TIME AND CHANGE 



a favorite trout-stream of my native hills, and the 

 old Cambrian plateau that edges the inner chasm, 

 as we looked down upon it from nearly four thou 

 sand feet above, looked like the brown meadow 

 where we played ball in the old school-days, friendly, 

 tender, familiar, in its slopes and terraces, in its tints

 tiary, and yet behold the duration of that yes 

 terday as here revealed, probably a million years or 

 more ! We can no more form any conception of such

 turing the air, the rains, the frost, the sunshine 

 are as active now as they ever were; but their activ
