The last figure represents the head of the common Saw-fish, in which a vast number of flat and sharply-edged teeth are set upon the blade-like head. The fish has been observed to use this weapon just as the Mangaian uses his sword-spear. It dashes among a shoal of fish, sweeps its head violently backwards and forwards, and then, after they have dispersed, picks up at its leisure the dead and disabled. THE SPEAR AND THE DAGGER. It is tolerably evident that the invention of the spear and dagger must have been nearly, if not quite, contemporaneous with that of the club. I place these weapons together because there is great difficulty in assigning to either of them the precedence, the spear being but a more or less elongated dagger, and the dagger a shortened spear. As a good example of this fact, I have in my collection a number of spears and daggers belonging to the Fan tribe of Western Africa. In every case the weapons correspond so closely with each other, that if the daggers were attached to shafts they would exactly resemble the spears, and if the spears were cut off within a few inches of the head, they would be taken for daggers. I may here mention that as this part of the subject merely involves the employment of a pointed or thrusting weapon, instead of the club or sword, both of which are used for striking, the question of poison, barbs, and sheaths will be treated on another page. The primary origin of the Spear is probably the thorn, as a savage who had been wounded by a thorn would easily pass to the conclusion that a thorn of larger size would enable him to kill an enemy in war, or an animal in hunting. Anything of sufficient dimensions, which either possessed a natural point or could be sharpened into a point, would be available for the purpose of the hunter or warrior. Accordingly we find that such objects as the beak of the heron or stork, the sharp hind-claw of the kangaroo, the bone of the sting-ray, the beak of the sword-fish, and many similar objects, are employed for the heads of spears, or used simply as daggers. As to artificial spears, nothing is easier than to scrape a stick to a point, and then, if needful, to harden it in the fire. This is, indeed, one of the commonest forms of primitive spears, and I have in my collection many examples of such weapons. Another simple form of this weapon is that which is made by cutting a stick or similar object diagonally. Hollow rods--such, for example, as the bamboo--are the best for this purpose. I have now before me a cast of a most interesting weapon discovered by Colonel Lane Fox. It is the head of a spear, and is formed from part of the leg-bone of a sheep. At one end there is a simple round hole, which acted as a socket for the reception of the shaft, and the other end is cut away diagonally, so as to leave a tolerably sharp point.
