CHAPTER VI THE BIRCH-BARK

How to Build a Real Birch-Bark Canoe or a Canvas Canoe on a "Birch-Bark" Frame—How to Mend a Birch-Bark

Although the Indian was the first to build these simple little boats, some of his white brothers are quite as expert in the work. But the red man can outdo his white brother in navigating the craft. The only tools required in building a canoe are a knife and awl, a draw-shave and a hammer. An Indian can do all of his work with a knife.

Several years ago canvas began to be used extensively in canoe-building, instead of birch bark, and it will eventually entirely supersede birch, although nothing can be found that bends so gracefully. There are several canvas-canoe factories in Maine, and the canoes made of canvas have both the symmetry and the durability of the birches. They are also a trifle cheaper, but if the real thing and sentiment are wanted, one should never have anything but a bark craft.

If properly handled, a good canoe will safely hold four men. Canoes intended for deep water should have considerable depth. Those intended for shoal water, such as trout-fishers use, are made as flat as possible. Up to the time when canoeing was introduced the materials for building craft of this kind could be found all along the rivers. Big birch-trees grew in countless numbers, and clear, straight cedar was quite as plentiful within a few feet of the water's edge. Now one must go miles back into the dense forests for such materials, and even then seldom does it happen that two suitable trees are found within sight of one or the other. Cedar is more difficult of the two to find.

The Tree

The tree is selected, first, for straightness; second, smoothness; third, freedom from knots or limbs; fourth, toughness of bark; fifth, small size of eyes; sixth, length (the last is not so important, as two trees can be put together), and, seventh, size (which is also not so important, as the sides can be pieced out).

Dimensions

The average length of canoe is about 19 feet over all, running, generally, from 18 to 22 feet for a boat to be used on inland waters, the sea-going canoes being larger, with relatively higher bows. The average width is about 30 inches inside, measured along the middle cross-bar; the greatest width inside is several inches below the middle cross-bar, and is several inches greater than the width measured along said cross-bar.

The measurements given below are those of a canoe 19 feet over all: 16 feet long inside, measured along the curve of the gunwale; 30 inches wide inside. The actual length inside is less than 16 feet, but the measurement along the gunwales is the most important.

Bark

Bark can be peeled when the sap is flowing or when the tree is not frozen—at any time in late spring, summer, and early fall (called summer bark); in winter during a thaw, when the tree is not frozen, and when the sap may have begun to flow.

Difference in the Bark

Summer bark peels readily, is smooth inside, of a yellow color, which turns reddish upon exposure to the sun, and is chalky-gray in very old canoes. Winter bark adheres closely, and forcibly brings up part of the inner bark, which on exposure turns dark red. This rough surface may be moistened and scraped away. All winter-bark canoes must be thus scraped and made smooth. Sometimes the dark red is left in the form of a decorative pattern extending around the upper edge of the canoe, the rest of the surface being scraped smooth.

Process of Peeling

The tree should be cut down so that the bark can be removed more easily.

A log called a skid (Fig. 79) is laid on the ground a few feet from the base of the tree, which will keep the butt of the tree off the ground when the tree is felled. The limbs at the top will keep the other end off the ground. A space is cleared of bushes and obstructions where the tree is to fall.

After the tree has been cut down, a cut is made in a straight line (A, B, Fig. 79), splitting the bark from top to bottom, and a ring cut at A and B (Fig. 79). When sap is flowing, the bark is readily removed; but in winter the edges of the cut are raised with a knife, and a thin, pliant hard-wood knife or "spud" is pushed around under the bark.

Toasting

After the bark has dropped upon the ground the inside surface is warmed with a torch, which softens and straightens it out flat. The torch is made of a bundle of birch bark held in a split stick (Fig. 81).

It is then rolled up like a carpet, with inside surface out, and tightly bound, generally with cedar bark when the latter can be procured (Fig. 80).

If the tree is long enough, a piece is taken off at least nineteen feet in length, so that the ends of the canoe may not be pieced out. A few shorter pieces are wrapped up with the bundle for piecing out the sides.

The Roll

is taken on the back in an upright position, and is carried by a broad band of cedar bark, passing under the lower end of the roll and around in front of the breast and shoulders (Fig. 82).
drawing
Fig. 82.—Mode of carrying roll.

Effects of Heat

It is laid where the sun will not shine on it and harden it. The first effect of heat is to make it pliant. Long exposure to heat or to dry atmosphere makes it hard and brittle.

The Woodwork

is as follows:

Five cross-bars of rock-maple (Figs. 83, 85, and 91). All the rest is of white cedar, taken from the heart. The sap-wood absorbs water, and would make the canoe too heavy, so it is rejected. The wood requires to be straight and clear, and it is best to use perfectly green wood for the ribs.

Two strips 16½ feet long, 1½ inch square, tapering toward either end, the ends being notched (Fig. 83 A) is a section of the 16½ foot strip. Each strip is mortised for the cross-bars (see Fig. 85). The lower outside edge is bevelled off to receive the ends of the ribs.

The dimensions of the cross-bars (Fig. 85) are 12 x 2 x ½ inch, 22½ x 2 x ¾ inch, and 30 x 2 x 7/8 inch. The cross-bars are placed in position, and the ends of the gunwales are tied with spruce roots after being nailed together to prevent splitting. Each bar is held in place by a peg of hard wood.

For stitching and wrapping, long, slender roots of spruce, or sometimes of elm, are peeled and split in two. Black ash splits are rarely used except for repairing (Figs. 86, 87, 88).

Next we need (B, Fig. 83) two strips 1 or 1¼ inch by ½ inch, a little over 19 feet long, to go outside of gunwales, and (C, Fig. 83) two top strips, same length, 2 inches wide in middle, tapering to 1 inch at either end, 1½ inch thick.

Ribs

About fifty in number (Figs. 91, 92) are split with the grain (F, Fig. 92), so that the heart side of the wood will be on the inner side when the rib is bent. The wood bends better this way. They must be perfectly straight-grained and free from knots. Ribs for the middle are four inches wide, ribs for the ends about three inches wide (Fig. 91 and G, Fig. 92), and are whittled down to a scant half an inch (Fig. 93). Green wood is generally used, and before it has had any time to season. The ribs may be softened by pouring hot water on them, and should be bent in pairs to prevent breaking (Fig. 90). They are held in shape by a band of cedar bark passed around outside.

The ribs are of importance in the shaping of the canoe. The sides bulge out (Figs. 91, 92). The shape of the ribs determines the depth and stability of the canoe.

Lining Strips

Other strips, an eighth of an inch thick, are carefully whittled out, with straight edges. They are a little over eight feet long, and are designed to be laid inside on the bark, edge to edge, between the bark and the ribs. These strips lap an inch or two where they meet, in the middle of the canoe, and are wider here than at the ends, owing to the greater circumference of the canoe in the middle.

Seasoning

All the timber is carefully tied up before building and laid away. The ribs are allowed to season perfectly, so that they will keep their shape and not spring back.

The Bed

Next the bed is prepared on a level spot, if possible shaded from the sun. A space is levelled about three and a half feet wide and a little longer than the canoe. The surface is made perfectly smooth. The middle is one or two inches higher than either end.

Building

The frame is laid exactly in the middle of the bed. A small post is driven in the ground (Fig. 94), on which each end of the frame will rest. Stakes, two or three feet long and about two inches in diameter, are whittled flat on one side, and are driven with the flat side toward the frame at the following points, leaving a space of about a quarter of an inch between the stake and the frame (Fig. 94): One stake an inch or two on either side of each cross-bar, and another stake half way between each cross-bar. This makes eleven stakes on each side of the frame. Twelve additional stakes are driven as follows: One pair facing each other, at the end of the frame; another pair, an inch apart, about six inches from the last pair, measuring toward the ends of the canoe; and another pair, an inch apart, a foot from these. These last stakes will be nine and a half feet from the middle of the frame, and nineteen feet from the corresponding stakes at the other end. Next, these stakes are all taken up, and the frame laid aside.

To Soften the Bark

Next the bark is unrolled. If it has laid until it has become a little hardened, it is placed in the river or stream for a day or two. It is spread out flat, and laid upon the bed with the gray or outside surface up. The inside surface is placed downward, and becomes the outside of the canoe.

The frame is replaced upon the bark, so that it will be at the same distance from each side and end of the bed that it was before. At each cross-bar boards are laid across the frame, and heavy stones are laid upon them to keep the frame solid and immovable upon the bark (Fig. 85, C). The edges of the bark are next bent up in a perpendicular position, and in order that it may bend smoothly slits are made in the bark in an outward direction, at right angles to the frame. A cut is made close to the end of each cross-bar, and one half way between each bar, which is generally sufficient to allow the bark to be bent up smoothly. As the bark is bent up, the large stakes are slipped back in the holes which they occupied before, and the tops of each opposite pair are connected with a strip of cedar bark which keeps the stakes perfectly perpendicular. At each end it is necessary to take out a small triangular piece or gore, so that the edges may come together without overlapping.

Next twenty-two pieces of cedar, one to two feet long, and about ½ or ¾ inch thick, are split out, and whittled thin and flat at one end. This sharpened edge is inserted between the outside edge of the frame and the bent-up bark, opposite each large stake. The other end of the chisel-shaped piece is tightly tied to the large stake outside. By means of the large outside stake and the inside "stake," so-called, the bark is held in a perfectly upright position; and in order to keep the bent-up part more perfectly flat and smooth, the strips of cedar are pushed in lengthwise between the stakes and the bark, on each side of the bark, as shown in sectional views (Fig. 85, C, D).

Sometimes, in place of having temporary strips to go on outside of the bark, the long outside strip (B, Fig. 83), is slipped in place instead.

It may now be seen if the bark is not wide enough. If it is not, the sides must be pieced out with a narrow piece, cut in such a way that the eyes in the bark will run in the same direction as those of the large piece.

As a general rule, from the middle to the next bar the strip for piecing is placed on the inside of the large piece, whose upper edge has previously been trimmed straight, and the two are sewed together by the stitch shown in Fig. 86, the spruce root being passed over another root laid along the trimmed-off edge of the large piece of bark to prevent the stitches from tearing out. From the second bar to the end of the canoe, or as far as may be necessary, the strip is placed outside the large piece, and from the second to the end bar is sewed as in Fig. 87, and from the end bar to the end of the canoe is stitched as in Fig. 88.

Next, the weights are taken off the frame, which is raised up as follows, the bark remaining flat on the bed as before:

A post eight inches long is set up under each end of middle cross-bar (Fig. 85, D), one end resting on the bark and the other end supporting either end of the middle cross-bar. Another post, nine inches long, is similarly placed under each end of the next cross-bar. Another, twelve inches long, is placed under each end of the end cross-bar; and another, sixteen and a half or seventeen inches, supports each end of the frame.

As the posts are placed under each cross-bar, the weights are replaced; and as these posts are higher at the ends than in the middle, the proper curve is obtained for the gunwales. The temporary strips, that have been placed outside the bent-up portion of the bark, are removed, and the long outside strip before mentioned (B, Fig. 83) is slipped in place between the outside stakes and the bark. This strip is next nailed to the frame with wrought-iron nails that pass through the bark and are clinched on the inside. This outside strip has taken exactly the curve of the frame, but its upper edge, before nailing, was raised so as to be out an eighth of an inch (or the thickness of the bark) higher than the top surface of the frame, so that when the edges of the bark have been bent down, and tacked flat to the frame, a level surface will be presented, upon which the wide top strip will eventually be nailed. Formerly the outer strip was bound to the frame with roots every few inches, but now it is nailed.

The cross-bars are now lashed to the frame, having previously been held only by a peg. The roots are passed through holes in the end of the bars, around the outside strip (see right-hand side of Fig. 85). A two-inch piece of the bark, which has been tacked down upon the frame, is removed at the ends by the cross-bars, where the spruce roots are to pass around, and the outside strip is cut away to a corresponding extent, so that the roots, when wrapped around, will be flush with the surface above.

All the stakes are now removed, and laid away to be ready for the next canoe that may be built, and the canoe taken upside down upon two horses or benches, that will keep the craft clear of the ground.

The shape of the bow is now marked out, either by the eye or with mechanical aid, according to the following rule: An arc of a circle, with a radius of seventeen inches, is described (Fig. 95) having as a centre a point shown in diagram. The bark is then cut away to this line.

Bow-piece

To stiffen the bow, a bow-piece of cedar, nearly three feet long (Fig. 96), an inch and a half wide, and half an inch thick on one edge, bevelled and rounded off toward the other edge, is needed. To facilitate bending edgeways it is split into four or five sections (as in Fig. 98) for about thirty inches. The end that remains unsplit is notched on its thicker edge (Fig. 96) to receive the lower end of an oval cedar board (Fig. 97) that is placed upright in the bow underneath the tip of the frame. It is bent to correspond with the curve of the boat, with the thin edge toward the outside of the circle, and wrapped with twine, so that it will keep its shape. The bow-piece is placed between the edges of the bark, which are then sewed together by an over-and-over stitch, which passes through the bow-piece.

A pitch is prepared of rosin and grease, in such proportions that it will neither readily crack in cold water nor melt in the sun. One or the other ingredient is added until by test it is found just right.

Patching and Pitching

The canoe is now placed on the ground, right side up, and all holes are covered on the inside with thin birch bark that is pasted down with hot pitch. A strip of cloth is saturated with hot pitch, and pressed into the cracks on either side of the bow-piece inside, between the bark and the bow-piece (Fig. 99).

drawings
Figs. 97-100.—Show details of canoe bow.

The thin longitudinal strips are next laid in position, edge to edge, lapping several inches by the middle; they are whittled thin here so as to lap evenly.

The ribs are next tightly driven in place, commencing at the small end ones and working toward the middle. The end ribs may be two or three inches apart, being closer toward the middle, where, in many cases, they touch. Usually, they are about half an inch apart in the middle. Each rib is driven into place with a square-ended stick and a mallet.

The ends are stuffed with shavings (Fig. 100 and "Section" Fig. 100½), and an oval cedar board is put in the place formerly occupied by the post that supported the end of the frame. The lower end rests in the notch of the bow-piece, while the upper is cut with two shoulders that fit underneath each side of the frame; Fig. 97 shows the cedar board.

The top strip is next nailed on to the frame. Almost always a piece of bark, a foot or more long, and nine or ten inches wide, is bent and slipped under, between both top and side strips and the bark. The ends of this piece hang down about three inches below the side strips. The loose ends of the strips are bound together, as in diagram, and the projecting tips of both strips and bow-piece are trimmed off close.

Next the canoe is turned upside down. If winter bark has been used, the surface is moistened and the roughness scraped off with a knife. Generally the red rough surface is left in the form of a decorative pattern several inches wide around the upper edge (Fig. 95). Sometimes the maker's name and date are left in this way.

Finally, a strip of stout canvas, three or four inches wide, is dipped in the melted pitch and laid on the stitching at the ends, extending up sufficiently far above the water-line. All cracks and seams are covered with pitch, laid on with a small wooden paddle. While still soft, a wet finger or the palm of the hand is rubbed over the pitch to smooth it down before it hardens.

Leaks

Water is placed inside, and the leaky places marked, to be stopped when dry. A can of rosin is usually carried in the canoe, and when a leak occurs, the canoe is taken out of the water, the leak discovered by sucking, the place dried with a torch of wood or birch bark, and the pitch applied.

drawing
Fig. 101½.—From photograph of Indian building a birch-bark canoe.

Paddles are made of rock maple, and sometimes of birch and even cedar. Bow paddles are usually longer and narrower in the blade than stern paddles (Fig. 101).

Bottom Protection

Sometimes the canoe is shod with "shoes," or strips of cedar, laid lengthwise and tied to the outside of the bark with ash splits that pass through holes in the cedar shoes, and are brought up around the sides of the canoe and tied to each cross-bar. This protects the bottom of the boat from the sharp rocks that abound in some rapid streams.

All canoes are of the general shape of the one described, though this is considerably varied in different localities, some being built with high rolling bows, some slender, some wider, some nearly straight on the bottom, others decidedly curved.

Besides the two paddles the canoe should carry a pole ten feet long, made of a slender spruce, whittled so as to be about one and three-fourths inch in diameter in the middle and smaller at either end, and having at one end either a ring and a spike or else a pointed cap of iron. The pole is used for propelling the canoe up swift streams. This, says Tappan Adney, "is absolutely indispensable." The person using the pole stands in one end, or nearer the middle if alone, and pushes the canoe along close to the bank, so as to take advantage of the eddies, guiding the canoe with one motion, only to be learned by practice, and keeping the pole usually on the side next the bank. Where the streams have rocky and pebbly bottoms poling is easy, but in muddy or soft bottoms it is tiresome work; muddy bottoms, however, are not usually found in rapid waters.

A Canvas Canoe

can be made by substituting canvas in the place of birch bark; and if it is kept well painted it makes not only a durable but a very beautiful boat. The writer once owned a canvas canoe that was at least fifteen years old and still in good condition.

About six yards of ten-ounce cotton canvas, fifty inches wide, will be sufficient to cover a canoe, and it will require two papers of four-ounce copper tacks to secure the canvas on the frame.

The boat should be placed, deck down, upon two "horses" or wooden supports, such as you see carpenters and builders use.

Fold the canvas lengthwise, so as to find the centre, then tack the centre of one end of the cloth to top of bow-piece, or stem, using two or three tacks to hold it securely. Stretch the cloth the length of the boat, pull it taut, with the centre line of the canvas over the keel line of the canoe, and tack the centre of the other end of the cloth to the top of the stern-piece.

If care has been taken thus far, an equal portion of the covering will lap the gunwale on each side of the boat.

Begin amidships and drive the tacks, about two inches apart, along the gunwale and an inch below the deck (on the outside). Tack about two feet on one side, pull the cloth tightly across, and tack it about three feet on the other side. Continue to alternate, tacking on one side and then the other, until finished.

With the hands and fingers knead the cloth so as to thicken or "full" it where it would otherwise wrinkle, and it will be possible to stretch the canvas without cutting it over the frame.

The cloth that projects beyond the gunwale may be used for the deck, or it may be cut off after bringing it over and tacking upon the inside of the gunwale, leaving the canoe open like a birch-bark.

To Paddle a Canoe

No one can expect to learn to paddle a canoe from a book, however explicit the directions may be. There is only one way to learn to swim and that is by going into the water and trying it, and the only proper way to learn to paddle a canoe is to paddle one until you catch the knack.

In the ordinary canoe, to be found at the summer watering places, there are cane seats and they are always too high for safety. A top load on any sort of a boat is always dangerous, and every real canoeist seats his passengers on the bottom of the boat and kneels on the bottom himself while paddling. Of course, one's knees will feel more comfortable if there is some sort of a cushion under them, and a passenger will be less liable to get wet if he has a pneumatic cushion on which to sit. No expert canoeist paddles alternately first on the one side, and then on the other; on the contrary, he takes pride in his ability to keep his paddle continuously on either side that suits his convenience.

The Indians of the North Woods are probably the best paddlers, and from them we can take points in the art. It is from them we first learned the use of the canoe, for our open canvas canoes of to-day are practically modelled on the lines of the old birch-barks.

If the canoe tends to swerve it is because the stroke was not correct. Only a duffer steers with his paddle after the stroke is over. The left hand now moves forward, the right swinging out and back, moving paddle forward horizontally.

Position of right wrist shows that blade has the opposite slant to that shown in the straightaway stroke—i. e., the near face of blade is turned inward. Blade leaves water with outer edge up. Wake of canoe shows sharpness of turn.

Fig. 104c.—Turning to left. The last motion of a stroke in which the paddle is swept close to the canoe with the blade turned much farther outward than in the straightaway stroke. At end of stroke blade is given an outward sweep and leaves the water with the inner edge up. This is not a steering or dragging motion. It is a powerful sweep of the paddle. Note swirl in wake of canoe showing sharp turn.]

When you are standing upright and your paddle is in front of you with the blade upon the ground, the handle should reach to your eye-brows. (See Figs. 101, 102, 103, etc.)

Kneel with the paddle across the canoe and not farther forward than the knees. Then dip the blade edgewise (not point first) by raising the upper hand without bending the elbow. Swing the paddle back, keeping it close to the canoe, and give a little twist to the upper wrist to set the paddle at the proper angle shown in the photos. The exact angle depends upon the trim of the boat, the wind, etc., and must be such that the canoe does not swerve at any part of the stroke, but travels straight ahead. The lower arm acts mainly as a fulcrum and does not move back and forth more than a foot. The power comes from the upper arm and shoulder, and the body bends forward as the weight is thrown on the paddle. The stroke continues until the paddle slides out of the water endwise, flat on the surface. Then for recovery the blade is brought forward by a swing from the shoulder, not lifting it vertically, but swinging it horizontally with the blade parallel to the water and the upper hand low. When it reaches a point opposite the knee it is slid into the water again, edgewise, for another stroke. The motion is a more or less rotary one, like stirring cake, not a simple movement back and forth.

To Carry a Canoe

To pick up a canoe and carry it requires not only the knack but also muscle, and no undeveloped boy should make the attempt, as he might strain himself, with serious results. But there are plenty of young men—good, husky fellows—who can learn to do this without any danger of injury if they are taught how to lift by a competent physical instructor.

Fig. 106. Fig. 105. Fig. 107. Fig. 108. Fig. 109.

To pick up a canoe for a "carry," stoop over and grasp the middle brace with the right arm extended, and a short hold with the left hand, as shown in Fig. 105.

When you have a secure hold, hoist the canoe up on your legs, as shown in Fig. 106. Without stopping the motion give her another boost, until you have the canoe with the upper side above your head, as in Fig. 107. In the diagram the paddles are not spread apart as far as they should be. If the paddles are too close together a fall may break ones neck.

drawing
Fig. 110.—Northern Quebec Indians crossing the "ladder portage."

Now turn the canoe over your head and slide your head between the paddles (which are lashed to the spreaders, as shown in Fig. 105), and twist your body around as you let the canoe settle down over your head (Fig. 108). If you have a sweater or a coat, it will help your shoulders by making a roll of it to serve as a pad under the paddles, as in Fig. 109. I have seen an Indian carry a canoe in this manner on a dog-trot over a five-mile portage without resting. I also have seen Indians carry canoes over mountains, crossing by the celebrated Ladder Portage in western Quebec, where the only means of scaling a cliff is by ascending a ladder made of notched logs. For real canoe work it is necessary that a man should know how to carry his craft across country from one body of water to another. All through the Lakelands of Canada, and also the Lake St. John district, up to Hudson Bay itself, the only trails are by water, with portage across from one stream or lake to the other.
