In the first (in which such tribes as the Dyaks have remained) they were semi-barbarous.
The natives in language and customs present affinities with some Polynesians, and have been held to be a survival of the eastward immigration of people of Caucasian stock which took place before those which established the " pre-Malay "peoples (such as the Dyaks and Battas) in the Malay Archipelago.
Similar constructions have been described by travellers, among the Dyaks of Borneo, in Celebes, in the Caroline Islands, on the Gold Coast of Africa, and in other places.
Here were Hausas from the Niger and the Gold Coast, coloured men from the West India regiments, zaptiehs from Cyprus, Chinamen from Hong Kong, and Dyaks - now civilized into military police - from British North Borneo.
They were followed by an immigration of Mongol-Caucasic peoples with a preponderance of Caucasic blood-the Indonesians of some, the pre-Malays of other writers-who are to-day represented in the archipelago by such peoples as the Dyaks of Borneo and the Battas of Sumatra.
