Which are the clouds, and which the mountains? See, br They mix and melt together! Yon blue hill br Looks fleeting as the vapors which distill br Their dews upon its summit, while the free br And far-off clouds, now solid, dark, and still, br An aspect wear of calm eternity. br Each seems the other, as our fancies will -- br The cloud a mount, the mount a cloud, and we br Gaze doubtfully. So everywhere on earth, br This foothold where we stand with slipping feet, br The unsubstantial and substantial meet, br And we are fooled until made wise by Time.
