As the boat glided by this place, Rollo and Lucia saw some ladies and gentlemen sitting in the summer house. The gentlemen took off their hats and bowed to Mr. and Mrs. Holiday as they passed by.
Next the boat came to a place where there was a low parapet wall along the shore, and behind it were to be seen the heads of a number of men who seemed to be sitting at tables, and drinking coffee or beer.
"Here is a good place to land," said Lucia.
"No," said Rollo; "this seems to be some sort of public place, full of men. We had better go a little farther."
So Rollo steered on, keeping all the time at just a safe distance from the shore. The water was most beautifully transparent and clear, so that all the pretty stones and pebbles on the bottom could be seen very distinctly at a great depth.
"What pretty water!" said Lucia.
"Yes," said Rollo, "it is so clear."
"What makes it so clear?" asked Lucia.
"Because the lake is so long," said Rollo, "and this is the lower end of it, and the water has time to settle. At the other end, where the water comes in, it is not so clear. This is the end where the water runs out."
