And soon they were well afloat in the great stream of London, with the waters roaring and mingling and crying around them. Madeline gazed out, and her wonder deepened as she saw the great shining shops, and the innumerable horses and vehicles, and the people ever coming and going, like waves of a sea. She thought it beautiful, a kind of terrible Fairyland, and it would have given her perfect pleasure if her heart had not been so full of a great grief. For the time being, indeed, she almost forgot her childish trouble in the strange new sense of a vast and troubled world, of whose mysterious motions she had never dreamed. It was a long ride, but it seemed only to occupy a few minutes. Uncle Luke was silent, crushed by his sorrow and by the situation; he held her hand tight, and fixed his poor sad eyes on vacancy, seeing and hearing nothing, only conscious that he had a task to perform, and determined, though his heart should break, that he would perform it to the end. At last they left the long thoroughfares behind and came out into a region comparatively green and countrified, with villas of all tastes and sizes ranged on either side of the road. Here the omnibus stopped, and the conductor told Uncle Luke to alight, announcing that they were at the corner of Willowtree Road, and that the address written on the paper must be close by. So Uncle Luke alighted with Madeline, paid their fare, and stood hesitating, while the omnibus rolled away. Willowtree Road consisted, from end to end, of detached and semi-detached villas, only variegated at two of the corners by public-houses. It was very quiet and suburban, and as all the trees in the gardens were already green, and many of them in flower, it looked quite rural and bright. Paper in hand Uncle Luke trotted up and down for some time, in a vain search for the house he sought. The road was quite deserted, and there was no one whom he could consult. At last he came against a telegraph boy, sauntering along and whistling in the leisurely manner of those swift Mercuries of the period. ‘I’ve just come from there,’ said Mercury, after inspecting the paper. ‘You see that house with the verander? Well, you don’t go up the front steps, but walk round to the side, and you’ll see a bell marked “Stoodio”; ring that, and ask for Mr. White.’ Thus directed, Uncle Luke approached the house, a small, semi-detached villa, and passing round, as directed, to the side, discovered with some little difficulty the bell in question. Without any hesitation, he rang. Scarcely had he done so, when the door opened as it were of its own accord, and he found himself in a dilapidated garden, face to face with a small building which looked like a diminutive Methodist chapel. Approaching the door of this edifice, he was about to knock, when his eyes fell upon a paper pasted upon it. On this paper was printed rather than written these words-- _Mr. White out of town. Back this day week._
