This custom has been cited to show that the Australian women attach no importance to the lives of their children, and that, consequently, they would offer no resistance to the massacre of the new-born Mulattoes. A race of beings, where the females do not love their young, would scarcely be a human race. The custom of preserving only one twin, and to sacrifice the other on the day of its birth, seems improbable and inexplicable; but taking into consideration the famishing condition of the Australians, the uncertainty and the insufficiency of their alimentation, the absolute want of social organisation, and the material difficulty attending the bringing up of only one child, it may be imagined that the mother, incapable, perhaps, of suckling one baby, resigns herself to sacrificing one child to save the other. There is, therefore, no absolute parallel between the custom in regard to twins and that of the pretended massacre of cross-breeds. If it be still supposed that the natives of the environs of Sydney, perverted by their intercourse with convicts, and exasperated by their violence, have adopted this revolting habit, we should even then only admit that such a degradation is merely local in its application. Certain abominations spread from place to place, and are transmitted from people to people; but a usage so contrary to natural instinct, does not arise simultaneously, and under the same form in different parts of a country. The Australians, however, of Sydney, have no means of transmitting their customs either to the natives of Tasmania, or of Port Essington in North Australia. Dr. Waitz supposes that even seven hundred miles from Sydney the natives sacrifice all young Mulattoes. This supposition is rather hazardous, specially as the traveller whom he quotes merely says that these Mulattoes do not appear to be capable of development.[72] We conclude from this perhaps too lengthy discussion, that the murder of the Australian Mulattoes is a vulgar tale. Admitting that such murders occur occasionally, or even that they are frequent, there should even then be many Mulattoes in Australia provided the intermixture be very prolific. We can in the above strange explanation only find a confirmation, and a very strong one too, of the fact we have established, namely, that the cross-breeds are rare in Australia. If this fact had not been perfectly evident, there would not have been any occasion to explain it, and Mr. Cunningham, who has made such strenuous efforts to reinstate the natives, would not have charged them with such a terrible accusation.
