Peoples generally recognised as closely akin to the KARENS are the CHINS (who are also known as Khyens) (14) of the basin of the Chindwin, the large western tributary of the Irrawadi; and the KAKHYENS (also called KACHINGS and SINGPHO), who occupy the hills east of Bhamo and the basin of the river Tapang in the borderlands of Burma and Yunnan (7). The Nagas of Manipur and of the Naga Hills of Assam also seem to belong to the same group of peoples, though less closely akin to the Karens than the Chins and the Kakhyens.

It seems highly probable that all these, together with the Kayans, are surviving branches of a people which occupied a large area of south-eastern Asia, more especially the basin of the Irrawadi, for a considerable period before the first of the successive invasions which have given rise to the existing Burmese and Shan nations. The physical characters of all of them are consistent with the view taken above, namely, that they represent the original Indonesian population of which the Klemantans of Borneo are the pure type, modified by later infusions of Mongol blood. In all these occur individuals who are described as being of almost purely Caucasic type and very light in colour.

Three principal tribes of Karens are distinguished, the Sgan, Pwo, and Bwe. Of these the Bwe are also known as the Hill-Karens and seem to have preserved their own culture more completely than the others, though the Sgan are said to be the purest in blood, the lightest in colour, and more distinctive in type than any other of the tribes of south-eastern Asia (4). Of the Hill-Karens, Mason said, "Some would be pronounced European. Indeed, if not exposed to the sun, some of them would be as fair, I think, as many of the inhabitants of northern Europe." Yet the commoner type of Karen is said to show distinctly Mongoloid facial characters. Of those Karens who have been least affected by their more cultured neighbours, we are told that they live in small communities, each of which is governed by a patriarch who is at once high priest and judge, and who punishes chiefly by the infliction of fines. He raises no regular tax, but receives contributions in kind towards the expenses of entertainment (3). Several communities join together, sometimes under a leading chief, in order to meet a common foe (3). They build long houses in which a whole community of as many as 400 persons dwell together (4). These houses are described as of Himalayic type. "It (the house) is made by sinking posts of large size firmly in the ground and inserting beams or joists through the posts eight feet from the ground, and on these laying the floor with slats of bamboo." The walls and partitions are mats of woven bamboo, and the roof is thatched with palm leaves (4). This very incomplete description leaves it open to suppose that the Karen house is very similar to that built by the Kayans when for any reason the latter build in hasty and temporary fashion. But the still more scanty description of another writer (3) implies that the arrangement of the interior of the house is unlike that characteristic of the Kayans. They frequently migrate to new sites.

The Karens cultivate PADI and prepare the jungle land for cultivation by burning down the forest. They prepare from rice a spirit to which they are much addicted. The hill tribes are truculent warriors and head-hunters. Captives are made slaves. They use and make spears and axes, and a cross-bow[199] with poisoned arrows. They rear pigs and poultry, and train dogs to the chase. The men eradicate their beards. They wear many small rings on the forearms and legs. The lobes of the ear are perforated and often enormously distended (3).

They address prayers and supplications for protection and prosperity to a Supreme Being whom they address as "Lord of the heavens and earth" (5). They believe also in a multitude of nature spirits, most of whom are harmful. The fear of them occasions many ceremonial acts. The taking of heads is said to be a means of propitiating these spirits (3). They believe that during sickness the soul departs from the body; and the medicine-man attempts to arrest it and to bring it back to the body of the patient. In this and other rites the blood of fowls (which they are said to venerate) (2) is smeared on the participants. Divination by means of the bones of fowls and the viscera, especially the liver of the pig, is in common use (5). The souls of the dead go to a place in which they live much as in this world. It is called ABU LAGAN[200] (3). In this abode of shades everything is upside down and all directions are inverted (5). There are no rewards and punishments after death (3). Parents take the names of father and mother of So-and-so — the name of their first child. The knife with which the navel cord is cut at birth is carefully preserved (5). Finally, the Karens are said to be distinguished by a lack of humour, a trait which is well marked also in the Kayans.

In respect of all the characters and culture elements mentioned above, the Karens resemble the Kayans very closely. Against these we have to set off a few customs mentioned by our authorities in which they differ from the Kayans.

The Karens eat everything except members of the cat tribe. They bury the bodies of the dead after they have lain in state some three or four days; and they hold an annual feast for the dead at the August new moon. They ascribe two souls to man, one of a kind which is possessed also by animals, tools, weapons, the rice, and one which is the responsible soul peculiar to man.[201]

The bride is taken to the house of the bridegroom's father. Only one tribe, namely, the Red Karens, practises tatu, and among them a figure which seems to represent the rising sun is tatued on the back of the men only (5). They weave a coarse cloth.

These differences are not very great, and their significance is diminished by the following considerations. The Kayans may have acquired their aversion to killing the dog through contact with Malays. They bury the dead in the ground in the case of poor persons or those dead of epidemic disease. And they have a tradition that they formerly practised the weaving of cloth. They may also have acquired the art of making and using the solid wooden blow-pipe from Malays; and this would account for their having given up the use of the bow and arrow as a serious weapon. On the other hand, the inferior houses of the Karens, the lack of restrictions among them upon animal foods, their earth burial — all these may well be due to decay of custom among an oppressed people; and the fact that they seem to make but little use of boats may well be due to their having been driven away from the main rivers and pushed into the hills. We have little doubt that many more points of resemblance would be discoverable, if we had any full account of the Karens as they were before their culture was largely affected by contact with Burmese and Shans and by the influence of the missionaries who have taught so successfully among them for more than sixty years.

Among the elements of Kayan culture which are lacking or but feebly represented among the Karens, some are reported among the tribes most nearly allied to the Karens, and others among other peoples of the same area.
