Half a mile from the spot it became evident, even to the passengers clustered forward on the cabin-deck, that the sycamore had remained quite near to its old home, for a long, rough ripple was seen directly across the line of the channel.

Then arose the question as to how much water was on top of the tree, and whether any bar had had time to accumulate.

The steamer was stopped, the engines were reversed and worked by hand to keep the Bennett from drifting down-stream, a boat was lowered and manned, the Chums forming part of her crew, and the second officer went down to take soundings; while the passengers, to whom even so small a cause for excitement was a godsend, crowded the rail and stared.
