So the Overall Boys had their first sail on lovely Lake Lucerne, the most famous lake in all the world.

The sun went down in a glory of color behind the city of Lucerne at the end of the long lake, and the great, round moon came hurrying up, eager to lend her light to this beautiful part of the world while the sun was away.

It was a wonderful evening. It was almost as wonderful as the evening before, when the boys had been up above the clouds on Mount Rigi.

To-night they were very tired after the long tramp down the mountain. They were too tired to look around much as they were driven quickly along the brightly lighted streets and up the hill to their boarding place.

But in the morning they were ready for anything. The first thing to interest them was breakfast. Jack led the way down the stairs to the large dining room, but it was empty. There was nothing to eat on any of the long tables.

"Oh, dear! We are too late," cried Joe. "I shall starve before noon. I know I shall."

"No, you won't," said Jack. "Look out there under the trees. The people are having a breakfast party."

"Oh, my!" cried Joe. "Are we going to eat out there, too? I hope so!"

"Father and mother are waiting for us over by the tall rose bushes," said Jack. "We can have a little table all to ourselves."

"Is it really a party, or is it just breakfast?" asked Joe.

"I expect it is just breakfast," said Jack. "Mother has said that people here in Switzerland eat out of doors whenever they can."

"Oh, goody! let's have our breakfast out here every morning," said Joe.

And so they did. Every morning when it did not rain, the Overall Boys had their breakfast of rolls and honey and hot chocolate on a small, round table in the rose garden.

It was lots of fun. It was almost as good as a real picnic. Each morning while they were eating, they planned what they should do during the rest of the day.

Some days they spent the forenoon visiting interesting little shops. They liked to watch the pretty Swiss girls at work on their fine embroidery. These girls, dressed in their quaint Swiss costumes, often sat on the sidewalk in front of their shops while working.

But the boys liked best the carved wood shops. Sometimes they saw boys, not much older than themselves, carving jumping-jacks and bears and queer little dwarf men out of blocks of pear wood.

Many Swiss boys learn wood carving when they are quite young, so they can earn their living in that way when they are grown up.

The Overall Boys coaxed their father to buy a fine carved bear to take home with them. The bear was as tall as Joe. He sat on his hind legs, crossing his fore paws in front of him, and he looked as if he might growl any minute.

The boys' mother said the bear should stand by the front door at home, where he could hold umbrellas for people when they came to call.

"What fun we shall have when we introduce the Sunbonnet Babies to Mr. Bear!" said Joe.

"I know a fine way to do it," said Jack. "We will stand him under the big maple tree in the back yard at home. Then, the first time Molly and May come to see us, we will take them out to meet our new playmate."

"Oh, that will be great!" shouted Joe. "I can almost hear Molly and May scream now."

"Let's visit the cuckoo shop," said Jack one afternoon. "And let's try to be there when the cuckoos all come out."

"Well, then, let's go now," said Joe. "It is ten minutes of five. We shall have just time to get there before the clocks begin to strike and the cuckoos begin to call for five o'clock."

So Jack and Joe hurried down the street into the old, old part of the city. They found the little shop just in time. An old man standing in the doorway invited the boys to go in, and of course they accepted.

On the walls around the small room hung many beautiful brown clocks of all sizes. They were very different from American clocks. These clocks looked like tiny Swiss houses or chalets. There was a round clock face in the front of each chalet, and two long swinging arms hanging down below. But the clocks were all saying, tick, tick, tick, tick, just as American clocks do.

"Now watch!" cried Joe. "The doors are beginning to open. Here come the cuckoos."

And sure enough, as the boys stood looking at the clocks, a little door near the top of each swung quickly open and a tiny cuckoo bird stepped out and flapped its wings.

The clocks all began striking and the cuckoos began calling just like this:—One, cuckoo; two, cuckoo; three, cuckoo; four, cuckoo; five, cuckoo.

It was five o'clock. The cuckoo birds folded their wings and stepped quietly back into their tiny houses. The doors closed quickly in front of them and all was still once more, except for the tick, tick of the many clocks.

"We just must buy one of those cuckoo clocks to take back to America with us," said Joe.

"We must buy two of them," said Jack. "We must take one to Molly and May. They will think it is splendid."

"Let's ask father about it," said Joe. "I know he will tell us to buy one for the Sunbonnet Babies and one for Tim and Ted."

"I am going home to supper now," said Jack. "This is Saturday, and there are fireworks on the shore of the lake every Saturday evening, you know."

"Oh, so there are!" cried Joe. "I had almost forgotten about them. Let's hurry."
