In en om Java's Paradijs / De Aarde en haar Volken, 1907

The account describes a highland region of Java, portraying rugged volcanic scenery, the great crater Bromo and its association with ritual offerings, and the everyday life, customs and language of mountain communities. It mixes landscape description, local legends and practical travel information, recounting routes, acclimatization stops, and the development of a sanatorium used by visitors. The narrative also records colonial‑era encounters that introduced new crops and gardening techniques, sketches the area's climate and agriculture, and reflects on how natural and built remains preserve an older cultural past.
