poverty, squalor, wretchedness, disease, ignorance, misery, and crime. Low rate of wages, and food dear, here you have two certain indices of relative over-population. Wages depending on the demand for and supply of laborers, wherever wages are low it is a certain sign that there are too many candidates for employment in that phase of the labor market. The increased cost of production of food, and its consequent higher price, also mark that the cultivation has been forced, by the numbers of the people to descend to less productive soils. Poverty is the test and result of over-population. It is not against some possible increase of their numbers, which may produce possibly greater affliction, that the working men are entreated to agitate. It is against the existing evils which afflict their ranks, evils alleged by sound students of political economy to have already resulted from inattention to the population question, that the energies of the people are sought to be directed, The operation of the law of population has been for centuries entirely ignored by those who have felt its adverse influence most severely. It is only during the last thirty years that any of the working classes have turned their attention to the question; and only during the last few years that it has to any extent been discussed among them. Yet all the prayers that labor ever uttered since the first breath of human life, have not availed so much for human happiness as will the earnest examination by one generation of this, the greatest of all social questions, the root of all political problems, the foundation of all civil progress. Poor, man must be wretched. Poor, he must be ignorant. Poor, he must be criminal; and poor he must be till the cause of poverty has been ascertained by the poor man himself and its cure planned by the poor man's brain, and effected by the poor man's hand. Outside his own rank none can save the poor. Others may show him the abyss, but he must avoid its dangerous brink himself. Others may point out to him the chasm, but he must build his own bridge over. Labor's prayer must be to labor's head for help from labor's hand to strike the blow that severs labor's chain, and terminates the too long era of labor's suffering.
