"Thermopylae was by the sea-shore," said Alice.

"Now, I should imagine," said Sam, pointing to the natural glacis formed by the decay of the great wall which they had seen fronting them as they came up, "that a few determined men with rifles, posted among those fern-trees, could make a stand against almost any force."

"But, Sam," said Jim, "they might be cut up by cavalry. Horses could travel right up the face of the slope there. Now, suppose a gang of bushrangers in that fern-scrub; do you think an equal number of police could not turn them out of it? Why, I have seen the place where Moppy's gang turned and fought Desborough on the Macquarrie. It was stronger than this, and yet—you know what he did with them, only kept one small one for hanging, as he elegantly expressed it."

"But I ain't talking of bushrangers," said Sam. "I mean such fellows as the Americans in the War of Independence. See what a dance they led our troops with their bushfighting."

"I wonder if there will ever be a War of Independence here," said Alice.

"I know which side I should be on, if there was," said Sam.

"Which would that be?" asked Jim.

"My dear friend," said Sam, testily, "how can you, an officer's son, ask me, an officer's son, such a question? The King's (I beg pardon, the Queen's) side, of course."

"And so would I," said Jim, "if it came to that, you know."

"You would never have the honour of speaking to your sweet sister again, if you were not," said Alice.
