"Very pretty indeed. Give way!"
"But won't it tip over?" cried Mary, as the boat darted out of the cove.
"Oh, no; there is not the least danger."
"And you guide it with those strings?" asked the wondering girl.
"Yes; they are fastened to that crosspiece, you see; and when I pull them, it moves the rudder."
"What is the rudder, Frank?"
"You can see only the upper end of it; but it is a flat piece of wood, which acts upon the water, and turns the boat," replied the obliging coxswain, illustrating his explanation by means of his hands.
"Oh, my! how swift it goes!"
"Not very fast now."
"Why, it goes like a racehorse."
