The Hebrew analogies now claim investigation; and as Woman is first in the affections and in memory, she claims by right upon this, as upon all occasions, the natural precedence. The Northern mother, after childbirth, is secluded for a given number of days, _varying according to the sex of the new-born infant_. By the law of MOSES, the mother's purification was to last 40 days for a male, and 80 days for a female child. _All other seclusions_ are as strict as when the wife becomes a mother. When a wife becomes a widow, and is childless, _her husband's brother marries her_,--these were essential laws of the Hebrew, and especially the latter,--that a name should not be lost in Israel. As a mother she considers it a religious duty, that the child should receive its nourishment from the breast that gave it life: and such is the feeling in the performance of this maternal duty, that she often nurses her offspring until it attains three or four years of age. From this fact an important problem is solved, viz., the apparent tardiness in the ratio increase of the Aborigines of the North:--for it is the rule in Nature's female code (and should there be an exception, it only proves the rule), that while that affection continues from the fond practice of the mother, no other shall arise to destroy that which already exists: but, as that ceases and the first-born is put away, Nature jealous of her supremacy, again bestows upon the mother a second joy, and so continues in her undeviating course. There is, also, a direct physical analogy between the Northern mothers and those of ancient Israel; if there were not, the negative might be brought against this theory: we therefore take advantage of the affirmative. The only cause of Pharaoh's _political_ action against the Hebrews was, that from the rapid ratio in which they multiplied, they would eventually rebel, and with, or without the assistance of any other nation entirely subdue Egypt. The ease of childbirth by the Hebrew mother is distinctly stated in Holy-Writ, in contrast to the dangerous sufferings of the Egyptian parent; from which fact may be gathered the cause of the gradual, but certain increase of the Israelites over the Egyptian population. The same peculiar facility of childbirth is one of the chief characteristics of the Northern female, for in the Rocky Mountains, while journeying in cavalcade, and being taken in travail, the mother will leave her companions alone, and within an hour, will remount her horse, and overtake her associates, with the new-born infant in her arms! The cause why the population of the Aborigines of the North is not in ratio with the ancient Hebrews, has already been alluded to, in reference to the mother's belief and practice of extended maternal duty and fondness.
