In the evening Aban Tingan, the brother of the great Kenyah chief Tama Bulan, and several of his countrymen turned up at the Residency, and we had a great drinking evening in true Kenyah style, chanting speeches while presenting a drink, moving the glass backwards and forwards till the time comes for the actual drinking. Whilst the glass is being drained at a gulp all shout in a peculiar manner. It was really a most effective performance, and might with advantage be introduced at home.

I felt it to be an appropriate, though quite an unarranged, welcome to Marudi. Ray gave a phonographic performance, and not very late in the evening Aban Tingan arrived at a well-known garrulous stage, and, later on, he did not realise that we should be glad if he departed.

CHAPTER XX
THE COUNTRY AND PEOPLE OF BORNEO

(a) THE GEOGRAPHICAL AND GEOLOGICAL FEATURES OF BORNEO

The centre of Borneo does not appear to be occupied by one great central continuous range of old folded mountains, but by numerous more or less isolated peaks and ridges which rise in linear series from a medley of hills. These high mountain islands not only occur in the higher hill-land, but many rise up from the low hills that merge into great coastal plains.

The central mountains radiate from Gunong Tebang, which lies in lat. 3° N. and long. 115° 3′ 25″. From this central watershed an axial ridge proceeds north-eastwards, and culminates in Kina Balu, 4,175 m. (13,698 feet), the highest mountain in the island. A south-east ridge ends at Cape Kaniongan. An irregular southerly chain terminates in the Island Pulo Laut and in Cape Salatan. A broad south-westerly series of mountains stretches toward Cape Sambar; a more westerly branch of the latter system curves round to the north and terminates at Cape Datu. The latter watershed constitutes the boundary between Sarawak and Dutch Borneo.

On account of the peculiar configuration of mountain masses and divides, Borneo contains a number of extensive and distinct river basins, which radiate from the eccentric mountain centre.

The mountains proper are surrounded by hill-land, which gradually becomes lower towards the plains. Schwaner states that “these hills do not form ranges inclosing plains and valleys, nor are they very defined as regards height and form. They may be described as an aggregate of rounded or extended masses, often with very steep sides. Their usual height seldom exceeds 200 to 300 feet; only in the neighbourhood of the divide do they become higher and give the country a more mountainous character.” The hill-land also sends spurs into the low-lying plains, which appear as outliers.
