Hospitality, as will be seen in a subsequent chapter, is a stringent duty in the savage world. Custom requires that the host should entertain and protect a stranger who comes as his guest, and by killing him the host would perpetrate an outrage hardly possible. Moreover, even in the case of intertribal relations, we must not conclude that what is allowed in war is also allowed in times of peace. The prohibition of homicide may extend beyond the tribal border, to {334} members of different tribes who for some reason or other are on friendly terms with each other.[47] We must not suppose that a tribe of savages generally either lives in a state of complete isolation, or is always at odds with its neighbours. In Australia, for instance, one tribe of natives, as a rule, entertains amicable relations with one, two, or more other tribes.[48] Among the Central Australian natives, say Messrs. Spencer and Gillen, "there is no such thing as one tribe being in a constant state of enmity with another"; on the contrary, where two tribes come into contact with one another on the border land of their respective territories, friendly feelings are maintained between the members of the two.[49] Some uncivilised peoples are even said to have no wars. The Veddahs of Ceylon never make war upon each other.[50] According to the reports of the oldest inhabitants of Umnak and Unalaska, the people there had never been engaged in war either among themselves or with their neighbours, except once with the natives of Alaska.[51] To the Greenlanders described by Dr. Nansen war is "incomprehensible and repulsive, a thing for which their language has no word."[52] [Footnote 47: See, _e.g._, Scott Robertson, _op. cit._ p. 194 (Káfirs of the Hindu-Kush).] [Footnote 48: Curr, _The Australian Race_, i. 62 _sq._] [Footnote 49: Spencer and Gillen, _Native Tribes of Central Australia_, p. 32.] [Footnote 50: Sarasin, _op. cit._ iii. 488.] [Footnote 51: Coxe, _op. cit._ p. 244.] [Footnote 52: Nansen, _Eskimo Life_, p. 162.]
