"My God, are you dumb?"

An expressive look from the Nubian confirmed the insinuation. He put a roll of bank-notes on the package, and made a motion as if he wished to put the latter in his pocket.

"Do you want to buy the whole package?" asked Salvani, breathlessly.

"Yes," nodded the negro.

The impresario looked doubtingly at him, and said:

"But that is eleven boxes on the first tier, each of which costs fifty lire—"

"Yes."

"Twenty-two boxes on the third tier, at thirty-six lire; and all the boxes on the fourth tier, thirty boxes at twenty-five lire."

Again the Nubian nodded. Salvani began to reckon, and excitedly exclaimed:

"But that is impossible. Are you aware that this is a matter of 2,848 lire?"
