"You have a fine vessel, my lord."

"A good one, too," replied Glenarvan.

"How many tons' burden is she?"

"Two hundred and ten."

"Shall I be greatly mistaken," added Ayrton, "if I say that the Duncan can easily make fifteen knots an hour at full speed?"

"Say seventeen," interposed the captain, "and you will be nearer right."

"Seventeen!" cried the quartermaster: "why, then, no man-of-war, not even the best, could overtake her."

"Not one," said the captain. "The Duncan is a real racing yacht, and is not to be beaten in any way."

"Not even in sailing?" asked Ayrton.
