n. An agency employed by civilized nations for the settlement of disputes which might become troublesome if left unadjusted. By most writers the invention of gunpowder is ascribed to the Chinese but not upon very convincing evidence. Milton says it was invented by the devil to dispel angels with and this opinion seems to derive some support from the scarcity of angels. Moreover it has the hearty concurrence of the Hon. James Wilson Secretary of Agriculture.
