 that devised by Morse, but as Vail grew more intimate with the subject his own ingenuity came into play, and he soon improved on the original. The pencil was discarded for a fountain pen, and the zig-zag signals for the short and long lines now termed 'dots' and 'dashes.'

This important alteration led him to the 'Morse alphabet,' or code of signals, by which a letter is transmitted as a group of short and long jets, indicated as 'dots' and 'dashes' on the paper. Thus the letter e, which is so common in English words, is now transmitted by a short jet which makes a dot; t, another common letter, by a long jet, making a dash; and q, a rare letter, by the group dash, dash, dot, dash. Vail tried to compute the relative frequency of all the letters in order to arrange his alphabet; but a happy idea enabled him to save his time. He went to the office of the local newspaper, and found the result he wanted in the type-cases of the compositors. The Morse, or rather Vail code, is at present the universal telegraphic code of symbols, and its use is extending to other modes of signalling-for example, by flags, lights, or trumpets.

The hard-fisted farmers of New Jersey, like many more at that date, had no faith in the 'telegraph machine,' and openly declared that the judge had been a fool for once to put his money in it. The judge, on his part, wearied with the delay, and irritated by the sarcasm of his neighbours, grew dispirited and moody. Alfred, and Morse, who had come to assist, were careful to avoid meeting him. At length, on January 6, 1838, Alfred told the apprentice to go up to the house and invite his father to come down to see the telegraph at work. It was a cold day, but the boy was so eager that he ran off without putting on his coat. In the sitting-room he found the judge
