"See it pour! And just hear the thunder!" said Joe, looking out of the car window. "It sounds as if giants were rolling rocks down the mountain sides. I hope they will not hit our train."

"Look! The train is stopping," said Jack. "The conductor says we must all get out here and take another train. How can we change while it is pouring so hard!"

The rain was really pouring down so fast that umbrellas were of no use at all. But the Overall Boys ran to the end of the platform and climbed into the high front seat of a queer little car.

It was certainly the strangest car the boys had ever seen. It was built so that one end was much higher than the other end, and people had to go up some steps to get into it.

In a few moments the little train was moving slowly up the steep track.

"Where do you suppose we are going?" cried Joe. "I believe we are climbing right up the side of a mountain. My! How it rains! I guess we are up among the clouds."

"We shall soon be up above the clouds," said Jack. "We are climbing Mount Rigi. We are going to stay all night on the mountain, too."

And so it happened. The train was soon pulled up the steep mountain side until it was above the rain and the wet clouds. The sun was shining brightly up there, but the valleys below were covered with a thick white blanket.

At last the sun and the wind began to carry great pieces of the cloud blanket high into the sky. Through the openings in the clouds, below them the boys could see tiny villages and blue lakes.

And away down below, hanging in the soft white clouds, was a rainbow—all red and orange and yellow and green and blue and violet.

"Look! We are above the rainbow bridge!" cried Joe. "If only I could jump over on it, I could slide right down to the earth again."

"Why, you are on the earth now," said Jack.

"Oh, so I am! But isn't it wonderful up here!"

The boys watched the fluffy clouds blow far away, carrying the lovely rainbow with them. And they watched the great red sun drop down behind the snow-covered mountains in the west.

Suddenly Joe cried, "Those mountains are on fire, Jack! Look! How can they burn when they are all covered with snow?"

"It looks as if the red-hot sun had set the world on fire this time, doesn't it?" cried Jack.

But it hadn't, though the mountains were rosy for a long time after darkness had come in the deep valleys below. The great round moon climbed slowly up the sky, and millions of stars peeped down at the boys.

They had never been so near the stars before. They were almost six thousand feet nearer than they were on the ocean steamer, and six thousand feet are more than a mile.

At last the boys were so tired they went into a small hotel, high on the mountain, and were soon tucked away in two narrow white beds. For a few moments they lay very still, then Joe whispered, "Jack, do you hear those bells tinkling, out on the mountain side?"

And Jack whispered, "Yes, Joe. They are cow bells. You know five thousand cows are pastured on this mountain in the summer time."

"From the sound, I guess they all wear bells, too," said Joe. "Isn't it lovely! The bells make me so sleepy."
