'That's a lobster,' cried Montgomery.

'Is it?' cried Kate, and she pursued the ungainly thing, which sought vainly for a crevice.

After an animated chase, with the aid of her parasol she caught it, and was about to take it up with her fingers when Montgomery stopped her.

'You'd better take care; it will pretty well nip the fingers off you.'

'You aren't joking?' she asked innocently.

'No, indeed I'm not; but I hope you don't mind my telling you.'

At that moment their eyes met, and Kate, seeing how foolish she had been, burst into fits of laughter.

'No, no, no, I—I don't mind your telling me that—that a lobster bites, but—'

'But when it comes to saying sea-water is not as nice as brandy-and-soda,' he replied, bursting into a roar of merriment, 'we cut up rough, don't we?'

The children climbed up on the rocks to look at them, and it was some time before Kate could find words to ask them to show what they had caught.
