"You had better take my arm," he said, as she hastily disengaged herself before it was safe to do so, and was immediately caught in the eddy that was setting strongly in the direction of the Exhibition. "If you don't mind waiting here for a few minutes longer, you will be able to get home comfortably." She struggled back to his side, and took his arm, and waited; but they did not talk any more. They watched the disintegration and dispersion of the great mass that had hemmed them in together, until at last they stood in ease and freedom almost alone upon that coign of vantage which had been won with so much difficulty--two rather imposing figures, if anyone had cared to notice them. Then she withdrew her hand, and said, with a little stiff bow and a bright and becoming colour in her face--"_Thank_ you." "Don't mention it," he replied, with perfect gravity. "I am very happy to have been of any service to you." Still they did not move from where they stood. "Don't you want to see the rest of it?" she asked timidly. "Do you?" he responded, looking at her with a smile. "O dear no, thank you! I have had quite enough, and I am very anxious to find my sisters." "Then allow me to be your escort until you are clear of the streets." He did not put it as a request, and he began to descend the steps before she could make up her mind how to answer him. So she found herself walking beside him along the footpath and through the Gardens, wondering who he was, and how she could politely dismiss him--or how soon he would dismiss her. Now and then she snatched a sidelong glance at him, and noted his great stature and the easy dignity with which he carried himself, and transferred one by one the striking features of his countenance to her faithful memory. He made a powerful impression upon her. Thinking of him, she had almost forgotten how anxious she was to find her sisters until, with a start, she suddenly caught sight of them sitting comfortably on a bench in an alley of the Fitzroy Gardens, Eleanor and Patty side by side, and Paul Brion on the other side of Eleanor. The three sprang up as soon as they saw her coming, with gestures of eager welcome. "Ah!" said Elizabeth, her face flaming with an entirely unnecessary blush, "there are my sisters. I--I am all right now. I need not trouble you any further. Thank you very much." She paused, and so did he. She bent her head without lifting her eyes, and he took off his hat to her with profound respect. And so they parted--for a little while. CHAPTER XVII. AFTERNOON TEA. When he had turned and left her, Elizabeth faced her sisters with that vivid blush still on her cheeks, and a general appearance of embarrassment that was too novel to escape notice. Patty and Eleanor stared for a moment, and Eleanor laughed. "Who is he?" she inquired saucily. "I don't know," said Elizabeth. "Where have you been, dears? How have you got on? I have been so anxious about you." "But who is he?" persisted Eleanor.
