William cleared his throat with a certain dignity and made no answer.
“Tell him, Henry.”
Henry ceased his enthralling occupation of trying to push a fly into his ink-well with his nib and answered mechanically:
“Two negatives make an affirmative.”
“Yes. Say that, William.”
William repeated it without betraying any great interest in the fact.
“Yes. What’s a negative, William?”
William sighed.
“Somethin’ about photographs?” he said obligingly.
