their reach. The want of food to support this increase operates, in the end, as a positive obstacle to the further spread of population, and men are starved because the great mass of them have neglected to listen to one of nature's clearest teachings. The unchecked increase of population is in a geometrical ratio, the increase of food for their subsistence is in an arithmetical ratio. That is, while humankind would increase in proportion as 1, 2, 4, 8, 16, 32, 64, 128, 256, food would only increase as 1, 2, 3, 4, 5, 6, 7, 8, 9. The more the mouths the less the proportion of food. While the restraint to an increase of population is thus a want of food, and starvation is the successful antagonist of struggling human life, it is seldom that this obstacle operates immediately—its dealing is more often indirectly against its victims. Those who die of actual famine are few indeed compared with those who die from various forms of disease, induced by scarcity of the means of subsistence. If any of my readers doubt this, their doubts may be removed by a very short series of visits to the wretched homes of the paupers of our great cities. Suicide is the refuge mainly of those who are worn out in a bitter, and, to them, a hopeless struggle against accumulated ills. Disease, suffering, and misery are the chief causes of the prevalence of suicide in our country, and suicide is therefore one form, although comparatively minute, in which the operation of the law of population may be traced.
From dread of the pangs of poverty, men, women, and children are driven to unwholesome occupations, which destroy not only the health of the man and woman actually employed, but implant the germs of physical disease in their offspring. A starving woman seeking food mixes white lead with oil and turpentine for a paltry pittance, which provides bare existence for her and those who share it; in a few weeks, she is so diseased she can work no longer, and the hospital and grave in turn receive her. Men and women are driven to procure bread by work in lead mines; they rapidly dig their own graves, and not alone themselves,
