Among the perquisites of the Camorrists was the monopoly of gambling. A tax was levied upon every game of _morra_ played,--a favourite amusement with all Neapolitans. It is simplicity itself; one player holds up his doubled fist and throws out one or more fingers and the other guesses the number as they are displayed. If one cries “five” and the number of fingers is three or four, the other player wins. In the prisons the stakes were measures of wine, also supplied by the Camorra, which in this way made money all round. The gains were very substantial when affairs prospered, and as much as £40 or £50 was paid into the society’s treasury every week. The organisation was extensive and all the prisons were brought into it. How well the system worked was to be seen in a correspondence between the chief Camorrist and one of his subordinate lieutenants in another prison which was shown to Mr. Marc Monnier. These letters, by many different hands, proving that the chief was no scholar and had to depend upon the literary skill of others, dealt largely with the affairs of the society, which issued orders, gave decisions, inflicted punishments, and divided its funds. All the current news was passed on, prison arrivals and departures, new sentences and terms expired. The most remarkable thing was the facility and regularity with which these clandestine letters were passed in and out of the prisons; no doubt the wardens were always at the service of the Camorrists and helped them in every way.
