'Yes, but suppose the leads lie? The bank would tell you so, and then you'd stir those leadsmen up a bit. There was a ten-foot bank here last trip, and there is only a six-foot bank now. What does that signify?'
'That the river is four feet higher than it was last trip.'
'Very good. Is the river rising or falling?'
'Rising.'
'No it ain't.'
'I guess I am right, sir. Yonder is some drift-wood floating down the stream.'
'A rise starts the drift-wood, but then it keeps on floating a while after the river is done rising. Now the bank will tell you about this. Wait till you come to a place where it shelves a little. Now here; do you see this narrow belt of fine sediment That was deposited while the water was higher. You see the driftwood begins to strand, too. The bank helps in other ways. Do you see that stump on the false point?'
'Ay, ay, sir.'
