CHAPTER IX.
With an oath Giovanni raised his hand to strike Zorzi in the face, but the quick Dalmatian snatched up his heavy blow-pipe in both hands and stood in an attitude of defence.
"If you try to strike me, I shall defend myself," he said quietly.
Giovanni's sour face turned grey with fright, and then as his impotent anger rose, the grey took an almost greenish hue that was bad to see.

He smiled in a sickly fashion.

Zorzi set the blow-pipe upright against the furnace and watched him, for he saw that the man was afraid of him and might act treacherously.
"You need not be so violent," said Giovanni, and his voice trembled a little, as he recovered himself.

"After all, my father would not have made any objection to my trying the glass.

If I had, I could not have guessed how it was made." Zorzi did not answer, for he had discovered that silence was his best weapon.
