“It is a wise old saw that warns us not to whistle until we are out of the woods.”

1860s, The Good Fight (1865)
Context: It is a wise old saw that warns us not to whistle until we are out of the woods. But, as we climb the Alps and, emerging from the morass and forest, set once more the sun and the broad landscape, we may fairly shout and sing, although we are still toiling on, and are yet far below the pure peaks towards which we go. In our Revolution, a man who saw distinctly, as we can now see, that the triumph of Great Britain would have imperiled constitutional liberty everywhere, surely had a right to rejoice over the victory of Saratoga, though it was not the end of the war. The battle did not end the war, indeed. The Tories sneered and bade the Yankees wait. They did wait. They waited from Burgoyne's surrender at Saratoga to Comwallis's surrender at Yorktown. Yankee pluck, as usual, waited until it won, as in later days it waited from Bull Run to Richmond. The battle of Saratoga was a skirmish compared with our later battles, but it was a fatal blow to Tory supremacy upon this continent. It was a gleam of sunshine in which it was right to shout and sing, for it was another great gain in the 'Good Fight of Man'.
