Youthful Flirtations.--Flirting is not confined to young men and women. The contagion extends to little boys and girls, whose heads ought to be as empty of all thoughts of sexual relations as the vacuum of an air-pump of air. The intimate association of young boys and girls in our common schools, and, indeed, in the majority of educational institutions, gives abundant opportunity for the fostering of this kind of a spirit, so prejudicial to healthful mental and moral development. Every educator who is alive to the objects and interests of his profession knows too well the baneful influence of these premature and pernicious tendencies. Many times has the teacher watched with a sad heart the withering of all his hopes for the intellectual progress of a naturally gifted scholar by this blighting influence. The most dangerous period for boys and girls exposed to temptations of this sort is that just following puberty, or between the ages of twelve and eighteen or twenty. This period, a prominent educator in one of our Western States once denominated, not inappropriately, "the agonizing period of human puppyhood." If this critical period is once safely passed, the individual is comparatively safe; but how many fail to pass through the ordeal unseared! The most painful phase of this subject is the tacit--even, in many cases, active--encouragement which too many parents give their children in this very direction, seemingly in utter ignorance of the enormity of the evil which they are winking at or fostering. Parents need enlightenment on this subject, and need to be aroused to the fact that it is one of the most momentous questions that can arise in the rearing and training of children. Polygamy.--One hundred years ago the discussion of the public propriety or impropriety of a plurality of wives would have been impossible. Polygamy had not obtained a foothold as an institution in any civilized land. Being well known as not uncommon among certain heathenish and barbarous tribes, it was looked upon as a heathenish and debasing institution, the outgrowth of ignorance and gross sensuality, and a relic of a sensual age. Now, this is no longer true. Even in this, the most enlightened of all lands, where there are most ample facilities for culture, for moral and mental development, polygamy holds up its hideous head in defiance of all the laws of God and man. It is true that the perpetrators of this foul crime against humanity and Heaven have been driven by the indignation of outraged decency to seek a lurking place in the far-off wilderness of the Western territories; yet the foul odors from this festering sore are daily becoming more and more putrescent, and in spite of the distance, are contaminating the already not overstrict morals of the nation.
