'I really beg your pardon, Miss Fortescue,' Captain Armstrong said, penitently, 'but there are certain provocations under which even the mildest of men may be excused for breaking down.'

'I do not see where the provocation comes in,' she said; 'we were merely discussing the conduct of engaged couples in general, and of Lord Halliburn in particular.'

'I would rather not discuss the matter at all. I have nothing whatever to say against him; he may be an excellent fellow for anything I know, but at the present moment it is distinctly unfortunate that he has turned up here, and I hope he will have the common sense to see it himself, and to start the first thing in the morning.'

But this Lord Halliburn did not do; he and his two friends started early for the Mer de Glace, while the Hawtreys' party went off on mules in another direction. After dinner the men met in the balcony and smoked their cigars together, the only absentee being Captain Armstrong, who went for a walk by himself. On the following day the Hawtreys determined to visit the Mer de Glace. Mr. Singleton and Mrs. Fortescue declined to form part of the expedition; the others took two guides with them, as the ice was said to be in bad condition. They started at six in the morning, and made a considerable portion of the ascent on mules. When they reached the edge of the glacier, the guides, who had been consulting together as they led the way, said that they should not advise them going far, for the weather looked bad. Mont Blanc was wreathed in clouds, and the other peaks were also hidden.

'What do you expect, Giuseppe?' Mr. Hawtrey asked. 'There is no wind, and the clouds do not look any lower than they did an hour ago.'

'The storms here are very sudden,' the guide replied, 'and when they do sweep down they come with terrible violence, and Conrad and I both think there may be snow. With these ladies it would not be safe to venture far on the ice.'

'Well, we will only go as far as you think it safe. It would be a pity to have had this climb for nothing.'

'All must keep together,' the guide said; 'let there be no straying. The snow, over some of the crevasses, is very thin and treacherous.'

On they went for some distance, admiring the ice pinnacles, leaning over crevasses, and peering down into the depths where the deep blue of the ice walls shaded off into blackness. The guides went ahead, sounding carefully the snow before them for a few inches, the first precursor of coming change, had fallen two days before. Suddenly one of the guides uttered an exclamation.

'See,' he said, 'the clouds are coming down the mountains. We have not a moment to lose; it will be on us now before we are off the glacier.'
