Page 219 - Rolls fair and placid : where collected all, In one impetuous torrent, down the steep It thundering shoots, and shakes the country round. At first, an azure sheet, it rushes broad ; Then whitening by degrees, as prone it falls, And from the loud-resounding rocks below Dash'd in a cloud of foam, it sends aloft A hoary mist, and forms a ceaseless shower.
Page 270 - My eyes are dim with childish tears. My heart is idly stirred, For the same sound is in my ears Which in those days I heard. Thus fares it still in our decay : And yet the wiser mind Mourns less for what age takes away Than what it leaves behind.
