We passed that place where Nick had stopped Suzanne in the cart, and laughed at the remembrance. We came to Monsieur Gratiot's, for he had bidden us to stay with him. And with Madame he gave us a welcome to warm our hearts after our journey``David,'' he said, ``I have seen many strange things happen in my life, but the strangest of all is that Clark's drummer boy should have married a Vicomtesse of the old regime.

And she was ever Madame la Vicomtesse to our good friends in St. Louis, for she was a woman to whom a title came as by nature's right.

``And you are about to behold another strange thing David,'' Monsieur Gratiot continued. ``To-day you are on French territory.''

``French territory!'' I exclaimed.

``To-day Upper Louisiana is French,'' he answered.

``To-morrow it will be American forever. This morning Captain Stoddard of the United States Army, empowered to act as a Commissioner of the French Republic, arrived with Captain Lewis and a guard of American troops. Today, at noon, the flag of Spain was lowered from the staff at the headquarters. To-night a guard of honor watches with the French Tricolor, and we are French for the last time. To-morrow we shall be Americans.''

I saw that simple ceremony. The little company of soldiers was drawn up before the low stone headquarters, the villagers with heads uncovered gathered round about.

I saw the Stars and Stripes rising, the Tricolor setting.

They met midway on the staff, hung together for a space, and a salute to the two nations echoed among the hills across the waters of the great River that rolled impassive by.

AFTERWORD

This book has been named ``The Crossing'' because Ihave tried to express in it the beginnings of that great movement across the mountains which swept resistless over the Continent until at last it saw the Pacific itself. The Crossing was the first instinctive reaching out of an infant nation which was one day to become a giant. No annals in the world's history are more wonderful than the story of the conquest of Kentucky and Tennessee by the pioneers.
