"The water looks pretty clear now. How did it look then?" asked Uncle
Robert.
"At first it was clear," said Frank. "Then it got just like coffee."
"That was the dirt in the water," said Donald.
"When the water went down," continued Frank, "the bottom land was all covered with the stuff the river left. Father says the dirt it brought makes the land better."
"What do you suppose made the freshet?" asked Uncle Robert.
"Oh, they said it was the snow melting, away up the river," answered
Donald. "The snow was gone here, but we had lots of rain."
"Where is the deepest part of the river?" asked Uncle Robert.
"It is quite deep on the other side," said Frank, "but it is shallow over here. Farther down it is deeper in the middle."
"Where is the current down there?" asked Uncle Robert.
"In the middle of the river," said Frank.
