In October 1780, his appointment was more definitely established and he was given a salary of fifteen ducats a month.  This, with the six sequins of life-income left by Barbaro and the six given by Dandolo, gave him a monthly income of three hundred and eighty-four lires—­about seventy-four U. S. dollars—­from 1780 until his break with the Tribunal at the end of 1781.

In the Archives of Venice are preserved forty-eight letters from Casanova, including the Reports he wrote as a “Confidant,” all in the same handwriting as the manuscript of the Memoirs.  The Reports may be divided into two classes:  those referring to commercial or industrial matters, and those referring to the public morals.

Among those of the first class, we find: 

A Report relating to Casanova’s success in having a change made in the route of the weekly diligence running from Trieste to Mestre, for which service, rendered during Casanova’s residence at Trieste in 1773, he received encouragement and the sum of one hundred ducats from the Tribunal.

A Report, the 8th September 1776, with information concerning the rumored project of the future Emperor of Austria to invade Dalmatia after the death of Maria Theresa.  Casanova stated he had received this information from a Frenchman, M. Salz de Chalabre, whom he had known in Paris twenty years before.  This M. Chalabre [printed Calabre] was the pretended nephew of Mme. Amelin.  “This young man was as like her as two drops of water, but she did not find that a sufficient reason for avowing herself his mother.”  The boy was, in fact, the son of Mme. Amelin and of M. de Chalabre, who had lived together for a long time.

A Report, the 12th of December 1776, of a secret mission to Trieste, in regard to a project of the court of Vienna for making Fiume a French port; the object being to facilitate communications between this port and the interior of Hungary.  For this inquiry, Casanova received sixteen hundred lires, his expenditures amounting to seven hundred and sixty-six lires.

A Report, May-July 1779, of an excursion in the market of Ancona for information concerning the commercial relations of the Pontifical States with the Republic of Venice.  At Forli, in the course of this excursion, Casanova visited the dancing-girl Binetti.  For this mission Casanova received forty-eight sequins.

A Report, January 1780, remarking a clandestine recruiting carried out by a certain Marrazzani for the [Prussian] regiment of Zarembal.

A Report, the 11th October 1781, regarding a so-called Baldassare Rossetti, a Venetian subject living at Trieste, whose activities and projects were of a nature to prejudice the commerce and industry of the Republic.

Among the Reports relating to public morals may be noted: 

December 1776.  A Report on the seditious character of a ballet called “Coriolanus.”  The back of this report is inscribed:  “The impressario of S. Benedetto, Mickel de l’Agata, shall be summoned immediately; it has been ordered that he cease, under penalty of his life, from giving the ballet Coriolanus at the theater.  Further, he is to collect and deposit all the printed programmes of this ballet.”
