was the change from the warm summer air without. But Mr. Bradford said there was no danger if they did not stay too long, or sit down in the glen. At the foot of the wall of rock lay great stones piled one over another; and looking through the spaces between these, the little girls saw masses of ice hard as the rock above, which lay there all the year round. How far below the surface they reached, no one knew; but there must have been a great quantity of ice there, since summer or winter, it never disappeared. Little rills and springs, cold as the ice itself, and delicious to drink, slowly trickled from each end of the glen, but though they ran all summer long, they never seemed to make any difference in the great mass which lay within. The children thought it wonderful, as indeed it was, and were very unwilling to come away when mamma said they had stayed there as long as she thought safe. They were forbidden to go there without some grown person, but this command was scarcely needed by the little girls, since Bessie could not have made her way alone without the help of some stronger hand; and though Maggie thought the glen a great curiosity, she did not like the chill and gloom of the place, and was glad to come out once more into the bright sunshine which met them at the entrance.

And here there was another thing which interested her and Bessie very much. Directly over the little stream which ran from the glen, was a small, neat, wooden building, carefully closed. The children had asked what it was when they passed it the first time, but papa said he did not know; it had been put up since he had been there last. But now they saw Fanny Porter unlocking the door, and Maggie and Bessie ran eagerly forward to ask the use of the little house.

"I'll show you," said Fanny, good-naturedly, and she threw open the door and window shutters, letting in the light and air. "This is our new dairy, Mrs. Bradford," she continued, as the older people came nearer. "Will you not walk in with the other ladies and gentlemen?"

The whole party were well pleased to enter the neat, pleasant-looking dairy. The floor was paved with large flat stones, sloping from the front and back of the building towards the middle, and through the channel thus formed was led the clear, cold stream which ran from the glen. In the icy water stood several great earthen pots, carefully covered. Around the room ran a broad shelf, also of stone, and on this were placed the bright tin pans, most of them now full of milk, and in one corner were two or three churns. The whole dairy was as neat as hands could make it, so it was quite a pleasure to think of milk and butter which should come from such a place.

"Father thought he would make the Ice Glen useful as well as curious," said Fanny Porter. "See, Mrs. Bradford, what this cold water does for our butter;" and taking the cover from one of the stone pots, she handed a wooden spaddle to the lady. Mrs. Bradford pressed it upon the butter, which she found almost as firm and hard as the rock.

"Do you make butter here?" asked Bessie.

"Indeed we do," said Fanny. "I am going to churn now, and if your mother will let you stay, you may see how I do it."

Permission was given, and the grown people went away, leaving Maggie and Bessie with the good-natured Fanny.

"Could you let us help you a little?" asked Bessie.

"Help me?" repeated Fanny, looking with a smile at the tiny figure she was just lifting upon a high stool, the only seat the dairy contained. "I guess you do not know what hard work churning is, do you?"

"Oh, we are accustomed to it," said Bessie. "We have a little churn at home, and we churn water, only it never makes butter."

"No, I suppose not," said Fanny. "And now would you like a drink after your walk?"

The children said they would, and taking down a dipper from the wall, Fanny gave them a drink of the rich, cold milk. After this she poured into the churn a quantity of thick, yellow cream, and putting on the cover, she told Bessie to stand upon the stool and go to work.

But Bessie found churning water in her own little churn at home, was a very different thing from trying to make the butter come with that heavy dasher; she could scarcely stir it, and in a moment she was quite satisfied. Maggie being stronger, pulled the dasher up and down a few times, and did not give up until she was red in the face, and her little hands were smarting with the hard work they were not used to.

The butter did not come by any means as quickly as the children expected, even when Fanny took hold; and, tired of waiting for it, they presently began to amuse themselves with sailing the acorn cups which they had picked up in their walk, in the stream which ran through the dairy. It was great fun to launch them at the upper end, and watch them as they floated down, now driven against a butter pot, now passing round it, and at last carried out at the farther end of the dairy.

By the time they had had enough of this amusement, the kind Fanny said the butter had come, and taking off the cover of the churn, she dashed in a quantity of cold water from that convenient little stream, having first lifted Maggie and Bessie upon the shelf, so that they might be high enough to look down into the churn. The butter which was floating about in tiny lumps, instantly collected together, and bringing a dish, Fanny scooped it out with a wooden ladle, and laid it in a rich, creamy mass. Then she threw in a little salt, and having worked and pressed it till it was free from every drop of water, she packed it away in a stone pot, and set that with the others in the running water. The children watched her with great interest until all was done, and were still standing by while she skimmed the cream from some of the many pans of milk, when Jane came to tell them their mamma wished them to come back to the house.
