penetrated an animal, and remain in the wound. There were three main kinds of harpoon that the Aleuts used: a simple harpoon, with a head that kept its original position in the animal after striking, a compound (toggle-head) harpoon in which the head took a horizontal position in the animal after penetration, and the throwing-lance used to kill large animals. The simple Aleut harpoon consisted of four main parts: the wooden shaft, the bone foreshaft, and the bonehead (tip) with barbs pointed backward. The barbed head was loosely fitted into the socket of the foreshaft so that when the animal was stabbed, it pulled the head away from the rest of the harpoon. The sharp barbs penetrated with ease, but could not be pulled out. The bone tip is fastened to a length of braided twine meanwhile; the hunter held the other end of the twine in his hand. The compound harpoon was the most prevalent weapon of the Aleut people. Also known as the toggle-head spear, it was about the same size as the simple harpoon and used to hunt the same animals, however, this harpoon provided a more efficient and lethal weapon. This harpoon separated into four parts. The longest part was the shaft with the thicker stalk closer to the tip of the harpoon. The shaft was fitted into the socket of the fore shaft and a bone ring was then placed over the joint to hold the two pieces together, as well as, protecting the wooden shaft from splitting. Connected to the fore shaft of the harpoon is the toggle head spear tip. This tip was made of two sub shafts that break apart on impact with an animal. The upper sub shaft held the razor stone head and attached to the lower sub shaft with a small braided twine loop. Once the tip penetrates the animal the upper sub head broke off from the rest of the shaft, however, since it was still connected with the braided loop it rotated the head into a horizontal position inside the animal's body so that it could not get away from the hunter. The throwing lance may be distinguished from a harpoon because all its pieces are fixed and immovable. A lance was a weapon of war and it was also used to kill large marine animals after it has already been harpooned. The throwing lance usually consisted
