At present we are far from such a stage of progress in the history of man. The cave-dwellers were, we may be sure, in the hunting and fishing stage of civilization; and we cannot really tell, among a large proportion of their weapons, which were designed to serve against animals for the purposes of the chase, and which against their fellow-men. We can hardly distinguish among some of their weapons whether they were to be used in hunting or fishing. They had stone axes and spear-heads, and they also had what we may call harpoons. But harpoons are merely lances attached to a thong, and may be used with equal success against animals or against the larger fish, salmons or whales. These harpoons are barbed. They are made of wood and of bone. A curious and close inquiry has discovered that the bones of animals found among the human remains in the caves have been scored in such a way as to suggest that the sinews were cut from them--to be used, no doubt, as thongs to the harpoons, as lines for fishing, as threads for sewing garments, etc. The cave men had also barbed hooks--fishing-hooks we may call them; though they too may sometimes have been employed against animals or even _birds_. It is most probable that these primitive men did _not_ know the use of the bow and arrow, and that the name arrow-heads sometimes given to certain of their weapons is a misnomer; that they should be called javelin-heads. Bone awls have been found, no doubt for the sake (chiefly) of piercing the scraped skins of animals, which might afterwards be sewn together into garments: bone knives, pins, and _needles_ have also been found--the last a most important form of implement--in considerable numbers.
