"He promised her in the letter that if she would come, he would take her to see the grand Cologne cathedral. He said thousands of strangers visit it every year, because every one knows it is one of the most beautiful buildings in all Europe.
"Then he said she should also see the Church of Saint Ursula, where the bones of the eleven thousand maidens can still be seen in their glass cases."
"Do you know the story of St. Ursula, Gretchen?" asked her father.
"Yes, indeed, sir. Ursula was the daughter of an English king. She was about to be married, but she said that before the wedding she would go to Rome on a pilgrimage.
"Eleven thousand young girls went with the princess. On her way home she was married, but when the wedding party had got as far as Cologne, they were attacked by the savage Huns. Every one was killed,—Ursula, her husband, and the eleven thousand maidens. The church was afterward built in her memory. Ursula was made a saint by the Pope, and the bones of the young girls were preserved in glass cases in the church."
"Did Frau Braun tell of anything else her brother wrote?" asked her mother.
"He spoke of the bridge of boats across the river, and said she would enjoy watching it open and shut to let the steamers and big rafts pass through. And he told of the Cologne water that is sold in so many of the shops. It is hard to tell which makes the town most famous, the great cathedral or the Cologne water."
"Father, how was the bridge of boats made?" asked Bertha.
"The boats were moored in a line across the river. Planks were then laid across the tops and fastened upon them. Vessels cannot pass under a bridge of this kind, so it has to be opened from time to time. They say it is always interesting to see this done."
"Yes, Frau Braun said she would rather see the bridge of boats than anything else in the city. She has already begun to plan how she can save up enough money to make the trip."
