When Jack and Alice Denfield's mother heard the story of this adventure of theirs, she was much annoyed at first, and thought they must have been in a good deal of danger. Afterward, when she was convinced that they came to no harm but very slight colds, she laughed at them heartily, and said it had been a good lesson, and if she had been twenty years younger she probably should have enjoyed it as much as they did.

They had all three been staying at the White Mountains; they had planned to be at the Glen House through July and early August, and then go to the sea-shore to stay until late in September. But the very first of August Mrs. Denfield found that she must go to Boston for a few days to attend to some business; and they were all sorry, for they had counted upon having a week or ten days more among the mountains. They had had a most satisfactory time, for they knew a charming set of people at the hotel, and every pleasant day there had been long drives or walks, small fishing parties or large picnics. Jack and Alice always were glad to be together; they were very near the same age, and had always been great cronies from their babyhood. They were equally fond of out-of-door life; Jack had said more than once that his sister was exactly as good company as another fellow, and she responded that she did not have such good times with anybody else in the world. I think it is seldom one sees such a friendship between a brother and sister. They both had a great many friends, but they were always delighted to have vacation come, and get back to each other.

They came in late to supper one Monday evening. They had been out all day, and it was their last chance for a long expedition, for they were to go down by the stage the next day to take the train. For a little while Jack was uncommonly silent, and did not pay much attention to the chattering of the other young people at the table; but suddenly he said to Alice, who happened to sit next him, "I have made a plan"; and she stopped to listen to it with great interest. "Suppose we ask mamma to let us stay here a little longer, and then go down to Boston by ourselves? She will have to be there for a week, she told me, and we could go up Mount Washington with the Eastfields and Dunns. You know they're going to walk up the mountain, and stay all night. It'll be great fun."

Alice was delighted at the idea, and after supper was over they went at once to propose this change of plans.

"I do not know why not," said Mrs. Denfield, slowly. "You are surely familiar enough with travelling, and almost grown up, at any rate, you tall creatures! But you must not take any longer journey" (they had all three wished to go farther up among the mountains); "you must be in Boston Saturday evening."

So next day Mrs. Denfield started off by herself, and Alice said, just after the stage had gone, "I wish we had asked mamma if we could not walk part of the way; we could send our trunks on by the stage to North Conway."

Jack's eyes began to shine with delight. "Of course she wouldn't mind," said the boy. "Don't you remember how sorry she was when you couldn't go down through the Notch with the rest of us last summer, because you had sprained your ankle? Let's do it, Alice. We can go up Mount Washington to-morrow, and come down next day. Yes, there will be just time enough to reach Boston Saturday night. Why, it's nothing to do; we have walked almost as far a dozen times."

"But not by ourselves," said Alice, "in such a wild country. I'm not a bit afraid, though—you needn't think that."

So they made their plans, and kept them great secrets, for Jack said that everybody would insist upon going with them, and making a public occasion of it, and it would be much better fun to go alone by themselves. They had often taken short excursions together, and they knew that they could get on much faster. It was settled that they were to start early Friday morning, and to say good-by to everybody the evening before, and then go away even before any one would be down to see them start by the stage.

The walking party up Mount Washington was a grand success, and the afternoon and evening of the day were just the right sort of weather, cool and fresh and bright, with a most glorious sunset, and a clear though very late moonrise. But next morning it was damp and cloudy, and most of the party thought it would be more sensible to drive back to the Glen instead of walking. They found that the clouds were only around the tops of the high mountains, and that it was really a pleasant day, after all, when they reached the valley; and after they had told the story of their expedition, the party scattered itself about the piazzas and rooms of the hotel, and Jack presently went to find Alice, and asked her eagerly why it would not be a good plan to take half their journey that day, and the rest the next, and spend the night somewhere on the road. Then they would have more time in North Conway, for there were some friends there whom they both wished to see.
