A travelogue recounting a journey from the Algerian coast inward toward the Sahara, progressing by train, horseback and camel across plateaus, ksour and oases. It blends practical itinerary detail with evocative descriptions of light, heat and night, attentive scenes of markets, towns and water channels, and observations of local customs and daily life. The narrative contrasts crowded, lively railway and market moments with the solitude of desert plains and caravan travel, offering reflections on equipment, movement and landscape rhythms. Photographic illustrations accompany and reinforce the places and moments described.
