text: Australia Some Australian aboriginal peoples made bark canoes. They could be made only from the bark of certain trees (usually red gum or box gum) and during summer. After cutting the outline of the required size and shape, a digging stick was used to cut through the bark to the hardwood, and the bark was then slowly prised out using numerous smaller sticks. The slab of bark was held in place by branches or handwoven rope, and after separation from the tree, lowered to the ground. Small fires would then be lit on the inside of the bark to cause the bark to dry out and curl upwards, after which the ends could be pulled together and stitched with hemp and plugged with mud. It was then allowed to mature, with frequent applications of grease and ochre. The remaining tree was later dubbed a canoe tree by Europeans.
  Because of the porosity of the bark, these bark canoes did not last too long (about two years). They were mainly used for fishing or crossing rivers and lakes to avoid long journeys. They were usually propelled by punting with a long stick. Another type of bark canoe was made out of a type of stringybark gum known as Messmate stringybark (Eucalyptus obliqua), pleating the bark and tying it at each end, with a framework of cross-ties and ribs. This type was known as a pleated or tied bark canoe. Bark strips could also be sewn together to make larger canoes, known as sewn bark canoes.
