[Illustration: They pushed off, and the boat was rapidly borne from the shore by the ebbing tide. For a long time the motionless outline of the Indian was seen through the foam of the waves.]
At that instant the Duncan's boat approached, and, gliding into the narrow channel between the sand-banks, grounded on the beach.
"Lady Helena and Miss Grant await you on board," replied the cockswain. "But we have not a moment to lose, my lord, for the tide is beginning to ebb."
The last acknowledgments were given, and Thalcave accompanied his friends to the boat. Just as Robert was about to embark, the Indian took him in his arms and gazed at him tenderly.
"Adieu, my friend, adieu!" cried Glenarvan.
"Shall we ever see each other again?" asked Paganel.
"Who knows?" replied Thalcave, raising his arms towards heaven.
They pushed off, and the boat was rapidly borne from the shore by the ebbing tide. For a long time the motionless outline of the Indian was seen through the foam of the waves. Then his tall form grew indistinct, and soon became invisible. An hour afterwards they reached the Duncan. Robert was the first to spring upon the deck, where he threw himself upon his sister's neck, while the crew of the yacht filled the air with their joyous shouts.
Thus had our travelers accomplished the journey across South America on a rigorously straight line. Neither mountains nor rivers had turned them aside from their course; and, although they were not forced to struggle against the evil designs of men, the relentless fury of the elements had often tested their generous intrepidity to its utmost powers of endurance.
The first moments were consecrated to the happiness of meeting. Lord Glenarvan did not wish the joy in the hearts of his friends to be chilled by tidings of their want of success. His first words, therefore, were,--
"Courage, my friends, courage! Captain Grant is not with us, but we are sure to find him."
It needed only such an assurance to restore hope to the passengers of the Duncan. Lady Helena and Mary Grant, while the boat was approaching the ship, had experienced all the anguish of suspense. From the deck they endeavored to count those who were returning. At one time the young girl would despair; at another she would think she saw her father. Her heart beat quickly; she could not speak; she could scarcely stand. Lady Helena supported her, while Captain Mangles stood beside her in silence. His keen eyes, accustomed to distinguish distant objects, could not discern the captain.
