From yon blue heavens above us bent The gardener Adam and his wife Smile at the claims of long descent. Howe'er it be, it seems to me, 'Tis only noble to be good. Kind hearts are more than coronets, And simple faith than Norman blood.

Then, with that faint fleeting smile playing about his lips, he faced the firing squad; erect and motionless, proud and disdainful,Walter Mitty, the undefeated, inscrutable to the last.

If I laugh on that particular day I become so filled with Laughing Gas that I simply can't keep on the ground. Even if I smile it happens.The first funny thought, and I'm up like a balloon. And until I can thinkof something serious I can't get down again.

  MrWigg, Mary Poppins's uncle.The'particular day' is when his birthday falls on a Friday. Mary Poppins, ch.3.

Even so for me a vision sanctified The sway of death; long ere my eyes had seen Thy countenanceöthe still rapture of thy mienö When thou, dear Sister! wert become death's bride: No trace of pain or languor could abide That changeöage on thy brow was smoothedöthy cold Wan cheek at once was privileged to unfold A loveliness to living youth denied. Oh! if within me hope should e'er decline, The lamp of faith, lost Friend! too faintly burn; The may that heaven-revealing smile of thine, The bright assurance, visibly return: And let my spirit in that power divine Rejoice, as, through that power, it ceased to mourn.
