Two other points remain to be noticed. One is that divination by cracks in a deer's roasted shoulder blade, a process referred to more than once in the Records and the Chronicles, was a practice of the Chinese, who seem to have borrowed it from the Mongolians; the other, that the sounding arrow (nari-kabura) was an invention of the Huns, and came to Japan through China. It had holes in the head, and the air passing through these produced a humming sound. As for the Chronicles, they are permeated by Chinese influence throughout. The adoption of the Chinese sexagenary cycle is not unnatural, but again and again speeches made by Chinese sovereigns and sages are put into the mouths of Japanese monarchs as original utterances, so that without the Records for purposes of reference and comparison, even the small measure of solid ground that can be constructed would be cut from under the student's feet.

CHAPTER IV
RATIONALIZATION
GEOGRAPHICAL FEATURES
THE southwestern extremity of the main island of Japan is embraced by two large islands, Kyushu and Shikoku, the former lying on the west of the latter and being, in effect, the southern link of the island chain which constitutes the empire of Japan. Sweeping northward from Formosa and the Philippines is a strong current known as the Kuro-shio (Black Tide), a name derived from the deep indigo colour of the water. This tide, on reaching the vicinity of Kyushu, is deflected to the east, and passing along the southern coast of Kyushu and the Kii promontory, takes its way into the Pacific. Evidently boats carried on the bosom of the Kuro-shio would be likely to make the shore of Japan at one of three points, namely, the south, or southeast, of Kyushu, the south of Shikoku or the Kii promontory.
Now, according to the Records, the first place "begotten" by Izanagi and Izanami was an island called Awa, supposed to be in the vicinity of Awaji. The latter is a long, narrow island stretching from the northeast of Shikoku towards the shore of the main island—which it approaches very closely at the Strait of Yura—and forming what may be called a gate, closing the eastern entrance to the Inland Sea. After the island of Awa, the producing couple gave birth to Awaji and subsequently to Shikoku, which is described as an island having four faces, namely, the provinces of Awa, Iyo, Tosa, and Sanuki.
Rejecting the obviously allegorical phantasy of "procreation," we may reasonably suppose ourselves to be here in the presence of an emigration from the South Seas or from southern China, which debarks on the coast of Awaji and thence crosses to Shikoku. Thereafter, the immigrants touch at a triplet of small islands, described as "in the offing," and thence cross to Kyushu, known at the time as Tsukushi. This large island is described in the Records as having, like Shikoku, one body and four faces, and part of it was inhabited by Kumaso, of whom much is heard in Japanese history. From Kyushu the invaders pass to the islands of Iki and Tsushima, which lie between Kyushu and Korea, and thereafter they sail northward along the coast of the main island of Japan until they reach the island of Sado.
All this—and the order of advance follows exactly the procreation sequence given in the Records—lends itself easily to the supposition of a party of immigrants coming originally from the south, voyaging in a tentative manner round the country described by them, and establishing themselves primarily on its outlying islands.
