Nothing came of the idea, but Scavitto’s appearance in court resulted in a comic interlude. Asked on the stand what his business was, he replied that he was in the mosaic business. Asked where his place of business was, he answered: “I ain’t got no business.” From the flat pages of the record it is hard to determine just why his appearance and his explanation caused so much amusement, but according to the _Herald_, when he told of picking up someone else’s hat “the court filled with laughter.” * * * * * It would have been logical for Vanzetti to have followed his alibi witnesses to the stand. However, they had concluded on Friday, July 1, and with the Fourth coming on Monday, Moore did not want to have Vanzetti’s testimony interrupted by the holiday week end. In his place several witnesses were introduced to account for Sacco’s whereabouts on the day of the murders. The first, John Williams, a mild-looking advertising agent, said that he had met Sacco in Boston on April 15 between 1:15 and 1:30 at Boni’s Restaurant in North Square. He had gone into Boni’s for lunch and had seen an acquaintance, Professor Guadagni, sitting at a table with a stranger whom he introduced as Nick Sacco. Guadagni had finished his meal and was smoking a cigar. As the three talked together, Sacco said he planned to go back to Italy and was going to get his passport that afternoon. Williams, who sold advertising space in several foreign-language newspapers, including _La Notizia_, was well known in Boston. It was not so well known that he was a left-wing socialist and had been an associate of Trotsky and Bukharin in New York in 1917. Every Thursday he made the rounds of the small North End factories soliciting help-wanted ads for the Saturday editions. On April 15, according to his advertising book, he had taken an order from the Washington Knitting Mills. Later in the afternoon he had gone uptown to see his doctor, Howard Gibbs, who was treating him for asthma. After the arrest of Sacco and Vanzetti, Felicani asked Williams if he remembered seeing Professor Guadagni and Sacco at Boni’s. Williams said he did. Felicani then asked him if he realized this was the date of the South Braintree crime. Williams had not thought of it, but checking back in his advertising book to the Washington Knitting Mills order, he found it was so. Felicani and Williams felt that this fixed Sacco in Boston instead of in South Braintree. As Williams explained it in court: “The fact that I secured this order and the fact that I met this young man down there, and the fact that he was said to be going for his passport; all of those things brought a sequence of events back to me, and I recalled the incident very easily.”
