"I had grown so interested that I had leaned far across the table. Daisy, too, bent forward. It was only when the professor paused for a moment that I noticed how close together our heads were--Daisy's and mine. I don't think she realized it. She did not move. "'Now comes the important part of this long discourse,' said the professor, smiling at our eagerness. "'Ever since the carcass of our derelict thermosaurus was first noticed, every captain who has seen it has also reported the presence of one or more gigantic birds in the neighborhood. These birds, at a great distance, appeared to be hovering over the carcass, but on the approach of a vessel they disappeared. Even in mid-ocean they were observed. When I heard about it I was puzzled. A month later I was satisfied that neither the ekaf-bird nor the ool-yllik was extinct. Last Monday I knew that I was right. I found forty-eight distinct impressions of the huge, seven-toed claw of the ekaf-bird on the beach here at Pine Inlet. You may imagine my excitement. I succeeded in digging up enough wet sand around one of these impressions to preserve its form. I managed to get it into a soap-box, and now it is there in my shop. The tide rose too rapidly for me to save the other footprints.' "I shuddered at the possibility of a clumsy misstep on my part obliterating the impression of an ool-yllik. "'That is the reason that my daughter warned you off the beach,' he said, mildly. "'Hanging would have been too good for the vandal who destroyed such priceless prizes,' I cried out, in self-reproach. "Daisy Holroyd turned a flushed face to mine and impulsively laid her hand on my sleeve. "'How could you know?' she said. "'It's all right now,' said her father, emphasizing each word with a gentle tap of his pipe-bowl on the table-edge; 'don't be hard on yourself, Dick. You'll do yeoman's service yet.' "It was nearly midnight, and still we chatted on about the thermosaurus, the ekaf-bird, and the ool-yllik, eagerly discussing the probability of the great reptile's carcass being in the vicinity. That alone seemed to explain the presence of these prehistoric birds at Pine Inlet. "'Do they ever attack human beings?' I asked. "The professor looked startled. "'Gracious!' he exclaimed, 'I never thought of that. And Daisy running about out-of-doors! Dear me! It takes a scientist to be an unnatural parent!' "His alarm was half real, half assumed; but, all the same, he glanced gravely at us both, shaking his handsome head, absorbed in thought. Daisy herself looked a little doubtful. As for me, my sensations were distinctly queer. "'It is true,' said the professor, frowning at the wall, 'that human remains have been found associated with the bones of the ekaf-bird--I don't know how intimately. It is a matter to be taken into most serious consideration.' "'The problem can be solved,' said I, 'in several ways. One is, to keep Miss Holroyd in the house--' "'I shall not stay in,' cried Daisy, indignantly.
