Famous quotes containing the word salt:
“Come, dear children, let us away;
Down and away below!
Now my brothers call from the bay,
Now the great winds shoreward blow,
Now the salt tides seaward flow;
Now the wild white horses play,
Champ and chafe and toss in the spray.”
—Matthew Arnold (1822–1888)
