What do you think of another comparison?
Does not this plain look like an immense battle field piled with the bleaching bones of myriads who had slaughtered each other to a man at the bidding of some mighty Caesar?
What do you think of that lofty comparison, hey ?" "It is quite on a par with the other," muttered Barbican.
"He's hard to please, Captain," continued Ardan, "but let us try him again! Does not this plain look like-- ?" "My worthy friend," interrupted Barbican, quietly, but in a tone to discourage further discussion, "what you think the plain _looks like_ is of very slight import, as long as you know no more than a child what it really _is_!" "Bravo, Barbican! well put!" cried the irrepressible Frenchman.

"Shall I ever realize the absurdity of my entering into an argument with a scientist!" But this time the Projectile, though advancing northward with a pretty uniform velocity, had neither gained nor lost in its nearness to the lunar disc.

Each moment altering the character of the fleeting landscape beneath them, the travellers, as may well be imagined, never thought of taking an instant's repose.

At about half past one, looking to their right on the west, they saw the summits of another mountain; Barbican, consulting his map, recognized _Eratosthenes_.
This was a ring mountain, about 33 miles in diameter, having, like _Copernicus_, a crater of immense profundity containing central cones.
Whilst they were directing their glasses towards its gloomy depths, Barbican mentioned to his friends Kepler's strange idea regarding the formation of these ring mountains.

"They must have been constructed," he said, "by mortal hands." "With what object ?" asked the Captain.
"A very natural one," answered Barbican.
