Away they went, down the slope and over the bottom land to the mouth of the creek, where the boat was moored. Soon they glided out from the shore under Frank's steady stroke. "We will go up on this side, where it is easier to row," he said. "The current is on the other side next to the bank." "Why do you suppose the current is over there?" asked Uncle Robert. "I don't know," said Frank. "Last spring we had a big flood, and the current was so strong that it took away a lot of earth from that bank. The earth fell down into the river and was carried away. Mr. Davis lost a good deal of land." "Tell me about the flood, Frank," said Uncle Robert. "Last March the ice broke up in the river and went tearing downstream in great blocks," began Frank. "Just below the dam, between the island and that shore," pointing to the woods, "it piled up until there was a big ice jam. You could cross over to the island on foot. Then the water began to rise until it was nearly even with the top of the dam. At first it went round close to the ridge. You see the land is lower there. The part of our cornfield next to the river was an island. Then the water rose higher, and spread all over the bottom land. It made the mouth of the creek close to the slope, and the water came up around the trunks of the trees. "On the other side, where the current is, it didn't get over the bank, but it tore away lots of earth. Three big trees fell into the water and were carried down the river. Ever so many trees came down. Peter and I caught a lot and piled them up for firewood." "Don't you remember, Frank," said Susie, "two or three sheds came down, too?" "The miller thought it would carry away the mill," said Donald. "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. "When we go in swimming we can wade out here a long ways before we go over our heads," said Donald. "I wish I could swim," said Susie. "You should learn," said Uncle Robert. "The boys could easily teach you."
