Historical Algonquin society was largely hunting and fishing-based. Being primarily a hunting nation, the people emphasized mobility. They used materials that were light and easy to transport. Canoes were made of birch bark, sewed with spruce roots and rendered waterproof by the application of heated spruce resin and bear grease. During winter, toboggans were used to transport material, and people used snowshoes to get around. The women used "" (cradleboards) to carry their babies. It was built with wood and covered with an envelope made of leather or material. The baby was standing up with his feet resting on a small board. The mother would then put the "tikinàgan" on her back. This allowed the infant to look around and observe his surroundings. The child was kept close to the mother but also had much stimulation.
