getting off after two hours' delay.

For the first few miles our path lay over a country cleared for
rice-fields, consisting entirely of small but deep and sharply-
cut ridges and valleys without a yard of level ground. After
crossing the Kayan river, a main branch of the Sadong, we got on
to the lower slopes of the Seboran Mountain, and the path lay
along a sharp and moderately steep ridge, affording an excellent
view of the country. Its features were exactly those of the
Himalayas in miniature, as they are described by Dr. Hooker and
other travellers, and looked like a natural model of some parts
of those vast mountains on a scale of about a tenth--thousands of
feet being here represented by hundreds. I now discovered the
source of the beautiful pebbles which had so pleased me in the
riverbed. The slatey rocks had ceased, and these mountains seemed
to consist of a sandstone conglomerate, which was in some places
a mere mass of pebbles cemented together. I might have known that
such small streams could not produce such vast quantities of
well-rounded pebbles of the very hardest materials. They had
evidently been formed in past ages, by the action of some
continental stream or seabeach, before the great island of Borneo
had risen from the ocean. The existence of such a system of hills
and valleys reproducing in miniature all the features of a great
mountain region, has an important bearing on the modern theory
that the form of the ground is mainly due to atmospheric rather
than to subterranean action. When we have a number of branching
valleys and ravines running in many different directions within a
square mile, it seems hardly possible to impute their formation,
or even their origination, to rents and fissures produced by
earthquakes. On the other hand, the nature of the rock, so easily
