TOUR FROM SOUR ABAYA, THROUGH KEDIRI, BLITAR, AN- 
TANG, MALANG AND PA8SURUAN, BACK TO SOURABAYA.* 
By Jonathan Rigg, Esq., Member of the Batavian Society of Arts 
and Sciences. 
The town of Kediri is situated much nearer the western 
verge of the plain, and the group of the Willis mountains, 
than the ranges of the Klat and Kawi, which form the 
eastern boundary, and whose towering peaks are only 
occasionally seen in the haze, at this time of the year. Ihe 
Gunung Kolotok is an outlying mass of the Willis and 
between it and the Kediri river, being separated from this 
latter by a flat of sawahs, a couple of pauls broad, and from 
the former by a low ridge and valley. It is perhaps not 
higher than a couple of thousand feet, and it is the parallel 
of so many subordinate hills which are seen at the foot of the 
volcanoes of Java. The Kolotok is covered with forest and 
jungle, and probably derives its name, from its resemblance 
to an instrument so called, and which is a wooden bell hung 
round the neck of the buffalo ; at least its outline, as seen, 
more especially by moonlight, immediately suggests the 
idea ; a central eminence rising from the two broad shoulders 
answers to the part through which the strap or cord is 
passed. It is in this Gunung Kolotok that is situated the 
well-known grotto of Sello Mangleng. The kindness of the 
Resident supplied us in the afternoon with horses to visit 
this piece of antiquity. A straight road from opposite the 
Residency leads across the sawahs to near the foot of the 
hill, and a broad bridle way then conducts through the 
jungle to the grotto, which is within three pauls of Kediri. 
On a slightly rising ground, is seen a bluff rock overhung 
with trees and shrubs, above which towers the Gunung 
Kolotok. About a quarter of the way up this rock are seen 
two apertures or doorways piercing the solid rock, each 
about five feet square, and approached sideways by a rugged 
ledge of the rock from the northward, and which appears to 
have been intentionally left in its original rude state. By 
the two doorways, which are close together, admittance is 
gained into two chambers which again communicate with 
each other by an opening in the party wall. The southern 
chamber is the larger of the two, being 16 feet deep and 10
