remaining stakes are pulled up. The canoe is then
lifted from its bed and turned upside down over a couple of logs, or
crude horses. Traditionally, logs or sapling were rested across two
pairs of boulders or the logs were tied between two pairs of trees at
convenient distances apart. More recently, horses, formed by sticking
four legs into auger holes drilled in the bottom of a 4-foot length
of timber, were used. After the canoe is on its supports the ends are
ready to be closed in.
 
The stem-pieces customarily used by the Malecite builder are formed
from two clear white cedar billets a full 36 inches long and in the
rough nearly 1½ inches square. The billets are first shaped so that
the outboard face of each stem-piece is about ¾ inch wide, making it
a truncated triangle in cross-section. Then, along lines parallel to
the base of the truncated triangle, it is split into six laminations
which are carried to within 6 or 7 inches of the end selected to be the
heel of the stem-piece. Just clear of the laminations a notch is cut
into the top side of the heel, to hold the headboard, as will be seen.
The piece is then treated with boiling water until the laminations are
flexible, and the curve of the stem-piece can be formed and either
pegged out or tied with cords until it dries in the desired shape.
When dry the laminations are tightly wrapped with basswood bark cord,
leaving the form of the stem-piece a quarter arc of a circle, with
short tangents at each end, as shown in the illustration (p. 35).

Next, the ends of the outwales are cut to a length determined by the
quality of the bark already in place; if the bark in one end is not
very good, it may be cut away somewhat and the canoe made shorter by
this amount at both ends in finishing. After the ends of the outwales
have been cut, both are notched on the inside at the extreme ends to
take the head of the stem-piece. The outwales may or may not project
¼ or ½ inch beyond the stem and the stem head may project ½ or 1 inch
above the top of the outwales of the canoe; these matters, at the
builder's option, decide the length of the notch and the fitting of the
stem-pieces.
 
The stem-piece is now placed between the folded bark end of the canoe
with the heel resting for a small distance along its length on the bark
bottom; the head must come to the right height above the outwales, as
noted. While one worker holds the stem-piece in place, another trims
away the excess bark at the end to the profile of the outboard face of
the stem-piece. Thus the profile of each end is cut and the rake of
the ends is established. The bark is next lashed to the stem-piece.
In this canoe it is done with a spiral over-and-over stitch, a batten
made of a large split root being placed over the edges of the bark, as
the lashing proceeds, to form a stem band. The turns pass alternately
from outboard around the inboard face of the stem-piece and through it;
the awl inserted in the laminations from one side opens them enough to
allow the strand to be forced through. Care is taken to pull up the
strand very hard each time. As the outwale is approached, the bark is
cut away at the notching in each so that the outwales can be brought
snugly against the sides of the stem-piece. Here the strand is brought
up one or two times over the outwales, abaft the stem head, before the
bitter end is tucked, thus locking the outwales to the stem-piece and
the bark. Then a lashing is placed around the outwales just inboard
of the stem-piece, passing through a hole in the flap of the end
deck-piece of bark and through the side bark. This lashing holds the
outboard end of the deck piece flap. At the inboard end of the flap,
another lashing is required, but the pinched-in outwales require
additional securing outboard of this point; hence a lashing is passed
just inboard of the middle of the flap, a little outboard of the ends
of the inwales, and about six inches inboard from this lashing another
is passed through the side bark and around the gunwale and outwale on
each side. These three lashings hold the outwales snug to the ends of
the gunwales and against the projecting bark ends in the pinched-in
form of projecting outwales.

The heels of the stem-pieces rest on the bottom bark and the sewing is
carried down to where the cutting of the profile makes an end to the
seam, the solid part of the heels extending about 6 to 8 inches inboard
of this. Next, any sewing required on the bottom is done. When the bark
cover has been given a final inspection on the outside and all sewing
has been completed, the canoe is lifted from its supports, righted, and
set on the bed or on a smooth grassy place.
 
All seams are now payed with gum on the inside of the bark while this
can still be done without interference from the sheathing or those
parts of the structure remaining to be installed. The Malecites used
only spruce gum tempered with animal fat. The gum, heated until it is
sufficiently soft to pour like heavy syrup, is spread with a small
wooden paddle or spoon, and is then worked into the seam and smoothed
by rubbing with the thumb dipped in water to prevent the gum from
sticking and burning. It is first worked into the ends, between the
bark and each side of the stem-pieces, particularly near the heel below
the waterline. When the crevices are filled, a piece of bark (in later
times a piece of cloth was used) wide enough to cover the gum alongside
is well smeared with warm gum and pressed down along the inside of the
stem-pieces. On each seam, at gores, and on side panels a thin narrow
strip of bark is smeared with gum and pressed over the seam after the
latter had been well payed. The bark is now carefully scrutinized for
small splits, holes, or thin spots since these can be easily patched
from the inside at this stage of construction. In fitting bark strips
and in gumming, great care is taken to obtain a flat surface; the edges
of the strips inside are faired to the inside face of the bark by
smearing gum along the edges. The canoe is now ready to be sheathed and
ribbed out.
 
The sheathing for this canoe has been split in advance out of clear
white cedar in splints about 5 to 9 feet long, 3 to 4¼ inches wide, and
inch thick. The butts of each piece have been whittled to a feather
edge, the bevel extending back about 2 inches. Also, some pieces of
basket ash have been split out of saplings for temporary ribs to hold
the sheathing in place.
 
A total of 50 or more ribs in five lengths, the longest about 5 feet,
have been made up from white cedar heartwood and bent to the desired shape.
