politely, saying in odd German, "Good evening, my boys. May you return again to our alp."

When their father told the boys what the man had said, Joe answered quickly, "Oh, thank you! May we come up to your alp some day and help you make your hay?"

And so it was arranged that the boys should climb up to the alpine meadow some day very soon, to help the herdsman make his hay.

They were going to spend two whole weeks by Lake Lucerne at the foot of the mountain, so they would have time to do many interesting things.

After leaving the herdsman and his family, the boys hurried on down the trail. It took them nearly three hours to reach the shore of the lake, where a steamer was waiting to carry them across the water to the city of Lucerne.

It was one of the steamers which the Overall Boys had seen from the top of Mount Rigi that very morning. Away up there it had looked no larger than a plaything, but they now found that it was quite a grown-up boat.
