When from one's own country or from another's country merchandise or commodities for manufacture in a manufactory are going to an enemy's country, spies may spread the information that those commodities are obtained from one whom the enemy wanted to march against. When commodities are thus gathered in abundance (the owner of the articles) may send a message to the enemy: "These commodities and merchandise are sent by me to you; please declare war against the combined kings or desert them; you will then get the rest of the tribute." Then spies may inform the other kings of the combination; "These articles are given to him by your enemy."
