_Second_ came the hunting Spear, used originally on fish lying in pools, small of size but of depth sufficient to prevent hand fishing, and then, later, on fish elsewhere in a river. On the latter, especially in the case of the salmon—in Pliny’s day still abundant in Aquitania, which comprised the Loire and many Palæolithic _cavernes_—the weapon, even if as bident or trident it had added unto itself a prong or two, would frequently be found ineffective, owing to lack of prehensility. Hence came about a modification, perhaps due either to the happy chance of a spear on which a point or thorn had inadvertently been left, or to the inventive faculty of some Troglodyte Hardy. We later reach a Spear Harpoon with barbs on one side only, whence “line upon line,” or rather barb upon barb, we attain unto the later type, which had a barbed head so socketed as to come free from the shaft (when the quarry has been struck) but made fast to the head by a line for retrieving the fish. In due, if differing, gradation we ultimately attain either unto the existing device of the aboriginal Tsuŷ Hwan of Formosa, an arrow shaped like a trident shot from but attached to a bow, or unto _le dernier cri_, our whaling Harpoon shot from a gun.[73] _Third_ comes fishing with a line of some sort. This was devised doubtless by some hungry but perforce merely meditative Magdalenian observing how dropped morsels were seized by fish in a pool, whose depth or environment set at naught both his hand and his spear. The problem how to reach and how to land them was eventually solved by the method—happily christened by Sheringham, “Entanglement by Appetite”—of fastening a gorge through or a thorn holding some kind of bait to an animal sinew, a wythe, or a hardened thong of one of the whip-like _algæ_. This wythe or what not in the procession of the ages was (according to Pepys) to betaper itself into the first English catgut line of 1667, and (according to _The Compleat Fisherman_, London, 1724) into the first silkworm line, and eventually into telerana and similar tenuities of our day. “Entanglement by Appetite,” of which a primitive form exists among the Fuegians,[74] did literally “line upon line,” almost wythe upon wythe multiply its seed, if not quite like the sand of the sea, yet freely. Proofs of this fecundity exist in the varying and world-wide forms of its issue. A strong family likeness enables us roughly to divide these descendants into two classes. The first (A) where (to quote our leading law case) “the human element” is absent, as in night lining, or in “trimmering,” or in its distant and nowadays probably illegal connection, the method of live-baiting for pike with the aid of a goose or a duck, as set forth by T. Barker with his customary gusto.[75]
