"We are now regularly in the country of the moon," said Doctor Ferguson, "for it has retained this name, which was anciently bestowed upon it, doubtless, because the moon has been always worshiped here. It is indeed a magnificent district, and it would be difficult to find a more beautiful vegetation."
"That sort of thing would not be natural near London," said Joe, "but it would be very pleasant. Why are all those lovely things reserved for these barbarous countries?"
