Somerset at once perceived that he had been to blame in not thinking of this.
'Please do forgive my thoughtlessness in not reflecting how it would strike you!' he pleaded. 'I--I see I have alarmed you.'
Her alarm was, indeed, much greater than he had at first thought: she trembled so much that she was obliged to sit down, at which he went up to her full of solicitousness.
'You ought not to have done it!' she said. 'I naturally thought--any person would--'
Somerset, perhaps wisely, said nothing at this outburst; the cause of her vexation was, plainly enough, his perception of her discomposure. He stood looking in another direction, till in a few moments she had risen to her feet again, quite calm.
'It would have been dreadful,' she said with faint gaiety, as the colour returned to her face; 'if I had lost my architect, and been obliged to engage Mr. Havill without an alternative.'
'I was really in no danger; but of course I ought to have considered,' he said.
'I forgive you,' she returned good-naturedly. 'I knew there was no GREAT danger to a person exercising ordinary discretion; but artists and thinkers like you are indiscreet for a moment sometimes. I am now going up again. What do you think of the tunnel?'
They were crossing the railway to ascend by the opposite path, Somerset keeping his eye on the interior of the tunnel for safety, when suddenly there arose a noise and shriek from the contrary direction behind the trees. Both knew in a moment what it meant, and each seized the other as they rushed off the permanent way. The ideas of both had been so centred on the tunnel as the source of danger, that the probability of a train from the opposite quarter had been forgotten. It rushed past them, causing Paula's dress, hair, and ribbons to flutter violently, and blowing up the fallen leaves in a shower over their shoulders.
Neither spoke, and they went up several steps, holding each other by the hand, till, becoming conscious of the fact, she withdrew hers; whereupon Somerset stopped and looked earnestly at her; but her eyes were averted towards the tunnel wall.
'What an escape!' he said.
'We were not so very near, I think, were we?' she asked quickly. 'If we were, I think you were--very good to take my hand.'
They reached the top at last, and the new level and open air seemed to give her a new mind. 'I don't see the carriage anywhere,' she said, in the common tones of civilization.
