Measure makers (lishi b氏), plough makers (duanshi 段氏) (lost)

Measure makers called (lishi ¹ ) make measures of capacity (liang ² ). They purify the samples of metal (copper) and tin by successively heating them, until there is no further loss of weight. Then they weigh them (quanzhi ³ ). After weighing, they rectify and adjust the mold (zhunzhi ⁴ ), and after that they cast and examine the capacity of the measure (liangzhi ⁵ ). They cast the standard measure of capacity fu ⁶ in this way. The fu is of one chi in depth, having a circular base whose inscribed square has a side of one chi, ⁷ and it holds one fu; its base is one cun deep, and it holds one dou ⁸ ; two handles are three cun deep, and each holds one sheng ⁹ . The measure fu weighs one jun. ¹⁰ The standard ruler of the measure of capacity is consistent with that of the pitch pipe which sounds like the tone gong ¹¹ in the pitch of the Huangzhong. ¹² The people use it as a pattern by which to make or check others, and no duty is levied thereon. ¹³
