No information is obtainable as to the nature of the boats used in very early times, but it may reasonably be inferred that the Yamato and other immigrant races possessed craft of some capacity. Several names of boats are incidentally mentioned. They evidently refer to the speed of the craft--as bird-boat (tori-fune), pigeon-boat (hato-fune)--or to the material employed, as "rock-camphor boat" (iwa-kusu-bune). "The presence of neolithic remains on the islands around Japan proves that the boats of the primitive people were large enough to traverse fifty miles, or more, of open sea."* Only one distinct reference to sailing occurs, however, in the ancient annals. On the occasion of the alleged expedition to Korea (A.D. 200) under the Empress Jingo, the Chronicles say, "Sail was set from the harbour of Wani." At a date nearly three centuries earlier, there appears to have been a marked deficiency of coasting vessels, for the Chronicles quote an Imperial decree issued B.C. 81, which says: "Ships are of cardinal importance to the Empire. At present the people of the coast, not having ships, suffer grievously by land transport. Therefore let every province be caused to have ships built;"* and it is related that, a few months later, the building of ships was begun. Again, in A.D. 274, a vessel (the Karano) one hundred feet in length, was constructed in the province of Izu, and twenty-six years later, according to the Chronicles, the Emperor issued this order: "The Government ship named Karano was sent as tribute by the Lord of Izu. It is rotten and unfit for use. It has, however, been in the Government use for a long time, and its services should not be forgotten. Shall we not keep the name of that ship from being lost and hand it down to after ages?" The Karano was then broken and her timbers being employed as firewood for roasting salt, the latter was given to the various provinces, which, in return, were caused to build ships for the State, the result being a fleet of five hundred vessels. *Aston's Nihongi. It would seem that there was always an abundance of fishing-boats, for fishing by traps, hooks, and nets was industriously carried on. A passage in the Records speaks of a thousand-fathom rope of paper-mulberry which was used to draw the net in perch fishing. Spearing was also practised by fishermen, and in the rivers cormorants were used just as they are to-day. MARRIAGE
