`` The old man pulls out a memorandum book and hunts in it . ` The 25th of April , Deering , ' says he . ` I know it , ' says Sir Percival . ` And ten minutes to twelve o'clock , ' says the old man . ` By Jupiter ! you have n't won yet . ' And he pounds the table with his fist and yells to me : ` Waiter , call the manager at once -- tell him to hurry here as fast as he can . '
