| 文本 | 361 DR. SEWARD'S DIARY Professor. He had evidently expected some such call, for I found him dressed in his room. His door was ajar, so that he could hear the opening of the door of our room. He came at once, as he passed into the room, he asked Mina if the others might come, too. "No," she said quite simply, "it will not be necessary. You can tell them just as well. I must go with you on your journey." Dr. Van Helsing was as startled as I was. After a mo- ment's pause he asked :- "But why?" "You must take me with you.

You are strong in your numbers, for you can defy that which would break down the human endurance of one who had to guard alone. Be- sides, I may be of service, since you can hypotise me and so learn that which even I myself do not know." Dr. Van Helsing said very gravely "Madam Mina, you are, as always, most wise. You shall with us come; and together we shall do that which we go forth to achieve." When he had spoken, Mina's long spell of silence made me look at her. She had fallen back on her |
