I do not know that I can better illustrate the great truth that only part of the world is adapted to the production of great men and women than by calling your attention to the difference between vegetation in valleys and upon mountains. In the valley you find the oak and elm tossing their branches defiantly to the storm, and as you advance up the mountain side the hemlock, the pine, the birch, the spruce, the fir, and finally you come to little dwarfed trees, that look like other trees seen through a telescope reversed--every limb twisted as though in pain--getting a scanty subsistence from the miserly crevices of the rocks. You go on and on, until at last the highest crag is freckled with a kind of moss, and vegetation ends. You might as well try to raise oaks and elms where the mosses grow, as to raise great men and great women where their surroundings are unfavorable. You must have the proper climate and soil. A few years ago we were talking about the annexation of Santo Domingo to this country. I was in Washington at the time. I was opposed to it I was told that it was a most delicious climate; that the soil produced everything. But I said: "We do not want it; it is not the right kind of country in which to raise American citizens. Such a climate would debauch us. You might go there with five thousand Congregational preachers, five thousand ruling elders, five thousand professors in colleges, five thousand of the solid men of Boston and their wives; settle them all in Santo Domingo, and you will see the second generation riding upon a mule, bareback, no shoes, a grapevine bridle, hair sticking out at the top of their sombreros, with a rooster under each arm, going to a cock fight on Sunday." Such is the influence of climate. Science, however, is gradually widening the area within which men of genius can be produced. We are conquering the north with houses, clothing, food and fuel. We are in many ways overcoming the heat of the south. If we attend to this world instead of another, we may in time cover the land with men and women of genius.
