3) Draft speech to be pronounced in front of the citizens of Pesaro, not dated but referable to the year 1900 (“Five years have now passed since I came to Pesaro to direct the Liceo Rossini”). 15 loose sheets numbered and written on the front only, bearing various corrections and afterthoughts.

In 1900 the municipality of Pesaro expressed strong dissatisfaction with the long absences of Mascagni, who had been appointed director of the Rossini musical high school in 1895, due to his innumerable commitments outside the city as an orchestra director. A dispute arose which also involved the ministry (see no. 5 below) and was resolved years later with a positive report on the director's activity. In this speech, addressed to all the citizens of Pesaro, Mascagni forcefully defends his actions at the helm of the Rossini musical high school and lashes out against his detractors: it is certainly not his fault if the theater remained in Pesaro during the five years of his stay in Pesaro mostly always closed and if the public does not show up in large numbers at the concerts of the high school orchestra directed by him.

4) Letter addressed to his wife Lina from Milan in date 21 October 1900 (bifolio on letterhead of the Grand Hotel & de Milan J. Spatz measuring 225x142 mm, preserved in its original envelope), in which Mascagni recounts the extraordinary with great enthusiasm and emotion success had the night before by his Iris: “...it's the first time in Milan you can hear the real Iris; because Toscanini hadn't understood anything about it”. He then recalls: “The Masks give the whole world something to talk about. This execution of Iris will benefit me immediately".

5) Letter addressed to Bonini from Rome dated 18 February 1902 (bifolio measuring 202x131 mm, preserved in his original envelope), in which Mascagni reports to his friend the meeting, in his opinion very positive, that he had with the minister regarding the issue of his absences from the G. Rossini musical high school in Pesaro, of which Mascagni had been director since 1895. In 1900, in fact, the municipality of Pesaro expressed strong dissatisfaction with the latter's long absences due to his innumerable commitments outside the city as conductor. A dispute arose which was resolved with a positive report on the work of the director, who in this letter thanks the Pesaro signatories of the manifesto drawn up in his defence.

6) Letter addressed to Bonini from Florence dated 16 September 1902 (bifolio 180x110 mm, preserved in its original envelope), in which Mascagni refers to an unidentified "affair" that is going for the better , but which is still preferable to keep confidential, and of an unidentified "Maestro", met in Florence, who said he was willing to go to Pesaro to secretly plead Mascagni's cause.

7) Letter addressed to Bonini from Livorno dated 23 September 1902 (bifolio 203x128 mm, preserved in its original envelope), in which Mascagni informs his friend of his next movements (first Florence, then Paris, then finally New York) and provides him with the addresses and contacts where he can be reached in those places. He then adds a note of gossip: “Renganeschi gives me for certain that he ran away with Mrs. Mantovani's lover, while we were together on Saturday night because she came to the station to pick me up. How do you invent certain news?”.

8) Group made up of 5 postcards mostly sent to his friend Bonini from Rome, Bologna, Madrid and Paris; a photographic portrait of Mascagni by the Florentine photographer Giacomo Brogi mounted on cardboard and signed on the reverse “Elisa Villani Sismondo”; a letter envelope from The Powers Hotel in Rochester, N.Y.; an expense report with a drawing of an old man on the front; an envelope containing two business cards, one from Mascagni and one from his wife Lina.
