Generals with only one or two ships raise less; those with a larger fleet raise more. Also those who pay do not pay the sum, be it large or small, for nothing; they are not such madmen. No, they purchase for the merchants sailing from their own harbors immunity from injury or robbery, or a safe conduct for their own ships, or something of that sort. They say that they are granting benevolences. That is the name for these exactions.
