I have failed to perceive any other. Two things, however, are clear, as forming the basis on which his theory stands:
1. That "female infanticide" was the general practice among the "primary hordes"—in other words, that they killed many more female children than male.
2. That exogamous tribes existed under "circumstances in which men could only get wives by capturing them"—in other words, that these tribes could not marry anywhere within their own boundaries, and were consequently compelled to capture their wives, there being no possibility of friendly intermarriage with other tribes.
Let us now test this basis, and see if it be secure: It is well known that infanticide is a very common practice among savage and barbaric tribes, and the opinion seems to prevail that "female infanticide"—the killing of female children rather than male—is the general rule. This opinion is undoubtedly correct as to many tribes; but I venture to suggest that it needs reconsideration as far as the lower savages are concerned, and it is with them that the theory now under consideration has to do. I think it will be found that the practice is far less common with them than it is among the tribes who are more advanced, and for this opinion I will now endeavor to show cause.
Savages are perfectly logical people in their own way, and do not act without a motive, which, to their minds at least, is a sufficient one. So thoroughly have I been convinced of this by my fifteen years' residence among them, and close observation of their ways, that I do not hesitate to affirm that, whenever their acts appear capricious to us, we may be quite sure we do not understand their motives. The savage has no hesitation in killing his infant children, whether male or female, if they be in his way; but he does not kill any one of them for the mere sake of killing, and he certainly would not kill his daughters rather than his sons without a sufficient motive. Is such a motive to be found among the lower savages?
The reasons usually given for female infanticide are thus stated by Sir John Lubbock and Mr. McLennan:
"Female children became a source of weakness in various ways. They ate and did not hunt. They weakened their mothers when young, and when grown up were a temptation to surrounding tribes."[1]
To the same effect Mr. McLennan observes: "To tribes surrounded by enemies and unaided by art, contending with the difficulties of subsistence, sons were a source of strength, both for defense and in quest of food, daughters a source of weakness."[2]
The motive here advanced is, that females are an incumbrance to savages, and for this four reasons are given:
1. "They weaken their mothers when young."
