At five o’clock in the morning, the sergeant again summons his men; on this occasion, to open the gates of the Tower. The ceremony, though essentially similar to the midnight one, is perhaps a little more hurriedly performed in the unlocking than it is in the locking of the gates; and the officer on guard does not appear in the morning, though we may safely assume that he had to ‘turn out’ when the opening of the Tower was a more significant matter than it happily now is. But besides being present with his guard at midnight, he has other duties to carry out: by day, he marches off the ‘relief’ at intervals of two hours; and in the afternoon goes round the sentries, hearing them repeat their orders—an almost obsolete custom, but still kept up in the Tower. Previous to the hour appointed for this ordeal, the men may be seen studiously reading their instructions, or committing them to memory as they pace up and down. By night, the officer goes his ‘rounds’ accompanied by a small escort, including the drummer-boy and his rather opaque lantern. In the course of this tour, every sentinel connected with the garrison is visited; and by the time the rounds return to the Main Guard, the members of that important body have usually been called into activity by the loud cry of ‘Keys!’ IN ALL SHADES. CHAPTER XIV. Edward and Marian spent their first week in Trinidad with the Hawthorns senior. Mrs Hawthorn was kindness itself to Marian—a dear, gentle, motherly old lady, very proud of her boy, especially of his ability to read Arabic, which seemed to her a profundity of learning never yet dreamt of in the annals of humanity—and immensely pleased with her new daughter-in-law; but nothing on earth that Marian could say to her would induce her to unlock the mystery of that alarming telegram. ‘No, no, my dear,’ she would say, shaking her head gloomily and wiping her spectacles, whenever Marian recurred to the subject, ‘you’ll find it all out only too soon. God forbid, my darling, that ever I should break it to you. I love you far too well for that. Marian, Marian, my dear daughter, you should never, never, never have come here!’ And then she would burst immediately into tears. And that was all that poor frightened Marian could ever get out of her new mother-in-law.
