ties have been smoothed away by the same agency which has planed 

 the rocks everywhere. Only the roches moutonnees have been left 

 furrowed and scratched upon one side, whence the abrading and 

 engraving tool advanced, but vipon the other unscored, and hidden 

 beneath a tail of fragments ground from their opposite slopes. The 

 significance of this we shall see later. 



Thus, imperfectly described, we have reviewed the most prominent 

 features of a comparatively modern period, viz., the widely-grooved 

 and polished condition of northern rocks, especially hard-grained rocks, 

 which retain these impressions ; the occurrence of wandering bowl- 

 ders, transported longer or shorter distances from their primitive 

 sites, and the detrital matter from continental abrasion deeply bury- 

 ing the rocky face of the country, and in ridges, mounds, and sheets, 

 extending east and west, and along the greater water-courses, 

 stretching itself down into the Southern States in irregular tails and 

 projections. We will now venture to examine the theories advanced 

 to explain these singular phenomena, and describe that one which 

 best accounts for these facts, with many correlated ones, offering an 

 hypothesis which rationally secures their complete and harmonious 

 agreement.

TEACHINGS OF A DAY. 



By LOUISA S. BEVINGTON. 

 MORNING. 



"TTTHAT'S the text to-day for reading 

 V V Nature and its being by ? 



There is effort all the morning 

 Through the windy sea and sky. 



All, intent in earnest grapple, 



That the All may let it be : 

 Force, in unity, at variance 



"With its own diversity. 



Force, prevailing unto action : 

 Force, persistent to restrain : 



In a twofold, one-souled wrestle, 

 Forging Being's freedom-chain. 



Frolic ! say you when the billow 

 Tosses back a mane of spray ? 



No ; but haste of earnest effort ; 

 Nature works in guise of play.
