Ballista*, or Demon's Head. — Algonkin tradition affirms that in ancient times, during the fierce wars which the Indians carried on, they constructed a very formidable instrument of attack, by sewing up a large round boulder in a new skin. To this a long handle was tied. When the skin dried, it became very tight around the stone, and, after being painted with devices, assumed the appearance and character of a solid globe upon a pole. This formidable instrument was borne by several warriors, who acted as ballisters. Plunged upon a boat or canoe, it was capable of sinking it. Brought down among a group of men on a sudden, it produced consternation and death.
