The happiness of some lives is distributed pretty evenly over the whole stretch from the cradle to the grave, while that of others comes all at once, glorifying some particular epoch and leaving the rest in shadow. During one, five, or ten blithe years, as the case may be, all the springs of life send up sweet waters; joy is in the very air we breathe; happiness seems our native element. During this period we know what is the zest of living, as compared with the mere endurance of existence, which is, perhaps, the most we have attained to before or since. With men this culminating epoch comes often in manhood, or even at maturity, especially with men of arduous and successful careers. But with women it comes most frequently perhaps in girlhood and young womanhood. Particularly is this wont to be the fact with women who do not marry, and with whom, as the years glide on, life becomes lonelier and its interests fewer.
