 "Meeting at Night" The gray sea and the long black land; And the yellow half-moon large and low; And the startled little waves that leap In fiery ringlets from their sleep, As I gain the cove1 with pushing prow2, And quench its speed i 3 the slushy sand. Then a mile of warm sea-scented beach; Three fields to cross till a farm appears; A rap at the pane4, the quick sharp scratch And blue spurt of a lighted match, And a voice less loud, thro 5 its joys and fears, Than the two hearts beating each to each. . Robert Browning 1 A cove is a small inlet from the sea. 2 A prow is the front end of a boat. 3 i is short for in. 4 Pane refers to a windowpane. 5 Thro is short for through.
