W. E. Hardenburg, The Putumayo, the Devil's Paradise
“ But in the persecuted districts of Latin America native labour is practically being hounded off the face of the earth.The Putumayo atrocities were first brought to public notice by an American engineer and his companion, Messrs. Hardenburg and Perkins, and the interesting narrative by the former of their travels upon the Putumayo River forms a large part of the subject of this book. Mr. Hardenburg and his companion suffered great hardships and imprisonment at the hands of the Peruvian agents of the rubber company on the Putumayo, and barely escaped with their lives. ”
