stations with their evening entertainments on 360 meter waves and heard only the meaningless or uninteresting Morse messages passing from ships to shore or vice versa.
Over and over Tom and Frank glanced anxiously at the little nickel-plated clock ticking merrily on its shelf, until at last the hands pointed to 7:45 and the boys fairly thrilled with excitement. Would they hear the message from the speeding ship? Would they pick up that one message that they were expecting? Would they, in a moment more, be listening to the dots and dashes that represented Mr. Pauling’s words? Neither boy was yet expert at reading Morse if sent rapidly, but the wireless man aboard the Havana had laughingly agreed to send Mr. Pauling’s messages slowly and the boys were not worried on that score.
Suddenly, to Tom’s ears, came a sharp buzz—faint and blurred, and with trembling fingers he tuned his set, adjusted the variable condenser and as the short, staccato sounds grew sharp, loud and clear he knew that the long-hoped-for message was coming to his ears. “Dah, dah dah dah, dah dah, dee dah dah dee, dee dah, dee dee dah, dee dah
dee dee, dee dee, dah dee, dah dah dee,” came the dots and dashes, sent slowly as if by an amateur and mentally Tom translated them. Yes, there was no doubt of it, TOM PAULING were the words the dots and dashes spelled and Tom’s heart beat a trifle faster and his face flushed with excitement as he heard his own name coming out of space and realized that, across a hundred miles and more of tossing sea, his father was talking to him and steadily he jotted down the letters as they buzzed in dots and dashes through the air from the distant ship.
“Hurrah!” he fairly yelled, as with the final “dee dah dee dah dee” the operator signified that the message was finished. “Hurrah! I got it. See, here ’tis, Mother!”
Frank also had received the message on his set and the two compared the letters they had written down.
“Of course we made some mistakes,” explained Tom as his mother puzzled over the unpunctuated, apparently meaningless letters. “See,” he continued, “you have to separate the letters into words and sentences and this one should be an “N” instead
of an “A” and I guess this is a “D” instead of a “B,” Frank’s got it that way. One’s a dash and three dots and the other’s a dash and two dots.”
As he spoke, Tom was busily copying the letters and forming words and presently showed his mother the finished message. “That’s it,” he announced proudly. “Just think of Dad talking to us—and he’ll do it every night all the way down and after he gets there. Gosh! It’s funny to think we can hear from him that way. Say, isn’t radio great?”
“But I thought you could hear him talking,” said his mother in rather disappointed tones. “He could send messages that way by the regular radio companies or by cable.”
