《墨子·71章 杂守》
如敌兵逼近，就加紧收集偏远地区的金器，铜铁及其它可以用来帮助守城用的物品，先调查登记县中官吏、官府中不急需用的物品、木材大小、长短及总数，赶紧先发送进城。
寇近，亟收诸杂乡金器若铜铁及他可以左守事者。先举县官室居、官府不急者，材之大小长短及凡数，即急先发。
If the enemy troops are approaching, then the gold, copper, iron, and other items that can help defend the city from the outlying areas should be quickly collected and the county officials’ personal possessions, unnecessary items in the government offices, the quantities, lengths, and diameters of the lumber should be investigated and registered, and quickly sent into the city.
