Arthur's own family were more thoughtful and intelligent people. "I knew," said Grandfather, "that the marvels of electricity were not all understood. When I was a young man, the telegraph was the greatest wonder the world owned. But using that was somehow like talking at arm's length; the telephone brings your friend almost beside you." "To me," said Arthur's mother, "the telephone, in comparison with the telegraph, seems like a highly finished oil painting. The old invention is like a page of black and white print." "Why, I have seen Mr. Bell," remembered Arthur's older sister, who was studying to be a teacher, after she had heard the story. "He came to the normal school last year to explain his system of teaching deaf mutes to speak." The Burtons heard no more of the telephone for six months or more; but the next winter, when Herbert, the older brother, came home from Tufts College to spend a week end, he exclaimed: "Well, Arthur, I've talked through a telephone, too!" "You have!" "Where?" "Tell us about it!" were the quick replies. "Professor Dolbear, the physics instructor, has made one in his laboratory. It's a little different from Professor Bell's. Your professor, Arthur, had a battery, you know, to make the electro-magnet. My professor has a permanent magnet instead." Early in February Herbert came home with more news and an invitation: "Professor Bell is going to give a public lecture and exhibition of his telephone at Salem next Monday evening. He expects to carry on a conversation with people in Boston. Want to go back to college with me Monday morning, Arthur, and go down to Salem in the evening?" So it happened that on Monday evening, February 12, 1877, Arthur and Herbert, with about five hundred others, were at Lyceum Hall in Salem. It was an eager audience, full of curiosity. Upon the platform and well toward the front was a small table, on the top of which rested an unimportant-looking covered box. From this box wires extended above to the gas fixture and out through the hall. At the back of the platform was a blackboard on a frame, and at the side a young woman, an expert telegrapher, who was to help Mr. Bell. "Rather an unpromising set of apparatus!" Arthur heard a man behind him whisper to his neighbor. "I'm not expecting much," returned the neighbor. "They say Professor Bell's going to talk to Boston. That's nonsense!" But just then Professor Bell began. He briefly explained the instrument upon the table, which, Arthur saw, varied but little from that at Philadelphia. "Only," thought Arthur, "he uses it now as he said he should, for transmitting and receiving too." Then Professor Bell gave a brief account of the studies he had made since 1872, when he came to Boston to teach speech to deaf mutes.
