Soeroengaii was the only one of the larger mountains south of Toba 

 Lake that I could botanize clear to the top, and its possibilities I 

 barely scratched. 



4. Two trips were made to the Karo plateau at the north end of 

 Toba Lake, where the U. S. Rubber Co. maintains bungalows at 

 Berastagi. From Berastagi I botanized the two volcanoes, Si Naboen 

 and Si Bajak, as well as the lesser mountains, Deleng Piso-Piso and 

 Deleng Baroes and the hills, Deleng Koetoe and Deleng Singkoet. 



Fig. 116. — Panapparan, a mountain village on Tor Dabolon, above the 

 cliffs. The water from the higher levels is led to the rice terraces, which are 

 a marvel of beauty whether green with the young plants or golden with the 

 harvest. In the left background the summit of Dolok Si Riaria. 



I collected ample material of several of Ridley's plants, which will 

 be of value in interpreting his work, and also got many plants that 

 will probably be new to the flora. 



I stayed in Sumatra a little over six months, and brought back 

 nearly 2,400 numl^ers, with many duplicates. At Loendoet my dry- 

 ing shed was destroyed by fire, with loss of many specimens and 

 most of my equii)mcnt. It took some improvising to take care of the 

 collections during a few days following the fire, but work was hardly 

 interrupted.
