In Australian families it has been the universal custom to bring up only a few children in each family--usually two boys and a girl--the others being destroyed by their own parents, with no more compunction than we show in drowning superfluous puppies or kittens. The Kurnai tribe did not kill new-born infants, but simply left them behind. "The aboriginal mind does not seem to perceive the horrid idea of leaving an unfortunate baby to die miserably in a deserted camp" (Fison and Howitt, 14). The Indians of both North and South America were addicted to the practice of infanticide. Among the Arabs the custom was so inveterate that as late as our sixth century, Mohammed felt called upon, in various parts of the Koran, to discountenance it. In the words of Professor Robertson Smith (281): "Mohammed, when he took Mecca and received the homage of the women in the most advanced centre of Arabian civilization, still deemed it necessary formally to demand from them a promise not to commit child-murder." Among the wild tribes of India there are some who cling to their custom of infanticide with the tenacity of fanatics. Dalton (288-90) relates that with the Kandhs this custom was so wide-spread that in 1842 Major Macpherson reported that in many villages not a single female child could be found. The British Government rescued a number of girls and brought them up, giving them an education. Some of these were afterward given in marriage to respectable Kandh bachelors, "and it was expected that they at least would not outrage their own feeling as mothers by consenting to the destruction of their offspring. Subsequently, however, Colonel Campbell ascertained that these ladies had no female children, and, on being closely questioned, they admitted that at their husbands' bidding they had destroyed them." In the South Sea Islands "not less than two-thirds of the children were murdered by their own parents." Ellis (_P.R_., I., 196-202) knew parents who had, by their own confession, killed four, six, eight, even ten of their children, and the only reason they gave was that it was the custom of the country. "_No sense of irresolution or horror appeared to exist_ in the bosoms of those parents, who deliberately resolved on the deed before the child was born." "The murderous parents often came to their (the missionaries') houses almost before their hands were cleansed from their children's blood, and spoke of the deed with worse than brutal insensibility, or with vaunting satisfaction at the triumph of their customs over the persuasions of their teachers."
