What the first immigrants brought with them in culture was rudimentary. They kept dogs, but no other domesticated animal. They were not yet agricultural, and subsisted on what they wrested from nature. They knew something of weaving baskets and mats; clothed and housed themselves; probably had harpoons and possibly bows; made fire with the drill; cut with flint knives; and believed in magic, spirits, and the perpetuity of the soul.
