They produce fire both by collision and by attrition; the former by striking two stones one against another, on one of which a good deal of brimstone is first rubbed. The latter method is with two pieces of wood; one of which is a stick of about eighteen inches in length, and the other a flat piece. The pointed end of the slick they press upon the other, whirling it nimbly round as a drill; thus producing fire in a few minutes. This method is common in many parts of the world. It is practised by the Kamtschadales, by these people, by the Greenlanders, by the Brazilians, by the Otaheiteans, by the New Hollanders, and probably by many other nations. Yet some learned and ingenious men have founded an argument on this custom to prove, that this and that nation are of the same extraction. But accidental agreements, in a few particular instances, will not authorise such a conclusion; nor will a disagreement, either in manners or customs, between two different nations, of course, prove that they are of different extraction. I could support this opinion by many instances besides the one just mentioned.18
