"My father's documents!" cried Dick.

"The letters!" shrieked Louis Vorlange. Then he made a sudden leap to secure them, but Pawnee Brown was too quick for him. The scout turned to the captain of cavalry standing near.

"You had better arrest him before he tries to escape."

"They shall not arrest me!" came from Louis Vorlange's set lips. "Clear the way!"

Like a flash his pistol came up and he fired into the crowd, which parted in surprise and let him pass. But not more than ten steps were covered when Pawnee Brown caught him by the arm and threw him headlong to the ground. At the same time the prison sentry fired, and Vorlange was mortally wounded in the side.

"I'll not forget you!" he cried to Pawnee Brown. "But for you I would have lived in clover the balance of my life!" Then he fell into a faint from which he recovered presently, to linger for several days in terrible anguish, dying at last in convulsions.

With the death of Vorlange we bring our story to a close. By what was said during the man's last hours on earth, Mortimer Arbuckle was entirely cleared of the cloud which had hung over his honorable name. Soon after this his right mind came back to him and to-day he is as well and happy as it is possible to imagine.

Whatever became of Stillwater and Juan Donomez is not known.

With the truce declared by the actions of the authorities at Washington and the word given by Pawnee Brown that no attempt should be made to enter Oklahoma for the present, it was not deemed advisable to hold either Dick or Rasco longer, and the two were given their freedom, to journey at once to Honnewell, in company with the great scout and Nellie Winthrop.

From Honnewell, Dick rode post haste to carry the glad news to his father. A scene followed which no pen can describe, a scene so sacred to the two it must be left entirely to the imagination of the reader. Never was a man more proud of his son than was Mortimer Arbuckle of Dick, or more grateful than was the mine-owner to Pawnee Brown for his courageous and marvelous work in clearing up the mystery.
