The use of drills as war arrow-points brings up an interesting subject, and would indicate that many of the things that we have named according to our own fancy were doubtless made use of by the Indians for totally different purposes from those to which we have assigned them. Drills—the smaller kind—certainly possess great power of penetration, and when discharged may have entered to a greater depth. The broader points, however, would produce a more tearing wound and cause greater flow of blood. Broad points were more in evidence as hunting-points, for the obvious reason that if the deer or other game lost blood freely, its capture became more certain. Professor Henry, of the Smithsonian, made a collection of buffalo and human bones, in which arrow-heads were embedded. In several of the buffalo ribs and scapulæ were arrow-points which had been shot _through_ the animal, piercing the bone on the inner side. Wilson says that such specimens “illustrate the force with which an arrow can be shot by the bow, and, because of its initial velocity, there is no comminution of the bones. The edges around the wounds are not fractured or fissured on either side; there are no splinters made by the arrow on entering or leaving. This is due to the same principle that a pistol-ball fired at short range passes through a pane of glass without shattering it.” A paper by W. Thornton Parker, M.D., describes the arrow and its mode of manufacture, and magnifies the malignity of arrow-wounds. The author explains the apocryphal difference between hunting- and war-arrows, saying:— “The head of the war-arrow is shorter and broader than that of the hunting-arrow, and is attached to the shaft at right angles with the slot which fits the bow-string, the object being to allow the arrow in flight more readily to pass between the human ribs, while the head of the hunting-arrow, which is long and narrow, is attached perpendicularly to the slot, to allow it to pass readily between the ribs of the running buffalo. “Ashhurst wrote an extensive article on arrow-wounds. He takes a favorable view of the curability of arrow-wounds, which is borne out by the cases cited, and says: ‘Those penetrating the chest and wounding the lung, although serious, are by no means mortal.... If the patient survives the hemorrhage, the prognosis is favorable, for the consecutive inflammation is trifling and requires no treatment beyond placing the patient at rest and affording a supply of pure warm air.’ [Illustration: FIG. 101.
