We are living to-day in a period of unrest and change, such as the world has never known before. A new social consciousness has awakened throughout the civilized world, a feeling that for those who are to come after us, life should be happier and better than it is. Humanity is advancing toward its ideals by leaps and bounds, where once it slowly crept. Every social problem, from the prevention of cruelty, the suppression of vice, the rescue of the submerged, to the abolition of poverty itself, is to-day more in the thought of humanity than ever before in the history of the world. We are but just beginning to learn our duties to human beings of other races; may we not be assured that the more sensitive conscience of the future will define with authority, our duties to the humbler sharers of this mysterious gift of life? Already, Science has told us, that far in the past, we had the same origin; and surely, when some higher ideal than utility to ourselves, shall dominate human conduct, there will be a new conception of JUSTICE toward every sentient being. It may mean extinction of species; but it will notmean their torment. You and I cannot hope for life long enough to see the realization of that dream. And yet, sometimes I have wondered whether it be so far distant as I have feared. But a little while ago, who of us could have imagined that in our day, the Government of the United States would listen to the cries of little birds, starving on their nests in the swamps of Florida, and prohibit the importation of the egret plumes? How much of hopefulness for the final triumph of th eprinciples of humaneness lies in the passage of such a law! I fancy that one day, all noxious animals, and especially those which prery upon other creatures, will largely, if not entirely, disappear. It is calculated that ever grown lion in South Africa kills for food, every year, between 200 and 300 harmless animals, and each one of which is as much entitled as the lion to the happiness of existence. In great museums to-day, we see the remains of creatures, like the sabre-toothed tiger, that lived probably, over a million years ago. In a century or two, hence, the skeletons of the panther, the tiger, the leopard and the lion, will be found in the same halls of science, with those of other extinct species, that could exist only at the expense of others' lives.
