"But never mind the Selenites now.

Observe _Eratosthenes_ as long as you have the opportunity." "Which will not be very long," said M'Nicholl.

"He is already sinking out of view too far to the right to be carefully observed." "What are those peaks beyond him ?" asked Ardan.
"The _Apennines_," answered Barbican; "and those on the left are the _Carpathians_." "I have seen very few mountain chains or ranges in the Moon," remarked Ardan, after some minutes' observation.
"Mountains chains are not numerous in the Moon," replied Barbican, "and in that respect her oreographic system presents a decided contrast with that of the Earth.

With us the ranges are many, the craters few; in the Moon the ranges are few and the craters innumerable." Barbican might have spoken of another curious feature regarding the mountain ranges: namely, that they are chiefly confined to the northern hemisphere, where the craters are fewest and the "seas" the most extensive.
For the benefit of those interested, and to be done at once with this part of the subject, we give in the following little table a list of the chief lunar mountain chains, with their latitude, and respective heights in English feet.
