was due to the axis having become oblique, and to the 

 depression of the land in high latitudes far below its 

 present level. The cooler climate that followed the 

 Champlain was due to an upward movement compara- 

 tively local in extent. Subsequent changes have pro- 

 duced the climate of to-day. 



I have not thought it best to speak of other theories. 

 Dr. Croll, in his Climate and Time, has collected all 

 the most important, and pointed out their absolute 

 failure. As for his own theory, I have shown in an ar- 

 ticle in Penn Monthly what seem to me insuperable ob- 

 jections to it. I add here only this : Dr. Croll utterly 

 ignores the two questions, which, with that of warmth, 

 make up the problem of geological climate, and, conse- 

 quently, leaves unsolved what seems to me the most per- 

 plexing part of the question.

SATURN. 



BY PROF. MARIA MITCHELL. 



To the eye, Saturn is far less conspicuons than Jupiter. 

 It is farther from us, it is smaller, its color less ruddy. 

 It might easily be taken for one of the countless stars. 



The first look at it, with a telescope, is an unexpected 

 delight.
