“A treasury note is presented of the value of fifty dollars; the cue is:
“‘Look at this. Be quick.’
“Answer. ‘A treasury note.’
“‘Will you tell me the amount? Come;’ which means 5 and 0, or $50; ‘come’ being a substitute for ‘hurry.’
“Again, a $2.50 gold piece is presented, and the question is as before:
“‘Look at this. Will you?’
“Answer. ‘A gold piece.’
“‘Let me know the amount. Won’t you? Come.’ ‘Let,’ ‘won’t,’ and ‘come’ standing for ‘250.’
