In all places of the civilized world, and in all classes, the struggle for existence is now more keen than ever it has been during the history. Everywhere men, and women, and children are living at a pressure positively frightful to contemplate. Amid the swarming bustle of our smoke-smothered towns, surrounded by their zone of poisoned trees, amid the whirling roar of machinery, the scorching blast of furnaces, and in the tallow-lighted blackness of our mines—everywhere, men, and women, and children are struggling for life.

Or if we look to our universities and schools, to our professional men and men of business, we see this same fierce battle rage—ruined health and shattered hopes, tearful lives and early deaths being everywhere the bitter lot of millions who toil, and strive, and love, and bleed their young hearts' blood in sorrow.
