locate stakes temporarily on building bed. Instead of the gunwales, a
building frame was used in some areas. (_Sketch by Adney_.)]
 
The second pair of thwarts is placed 30 inches, center to center, from
the first pair, one at each end, and on the basis of this measurement
the tenons are cut as for the others. These two thwarts are made of
-by 4-inch pieces tapering in thickness each way from the center to
the shoulder, where they are a scant ⁵⁄₁₆ inch thick, the tenons having
the same dimensions as in the other thwarts. In width the thwarts are
worked to an even 3 inches from shoulder to shoulder, but in the form
of a curve so that when each thwart is in place its center will be
bowed toward the ends of the canoe, viewed from above. As in the first
pair, the shoulders and ends are cut to a bevel to fit the gunwale;
at the centerline they each measure 12 inches shoulder-to-shoulder in
a straight line athwartships and 15 inches end-to-end. Allowing for
bevel, the maximum length is just over 15-⁵⁄₁₆ inches. These thwarts
are drilled for single gunwale lashings and the corner edges are well
rounded from shoulder to shoulder. The distance from the centerlines
of these last thwarts at the bow and stern to the extreme ends of the
joined gunwales is 33 inches, so the finished gunwale length is 16 feet.
 
After the endmost thwarts are pegged into place, the temporary stays
are removed. At each step of construction the alignment of the gunwales
is checked by measuring with the measuring sticks and by sighting,
since the shape of the assembled gunwales, in this case of the inner
gunwales, is very important in determining the sharpness of the
completed canoe and the fairness of its general form.
 
The assembled gunwales are now ready to be laid on the building bed
which, for the Malecite canoe, is 20 feet long, about 3½ feet wide and
is raised about 1½ inches at midlength so that the canoe bottom will be
straight when the craft is in the water. The gunwale frame having been
carefully centered on this bed, with the middle thwart exactly over the
highest point in the surface of the bed, some scrap split-planking is
laid across the gunwales and the whole weighted down with a few flat
stones. Next, 34 stakes from 30 to 50 inches long are prepared, each
made of a halved length of sapling. Around the outside of the gunwale
frame 26 of these are driven in pairs opposite one another across the
frame, about 24 inches apart and placed so that none is opposite a
thwart, except for the stakes at the extreme ends of the gunwale frame,
which are spaced about a foot from their nearest neighbors and are
face-to-face, about 1½ inches apart. All the stakes are driven with
the flat face about an inch from the gunwale frame and parallel to its
outside edge. Finally two more pairs of stakes are driven at each end,
the first pair about a foot beyond the end of the gunwale frame and
1½ inches apart, the second about 6 inches beyond these and similarly
spaced. The length between the outermost stakes, measured over the
gunwale frame, is about 18½ feet. Great care is taken to line up the
last pairs of stakes with the centerline of the gunwale frame.

SECOND STAGE OF CANOE CONSTRUCTION: stakes have been removed and laid
aside, and the gunwales shown in first stage have been removed from the
building bed. The bark cover is laid out on the building bed, and the
gunwales are in place upon it, weighted down with stones. (_Sketch by
Adney_.)]
 
If the canoe is to have a slight rocker near the ends and is to be
straight over the rest of the bottom, the ends of the gunwale frame
will be blocked above the building bed so that the frame is not hogged
on the bed.
 
After the builder is satisfied with the staking, each stake is
carefully pulled up and laid to one side, off the bed but near its
hole. The weights are then removed from the gunwale frame, which is
lifted from the bed and laid aside, and the bed, if disturbed is
repaired and re-leveled.
 
The roll of birch bark is now removed from storage, perhaps in a nearby
pool where it has been placed to keep it flexible, and unrolled white
side up on the building bed. As the bark dries, it will become more and
more stiff, so it will be necessary to moisten it frequently during
construction to maintain its flexibility.
 
The bark is usually long enough, but often it is not wide enough. If
the bark is too short, it may be pieced out at this time, or later. If
it is not wide enough it is centered on the bed; the piecing out will
be done later. The gunwale frame is now laid on the bark, care being
taken to place it as nearly as possible in its former position on the
bed.
 
The bark outside the frame is then slashed from the edge to a point
close to the end of each thwart, and also to points along the frame
halfway between the thwarts, so that the edges can be turned up. While
it is being slashed, the bark cover is bent slightly, so that it is
cut under tension. Later, when the required shape can be determined,
these slashes will be made into gores, the Malecite canoes having
flush seams, not overlaps, in the topsides and bottom. If a fault is
noted along the outer edge of the bark, a slash may be placed so as to
allow the fault to be cut out in the later goring; irregularity in the
position of the cuts does no great harm to the progress of building
these canoes. The slashes are usually carried to within an inch of the
gunwales on the bed. It is not customary to slash the bark close to the
end, there the bark can usually be brought up unbroken, depending upon
the form of the end.
 
When the bark has been cut as described, it can be turned up smoothly
all around the frame so that the stake holes can be seen and a few
of the stakes can be replaced. The frame and the bark are then
realigned so that all stakes may be replaced in their holes without
difficulty. When the frame and bark are aligned, the frame is weighted
as before and the bark is turned up all around it, the stakes being
firmly driven, as this is done, in their original holes. The longest
stakes are at the ends of the frame, as the depth of the hull is to be
greatest there. The tops of each pair of opposite stakes are now tied
together with a thong of basswood or cedar bark, to hold them rigid and
upright.

method of construction, which probably originated in the early French
canoe factory at Trois Rivières, Que.]
 
After the bark is turned up around the frame, its lack of width becomes
fully apparent. At this stage, some builders fitted the additional
pieces to gain the necessary width; others did it later. The method of
piecing the bark cover and the sewing technique, however, is explained
here.
 
The bark is pieced out with regard to the danger of abrasion that would
occur when the canoe is moving through obstructions in the water, or
when it is rolled or hauled ashore and unloaded. If the bark is to be
lapped below the waterline, the thickness of the bark of both pieces
in the lap is scraped thin so a ridge will not be formed athwart the
bottom; here, however, most tribes used edge-to-edge joining. If
there are laps in the topsides, the exposed edge is toward the stern;
if in the midlength, upward toward the gunwale; and if it is in the
end the lap may be toward the bottom, because this makes it easier
to sew, and because in the ends of the canoe there is less danger of
serious abrasion. Many tribes used edge-to-edge joining everywhere
in the topsides so that the direction of lapping was not a matter of
consideration. The type of goring, whether by slash and lap or by
cutting out a ~V~-shaped gore, will, of course, have much to do with
the selection of the method of sewing to be used.
 
It is to be recalled that in canoe building no needle was used in
sewing the bark; the ends of the root strands were sharpened and used
to thread the strand through the awl holes. Much of the topside sewing
in a bark canoe was done with small strands made by splitting small
roots in half and then flattening the halves by scraping. Large root
strands quartered and prepared in the same manner, or the cores of
these, were sometimes used in heavy sewing or lashing at the gunwale or
in the ends of a canoe.
 
As noted previously, root thongs were used well water-soaked or quite
green, for they became very stiff and rather brittle as they dried
out. Once in place, however, the drying did not seem to destroy their
strength. Rawhide was also used for such sewing by some tribes.
 
The sewing was done by Indian women, if their help was available, and
the forms of stitching used in canoe building varied greatly. The root
sewing at the ends of the canoes ranged from a simple over-and-over
spiral form to elaborate and decorative styles. Long-and-short
stitching in a sequence that usually followed some formal pattern was
widely used. Among the patterns were such arrangements as one long,
four short, and one long; or two longs, two or three shorts, and two
longs; or one short, five of progressively increasing length, and then
one short; or six progressively longer followed by six progressively
shorter. Cross-stitching, employing the two ends of the sewing root as
in the lacing of a shoe was also common. Sometimes this was combined
with a straight-across double-strand pass to join the ends of the ~X~.
The harness stitch, in which both ends of the sewing root were passed
in opposite directions through the same holes, was often used, as was
the 2-thong in-and-out lacing from each side used in northwestern
canoes having plank stem-pieces.
 
If the root strand was too short to complete a seam, instead of being
spliced or knotted the end was tucked back under the last turns or
stitches, on the inside of the bark cover. In starting, the tail was
placed under the first turn of the stitch, so that it could not be
pulled through. To finish sewing with double-ended strands, as in the
harness stitch, both ends were tucked under the last turn or two.
 
Commonly two or more turns were taken through a single hole in the
bark; this might be done to clear some obstruction such as a frame head
at the gunwale, or to provide a stronger stitch, or turn, as in the
harness stitch and others, or to allow for greater spacing between awl
holes in the bark. (Since the awl blade was tapered, the size of the
hole it made in the bark could be regulated by the depth of penetration
of the blade as it was turned in the hole.)
 
The length of stitches varied with the need for strength and
watertightness. Long stitches were about I inch, short stitches from
about to ½ inch in length. The run of the grain, of course, was a
consideration in the length of stitch used.
