BWhy

The island is a hundred miles long. On foot, through forest, its far end is a fortnight away. By water it is a few days. A canoe also reaches fishing grounds beyond the rocks, and carries loads no one could carry on their back.

CYou need

  • A straight, sound tree of light wood that resists rot: cedar, tulip tree, cottonwood or lime. As thick as a person's chest is high when it lies on the ground, and four body lengths long.
  • Stone axes (02.08), adzes (02.09), fire (01.08) and wet clay
  • Rope (02.11), poles, and two light logs for the float
  • Split boards for paddles

DSteps

  1. Fell the tree with fire and axe together. Pack a collar of wet clay round the trunk at knee height. Burn a ring below the clay with a small fire, chop out the char, and burn again. It takes a day.
  2. Cut it to length the same way. Roll it to the water on rollers and float it. Mark the side that floats uppermost: that is the top. The heavy side becomes the bottom.
  3. Haul it out and prop it level, top side up. Adze the top flat along its whole length.
  4. Shape the outside first: a long tapering bow, a shorter stern, a slightly flattened bottom.
  5. Hollow it with fire, exactly as for a trough. Lay wet clay along both edges of the flat top to protect the sides. Burn, chop out the char with adzes, and burn again. Work from both ends toward the middle.
  6. Leave the sides two fingers thick and the bottom three. Check often by tapping and by feeling with a hand inside and a hand outside. Leave the bow and stern solid for a forearm.
  7. Leave two ridges of wood across the inside as you go, or lash in two poles later, to keep the sides from springing in. They are also the seats.
  8. Scrape the inside clean. Rub the whole hull with fat, and keep it shaded and damp until launch, so that it does not crack.
  9. A round log rolls over in the sea. Fit a float: lash two poles across the canoe, reaching out a body length to one side, and lash a light pointed log under their ends, lying parallel to the hull. Use rope, and tighten every lashing wet.
  10. Paddles: adze a split board to a blade a hand-span wide and a forearm long, on a shaft that reaches from the ground to the chin. Make one for each person and a spare.
  11. Test it loaded, in water no deeper than the waist, before anyone takes it past the rocks.

EIt worked if

  • With three people and their own weight again in cargo, a hand-span of side still shows above the water.
  • A person can climb in from deep water without turning it over.

FWhat goes wrong

  • It cracks along the grain. It dried in the sun. Keep it wet and greased; fill a crack with pitch or bitumen and lash across it.
  • The fire burns through the side. The clay dried. Assign one person to nothing but watching the clay.
  • It lists to one side. More wood was left on that side. Adze it out and try again.
  • It rolls over. No float, or the float is too close. Set it further out.

GSafety

  • Nobody goes out alone, and nobody goes beyond swimming distance of the shore until the canoe has been turned over and righted on purpose, in the shallows, by its own crew.
  • Tie the paddles and the bailer to the hull.

HIn the story

For Tane this is not a boat. It is the proof that the sea is a road, as it was for his ancestors. He works on it from first light, and sleeps beside it. Bjorn, who has built boats from sawn planks all his life, learns to build one with fire, and says it is the best work he has done. On the thirty-eighth day it floats level, and Tane paddles it out past the rocks alone, against his own rule. Adam says nothing. He is waiting on the beach when Tane comes back.
