"That's the 'Achilles'; brought to; with her main topsails laid aback, and her fore topsails full; ready for action."

"I do not know what are topsails or fore topsails," said Dolly.

The midshipman explained; to illustrate his explanation sketched lightly another figure of a vessel, showing more distinctly the principal sails.

"And this is the 'Achilles,'" said Dolly, recurring to the principal design. "You have put her a great way off from the enemy, it seems to me."

"No. Point blank range. Quite near enough."

"Oh, what is 'point blank range'?" cried Dolly in despair. Her new friend smiled, but answered with good-humoured patience. Dolly listened and comprehended.

"Then, if this were an enemy, and that the 'Achilles,' and within point blank range, you would load one of these guns and fire at her?"

The midshipman shook his head. "We should load up all of them—all on that side."

"And five them one after another?"

"As fast as we could. We should give her a broadside. But we should probably give her one broadside after another."
