eight o'clock
What are they ? '' `` J. V. M. , '' replied Mrs. Morton . `` Very well . Then at eight o'clock every night I will call J. V. M. slowly a number of times . Then I will tick off the alphabet slowly and the numerals one to ten . You listen in , and if the sounds are blurred or not sharp , tune your instrument as I have shown you until you can hear distinctly . If you make the letters with a pencil as you read them , it may help you .
