It is not perhaps difficult to reconstruct in imagination the landscape of Japan in pre-Buddhistic days. Certainly we may, with some accuracy, draw a contrast between the appearance of the face of the earth then and now. Supposing that there were as many as a million or two of souls in the Japanese Archipelago of the sixth century--the same area which in the nineteenth century contains over forty-one millions--we can imagine only here and there patches of cultivated fields, or terraced gullies. There were no roads except paths or trails. The horse was probably yet a curiosity to the aborigines, though well known to the sons of the gods. Sheep and goats then, as now, were unknown. The cow and the ox were in the land, but not numerous.[2] In architecture there was probably little but the primeval hut. Tools were of the rudest description; yet it is evident that the primitive Japanese were able to work iron and apply it to many uses. There were other metals, though the tell-tale etymology of their names in Japanese metallurgy, as in so many other lines of industry and articles of daily use, points to a Chinese origin. It is the almost incredible fact that the Japanese man or woman wore on the person neither gold nor silver jewelry. In later times, decoration was added to the sword hilt and pins were thrust in the hair. Possibly a prejudice against metal touching the skin, such as exists in Korea, may account for this absence of jewelry, though silver was not discovered until A.D. 675, or gold until A.D. 749. The primitive Japanese, however, did wear ornaments of ground and polished stone, and these so numerously as to compel contrast with the severer tastes of later ages. Some of these magatama--curved jewels or perforated cylinders--were made of very hard stone which requires skill to drill, cut and polish. Among the substances used was jade, a mineral found only in Cathay.[3] Indeed, we cannot follow the lines of industry and manufactures, of personal adornment and household decoration, of scientific terms and expressions, of literary, intellectual and religious experiment, without continually finding that the Japanese borrowed from Chinese storehouses. Possibly their debt began at the time of the alleged conquest of Korea[4] in the third century.
