"Do you know this Paul Zobriskie?" he asked, earnestly.

"No. I never met him until I saw him on the steamer, and he asked me to deliver this letter to you," said he.

"Are you sure of that?"

"I am."

"And know nothing about him?"

"Nothing further than hearing of him as a socialistic agitator."

"And you know nothing of the contents of this letter?"

"Nothing whatever. He told me nothing further than that it was important, and that I must give it to no one but you."
