The Bark Canoes and Skin Boats of North America 44

The Bark Canoes and Skin Boats of North America 44


The midsection was usually quite round, almost ~U~-shaped, on the
bottom, but some canoes showed the bottom slightly flattened and the
sides flared out somewhat. Toward the ends, the ~U~-shape became
marked, and near the gunwale ends the sides of the ~U~ fell inboard
slightly as they came to the gunwales, the bottom of the ~U~ having a
hard turn. In plan, the gunwales approached the stems without hollow,
being nearly straight or even slightly convex. The ram was long and
sharp in its lower level lines and this, with the form of midsection,
made this model a fast-paddling canoe, though rather unstable. Most of
these canoes had but one thwart, placed at midlength, but some have
been found with three thwarts and a thong tie across the gunwales,
close to the stems, as well.
 
No stem-pieces were used; the bark ends were closed by two outside
battens, one on each side, whose heads were carried some 3 inches above
the gunwales. A cutwater batten was placed over the edges of the bark
between the battens, and the three were lashed together, with the bark,
by a coarse spiral wrapping or by group ties. The bark cover was not
sheathed inside; instead, six battens, by 1½ inches, were placed on
each side of the keel piece, which measured about ½ by 3 inches and
tapered toward the ends. The battens, widely spaced, ran well into the
ram ends, and were held in place, like sheathing, by the pressure of
the ribs. The ribs, spaced 8 to 12 inches on centers, were often split
saplings; sometimes they were shaped to approximately ¼ by ¾ inch. The
batten nearest the gunwale on each side was lashed to every rib. In
some canoes the heads of the ribs were brought up between the inwale
and outwale, inside the bark cover, with their ends against the cap.
The stitching of the longitudinal seam of the topside panel was passed
around these frames and so helped to secure them. In one example, the
ribs were passed through the bark cover just below the horizontal seam
of the topside panel; there a turn of the stitching was passed around
each rib; then the rib was brought inboard again in the seam by being
passed between the edges of the bark cover and the panel. In many
canoes there were no ribs in the ram ends, but this was not universal
practice; small light ribs were sometimes placed there, with their
heads caught in the closure lashing of the end.

The canoes had 3-part gunwales consisting of inwale, outwale, and cap,
but in many the arrangement of these was such that this nomenclature is
misleading. In the latter construction, a lower inwale was used, as in
the above drawing; rather small in cross section, it was almost square,
with rounded edges. The rib ends, after passing through slits in the
bark cover below the lower inwale, continued upward past it, outside
the bark cover. Above the lower inwale and inside the bark cover was a
larger upper inwale; this was flat on the outboard and bottom sides,
the top and inboard sides being rounded into one another. The outwale,
roughly rectangular in cross section, clamped the bark cover and heads
of the ribs between it and the upper inwale. The ribs and bark were
trimmed off flush with the tops of the outwale and upper inwale. The
thwart amidships was caught, at the ends, between the lower and upper
inwales. The gunwale members and bark cover were secured by group
lashings of small extent and rather widely spaced.
 
The methods of fitting the thwarts differed in this class of canoe,
and it cannot be determined with certainty whether this variation was
tribal or the choice of the individual builder. In canoes having the
lower inwale arrangement there was but one thwart amidships. As has
been said, its ends were caught between the upper and lower inwales.
Directly beneath it was a rib whose head was not brought up outside
the bark cover but, after being secured to the uppermost sheathing
batten, was brought around inboard in a quick hard turn and secured
along the underside of the thwart with a close spiral lashing. Under
this rib at the topmost batten was secured a short false rib head by
forcing the beveled foot of the false rib between the batten and the
true rib, after lashing; the head of the false rib was then brought
up through and outside the bark cover in the customary manner, or it
might be forced under the lower inwale, inside the bark cover. In this
construction, the endmost ribs were at the gunwale ends, and the heads
of these were lashed to the stem battens outside the gunwale ends, on
the outside of the bark cover.

In canoes having the usual gunwales of inwale, outwale, and cap, the
inwale and outwale were roughly rectangular, with their top sides
horizontal, and the cap, very small and light, was flat on the bottom
and rounded on top. In this construction, the rib heads usually were
clamped between the inwale and outwale, inside the bark cover.
 
The ribs of the ends were lighter than those of the main body and
more closely spaced, say 2 or 3 inches apart. These began about 8 or
9 inches inboard of the gunwale ends; the heads did not reach the
gunwales, but instead were caught in the horizontal seam of the side
panel and then cut off. Usually three ribs were so fitted. The rest of
the end ribs, usually eight in number, either had their heads caught in
the stem lashings or were made up as hoops with the heads overlapped
and lashed together, the ribs being placed so that the overlap came to
one side or the other of the canoe. Each hoop was usually caught by a
turn in the end-closure lashing.
 
To strengthen the ram, the lower ends of the three stem battens were
lashed to the extremities of the inside keel-piece, which was brought
through the bark cover at this point. The opening resulting from this
was sealed with gum or pitch. Minor variations in construction have
been noted in the canoes exhibited in museums; in one, for example,
only every fourth rib was caught in the topside panel stitching.
 
In canoes having the usual arrangement of gunwale members, with the
cap over the ends of the ribs, the ends of the thwart were sometimes
carried some 6 to 8 inches beyond the gunwales, at each end, and much
reduced in thickness by cutting away about half the depth of the
thwart. This part was then wrapped tightly around the inwale, brought
inboard along the underside of the thwart, and there lashed. Examples
show that the amount of end brought inboard under the thwart varied
with the builder. It should be added that the thwarts were usually no
more than barked saplings and were obviously installed in the canoe
when green and treated with hot water so they would not break when
wrapped around the inwales. In canoes having three thwarts, all were
fitted in this manner, but often the thwarts on each side of the middle
were also wrapped in a long spiral with a thong whose ends were tied
to each gunwale. In 3-thwart canoes, there was commonly a cross tie,
located roughly 12 inches from the gunwale ends and consisting of three
or more turns of cord, or thong, around the gunwale members on each
side and athwartships, secured by turns of the ends around the cross
tie. In one canoe there was a thwart amidships and one at one end,
about halfway between the middle thwart and the gunwale ends; at the
other end were two cross ties, one replacing the thwart and another a
foot inboard of the ends of the gunwales. In this canoe the ribs at the
gunwale ends were hoops and there were only three hoop ribs in the ram
ends.
 
One canoe, from Stevens County, Washington, had a peculiar double
framing. The sheathing battens, instead of being on the inside of the
bark cover, rested on light ribs, spaced about 6 inches apart, that ran
only far enough up the sides to have their ends caught in the stitching
at the bottom of the topside birch-bark panel along the gunwales. The
longitudinal battens were placed inside these, with the batten nearest
the gunwale lashed to the light ribs. Inside these battens and spaced
about a foot apart was another set of ribs whose heads were secured
between the inwale and outwale inside the bark cover; each of these
inside ribs was also lashed to the uppermost batten. Only the keel
batten was under the small ribs. The thwart ends were wrapped around
the main gunwale members, and the stem battens were secured to the
birch topside panels by but one group lashing, near the gunwales. The
bottom cover was stiff pine bark.
 
The topside panel of birch bark was placed in these canoes so that its
grain was horizontal instead of the usual vertical. Presumably this was
done as a maintenance solution: the panel was much easier to repair or
replace than the bottom bark; and by having the panel placed in this
weak mode, it would split before the bottom bark if too much pressure
were brought on the framework in loading.
 
These canoes paddled well in strong winds and in smooth water, and
worked quietly in the marshes where they were much used. Canvas canoes
of the same model replaced the bark canoes, indicating that the model
was suitable for its locality and use. These sturgeon-nose canoes were
so different from other North American bark canoes that they have been
the subject of much speculation, particularly since ram-ended canoes,
though of different construction, existed in Asia.
 
The size of the Kutenai-Salish sturgeon-nose canoes varied; the most
common size appears to have been between 14 and 20 feet over the ends
of the rams, 24 to 28 inches beam, and with a depth ranging from 12
to 13 inches amidships and from 14½ to 17½ inches at the ends of the
gunwales. However, records exist that show rather large canoes were
built on this model, 24 feet over the rams, 48 inches beam and 24
inches depth.
 
The building methods of this type of canoe have never been reported.
Probably some kind of a rough building frame was used. Perhaps this
was comprised of a couple of the battens and the keel piece, weighted
with stones. The building bed was probably level. The main gunwale
members were apparently made up temporarily and the bark cover shaped
and staked out. From that point the work may have followed the usual
canoe-building practices except that the ends could not be closed until
the framing there was complete, otherwise it would have been impossible
to fasten the small ribs in the rams. The structure of these canoes
appears to have been almost entirely cedar, except for the bark and lacings which, in some instances, were partly some bark fiber as well as roots. In general, the construction of this class of canoe did not match in quality that of the other bark canoes of the Northwest.
