It is widely known that there are “two-line” (lianghang 兩行) slips among bamboo and wooden slips from the Han period. Among these “two-line” slips dating from the second half of the Former Han and unearthed in the Hexi 河西 region, there exist two types: one type has a ridge down the centre of the writing surface which divides the two lines, while the other type has a flat surface with no ridge. However, in the past there has been no examination of this difference. In this article, I focus primarily on the “two-line” slips among the Dunhuang 敦煌 Han slips, unearthed in former Dunhuang Commandery in Hexi, and compare them with the “two-line” slips among the Juyan 居延 Han slips unearthed in former Zhangye 張掖 Commandery, also in Hexi. By this means, I clarify the fact that there exist various differences, starting with the shape of slips of the same type, between regions and government offices, and I also gain leads for adding further depth to research so that it extends to regional differences between slips. There was found a clear-cut difference between the Dunhuang Han slips, which include roughly the same number of “two-line” slips with a ridge and without a ridge, and the Juyan Han slips, which include almost no “two-line” slips with a ridge. In the case of the Xuanquan 懸泉 Han slips from Dunhuang, wood from the tamarisk (hongliu 紅柳; Tamarix ramosissima) is used in more than 70% of the “two-line” slips with ridges, and few of them have been made from spruce (song 松; Picea neoveitchii or Picea crassifolia), used in many of the “two-line” slips without a ridge. In addition, the “two-line” slips with ridges are narrower than those without a ridge. In view of these facts, it is to be surmised that in order to make effective use of the branches of the tamarisk, which, properly speaking, are unsuitable for making “two-line” slips because they are comparatively narrow, and produce “two-line” slips, the branches were processed in the same way as “two-line” bamboo slips so as to add ridges to them. It was for this reason that regional differences in shape arose among slips of the same type. When one examines the reasons for these differences, it is to be surmised that differences in regional conditions lay behind them. That is to say, the Juyan region belonged to Zhangye Commandery, where a transportation route had been established to the Qilian 祁連 Mountains where spruce suitable for making wide “two-line” slips were produced, whereas Dunhuang Commandery did not have a large supply of spruce because it was a long way from the Qilian Mountains and use could not be made of transportation by water or some other means.
