whore tlie Tji-Tarum, raging along in its entire volume, is 

 compelled to pass through a gate of rock not above 12 feet 

 wide. A frail-looking bamboo ladder, with Rotang ropes 

 suspended on either side at a dizzy elevation above, leads 

 down the perpendicular walls of this stone portal. 



''■ On the morning of the 22nd we visited Tjuruk-Almion, 

 the finest waterfall of the Tji-Tarum, which is here precipi- 

 tated over a precipice of greenstone forty feet in height, and 

 thence, after passing the steep basaltic chain of Gunung- 

 Lanang, we descended from a height of 2653 Paris feet, into 

 the deepest part (990 Paris feet above sea-level) of the chasm 

 formed by volcanic eruption in the mountain Sangjang- 

 Holut, where close to the steep broken rim, and in juxtaposi-

 the perpendicular sandstone banks of the river leave a 

 passage only 10 feet in width. 



" The same day we resiched the little village of Gua, at 

 the foot of the northern side of Gunmig Nungnang, an 

 enormous mass of limestone, whose steep sides form a 

 portion of the extensive limestone barrier, which bounds 

 the table-land of Radjamandala to the southward. Gunung 

 Nungnang is traversed by fissures and clefts from top to 

 bottom, in which the Salangan swallow builds edible nests, 

 which the natives gather for the Regent, not without peril to 

 life.
