37. And ever as we sailed, our minds were full Of love and wisdom, which would overflow _4775 In converse wild, and sweet, and wonderful, And in quick smiles whose light would come and go Like music o'er wide waves, and in the flow Of sudden tears, and in the mute caress-- For a deep shade was cleft, and we did know, _4780 That virtue, though obscured on Earth, not less Survives all mortal change in lasting loveliness. 38. Three days and nights we sailed, as thought and feeling Number delightful hours--for through the sky The sphered lamps of day and night, revealing _4785 New changes and new glories, rolled on high, Sun, Moon and moonlike lamps, the progeny Of a diviner Heaven, serene and fair: On the fourth day, wild as a windwrought sea The stream became, and fast and faster bare _4790 The spirit-winged boat, steadily speeding there. 39. Steady and swift, where the waves rolled like mountains Within the vast ravine, whose rifts did pour Tumultuous floods from their ten thousand fountains, The thunder of whose earth-uplifting roar _4795 Made the air sweep in whirlwinds from the shore, Calm as a shade, the boat of that fair child Securely fled, that rapid stress before, Amid the topmost spray, and sunbows wild, Wreathed in the silver mist: in joy and pride we smiled. _4800 40. The torrent of that wide and raging river Is passed, and our aereal speed suspended. We look behind; a golden mist did quiver When its wild surges with the lake were blended,-- Our bark hung there, as on a line suspended _4805 Between two heavens,--that windless waveless lake Which four great cataracts from four vales, attended By mists, aye feed; from rocks and clouds they break, And of that azure sea a silent refuge make. 41. Motionless resting on the lake awhile, _4810 I saw its marge of snow-bright mountains rear Their peaks aloft, I saw each radiant isle, And in the midst, afar, even like a sphere Hung in one hollow sky, did there appear The Temple of the Spirit; on the sound _4815 Which issued thence, drawn nearer and more near, Like the swift moon this glorious earth around, The charmed boat approached, and there its haven found.
