It will be remembered that Harriet was unable to see over the deckhouse from where she stood when guiding the craft.

She could see only by leaning out on either side.
They entered the narrow channel very slowly.

But no sooner had they gotten well in than a cry from Tommy Thompson told them that the little lisping girl was in trouble.
Tommy had been swept from her feet by the foliage.

Not only that, but in floundering about she had rolled over the side of the boat.

A mighty splash and a second cry gave additional evidence that Tommy was in further difficulties.
"Help me! I'm in the water!" she screamed, coming up sputtering and coughing.
"Stay there and push," answered Harriet, laughing so that she bumped the nose of the houseboat into the bank on the right side of the creek.
