aspect than those described above - as witnessed by the less broken and flatter slopes, the wider ridges, the meandering brooks along the extensive valleys; steeply inclined mountainsides or gaping gorges are rare. Accordingly, agriculture encroached over a considerably larger area here than in the Diamond Range. It is especially in the neighbourhood of Kaesong that the landscape is similar to that around Pyongyang.However , the terrain is much impaired by the hitherto nowhere experienced large-scale and uncoordinated deforestation and the subsequently forthcoming erosion of unbelievable measure. There are thus vast mountainous declivities now completely barren and good for nothing more: no forest can gain a hold on these areas and, at most, only a dry bush or extensive shrubberies may develop. The monsoon periods further aggravate the bad situation. In spite of this,the original plant cover, the deciduous woods, survived in some fine and contiguous stands locally. Coniferous trees predominate also here in the lower-lying regions, and the southern slopes also carry sweet chestnut stands. In the higher altitudes ,forests similar to those of the Diamond Range had developed. The area was very dry at the time of our visit. The water of the brooks and streams are wholly utilized for irrigation by the villages around Kaesong: most of the streams never reach the town it self.Water and its accompanying aquatic fauna, or the great majority of the fauna at all, exist therefore only at the higher levels, where, similarly again to the situation in the Diamond Range, small rivulets or seeping waters are observable in every small lateral valley; however, the other famous waterfall of Korea, the Bagyon popo is also here. Zoologically, the territory is also a good collecting area;no largescale DDT application was observable. The fauna appeared to be undisturbed along the roads, indeed, even the aquatic fauna seemed to be richer - wherever there was water - than in the previous localities; the great individual numbers of the insect larvae were rather conspicuous. During our stay in Korea, weather was largely favourable for zoological field work, though somewhat drier than desirable.
