Dick Sands the Boy Captain by Jules Verne — Read

The morning of the 18th dawned, the day on which, according to Harris's prediction, the travellers were to be safely housed at San Felice. Mrs. Weldon was really much relieved at the prospect, for she was aware that her strength must prove inadequate to the strain of a more protracted journey. The condition of her little boy, who was alternately flushed with fever, and pale with exhaustion, had begun to cause her great anxiety, and unwilling to resign the care of the child even to Nan his faithful nurse, she insisted upon carrying him in her own arms. Twelve days and nights, passed in the open air, had done much to try her powers of endurance, and the charge of a sick child in addition would soon break down her strength entirely.

Dick Sands, Nan, and the negroes had all borne the march very fairly. Their stock of provisions, though of course considerably diminished, was still far from small. As for Harris, he had shown himself pre-eminently adapted for forest-life, and capable of bearing any amount of fatigue. Yet, strange to say, as he approached the end of the journey, his manner underwent a remarkable change; instead of conversing in his ordinary frank and easy way, he became silent and preoccupied, as if engrossed in his own thoughts. Perhaps he had an instinctive consciousness that "his young friend," as he was in the habit of addressing Dick, was entertaining hard suspicions about him.
