with the Brotherhood by a secret mark, which we all bear, which lasts while our lives last.  We are told to go about our ordinary business, and to report ourselves to the president, or the secretary, four times a year, in the event of our services being required.  We are warned, if we betray the Brotherhood, or if we injure it by serving other interests, that we die by the principles of the Brotherhood—­die by the hand of a stranger who may be sent from the other end of the world to strike the blow—­or by the hand of our own bosom-friend, who may have been a member unknown to us through all the years of our intimacy.  Sometimes the death is delayed—­sometimes it follows close on the treachery.  It is our first business to know how to wait—­our second business to know how to obey when the word is spoken.  Some of us may wait our lives through, and may not be wanted.  Some of us may be called to the work, or to the preparation for the work, the very day of our admission.  I myself—­the little, easy, cheerful man you know, who, of his own accord, would hardly lift up his handkerchief to strike down the fly that buzzes about his face—­I, in my younger time, under provocation so dreadful that I will not tell you of it, entered the Brotherhood by an impulse, as I might have killed myself by an impulse.  I must remain in it now—­it has got me, whatever I may think of it in my better circumstances and my cooler manhood, to my dying day.  While I was still in Italy I was chosen secretary, and all the members of that time, who were brought face to face with my president, were brought face to face also with me.”

I began to understand him—­I saw the end towards which his extraordinary disclosure was now tending.  He waited a moment, watching me earnestly—­watching till he had evidently guessed what was passing in my mind before he resumed.

“You have drawn your own conclusion already,” he said.  “I see it in your face.  Tell me nothing—­keep me out of the secret of your thoughts.  Let me make my one last sacrifice of myself, for your sake, and then have done with this subject, never to return to it again.”

He signed to me not to answer him—­rose—­removed his coat—­and rolled up the shirt-sleeve on his left arm.

“I promised you that this confidence should be complete,” he whispered, speaking close at my ear, with his eyes looking watchfully at the door.  “Whatever comes of it you shall not reproach me with having hidden anything from you which it was necessary to your interests to know.  I have said that the Brotherhood identifies its members by a mark that lasts for life.  See the place, and the mark on it for yourself.”

He raised his bare arm, and showed me, high on the upper part of it and in the inner side, a brand deeply burnt in the flesh and stained of a bright blood-red colour.  I abstain from describing the device which the brand represented.  It will be sufficient to say that it was circular in form, and so small that it would have been completely covered by a shilling coin.
