'Parker's Spinney, I expect,' put in Merevale.

'Yes, sir. About a mile from the College.'

'And you saw nothing more of him after that?' inquired the Headmaster.

'No, sir. He was lying on his back when I left him. I should think some of the others must have seen him after I did. He didn't look as if he was likely to get up for some time.'

'Well,' said the Head, as he and Merevale went out of the room, leaving Welch to his slumbers, 'we have gained little by seeing Welch. I had hoped for something more. I must send the prefects out to look for Thomson at once.'

'It will be a difficult business,' said Merevale, refraining—to his credit be it said—from a mention of needles and haystacks. 'We have nothing to go upon. He may be anywhere for all we know. I suppose it is hardly likely that he is still where Welch left him?'

The Head seemed to think this improbable. 'That would scarcely be the case unless he were very much exhausted. It is more than five hours since Welch saw him. I can hardly believe that the worst exhaustion would last so long. However, if you would kindly tell your House-prefects of this—'

'And send them out to search?'

'Yes. We must do all we can. Tell them to begin searching where Thomson was last seen. I will go round to the other Houses. Dear me, this is exceedingly annoying. Exceedingly so.'

Merevale admitted that it was, and, having seen his visitor out of the House, went to the studies to speak to his prefects. He found Charteris and Tony together in the former's sanctum.
