And lifting them carefully one off the other, he took out a deal box that had stood in the lowest stratum. The cover was loose, except for a string tied about it. He laid it upon the floor, and took out a plaster mask, and brushing and blowing off the saw-dust, held it up.

David Arden saw a face with large eyes closed, a very high and thin nose, a good forehead, a delicately chiselled mouth; the upper lip, though well formed after the Greek model, projected a little, and gave to the chin the effect of receding in proportion. This slight defect showed itself in profile; but the face, looked at full front, was on the whole handsome, and in some degree even interesting.

“You are quite sure of the identity of this?” asked Uncle David earnestly.

There was a square bit of parchment, with two or three short lines, in a character which he did not know, glued to the concave reverse of the mask. The baron took it, and holding the light near, read, “Yelland Mace, suspect for his politics, May 2nd, 1844.”

“Yes,” said Mr. Arden, having renewed his examination, “it very exactly tallies with the description; the nose aquiline, but very delicately formed. Is that writing in cypher?”

“Yes, in cypher.”

“And in what language?”

“German.”
