"Thank you, sir; thank you!" Tom cried fervently. "I have something to live for now. This separation will but make our hearts grow fonder. What change can time make in either of us?" "Quite so," said John Girdlestone, with a smile. "Remember there must be no more walking through the square. You must remain absolutely apart if you wish to gain my consent." "It is hard, very, very hard. But I will promise to do it. What would I not promise which would lead to our earlier union?" "That is settled then. In the mean time, I should be obliged if you would go down to the docks and look after the loading of the transferable corrugated iron houses for New Calabar." "All right, sir, and thank you for your kindness," said Tom, bowing himself out. He hardly knew whether to be pleased or grieved over the result of his interview; but, on the whole, satisfaction prevailed, since at the worst it was but to wait for a year or so, while there seemed to be some hopes of gaining the guardian's consent before that. On the other hand, he had pledged himself to separate from Kate; but that would, he reflected, only make their re-union the sweeter. All the morning he was engaged in superintending the stowing of great slabs of iron in the capacious hold of the _Maid of Athens_. When the hour of luncheon arrived no thought of food was in the lad's head, but, burying himself in the back parlour of a little Blackwall public-house, he called for pen, ink, and paper, and proceeded to indite a letter to his sweetheart. Never was so much love and comfort and advice and hope compressed into the limits of four sheets of paper or contained in the narrow boundary of a single envelope. Tom read it over after he had finished, and felt that it feebly expressed his thoughts; but, then, what lover ever yet did succeed in getting his thoughts satisfactorily represented upon paper. Having posted this effusion, in which he had carefully explained the conditions imposed upon him, Tom felt considerably more light-hearted, and returned with renewed vigour to the loading of the corrugated iron. He would hardly have felt so satisfied had he seen John Girdlestone receiving that same letter from the hands of the footman, and reading it afterwards in the privacy of his bedroom with a sardonic smile upon his face. Still less contented would he have been had he beheld the merchant tearing it into small fragments and making a bonfire of it in his capacious grate. Next morning Kate looked in vain out of the accustomed window, and was sore at heart when no tall figure appeared in sight and no friendly hand waved a morning salutation. CHAPTER XXV. A CHANGE OF FRONT. This episode had occurred about a fortnight before Ezra's return from Africa, and was duly retailed to him by his father.
