By _Method and discipline_ are to be understood the marshalling of the
army in its proper subdivisions, the gradations of rank among the
officers, the maintenance of roads by which supplies may reach the
army, and the control of military expenditure.
The Chinese of this sentence is so concise as to be practically
unintelligible without commentary. I have followed the
interpretation of Ts‘ao Kung, who joins 曲制 and again 主用. Others
take each of the six predicates separately. 曲 has the somewhat
uncommon sense of “cohort” or division of an army. Capt. Calthrop
translates: “Partition and ordering of troops,” which only covers
曲制.
