A young woman of twenty reacts with intuitive promptitude and security in all the usual circumstances in which she may be placed. Her likes and dislikes are formed; her opinions, to a great extent, the same that they will be through life. Her character is, in fact, finished in its essentials. How inferior to her is a boy of twenty in all these respects! His character is still gelatinous, uncertain what shape to assume, "trying it on" in every direction. Feeling his power, yet ignorant of the manner in which he shall express it, he is, when compared to his sister, a being of no definite contour.
