This metallic product for the year, it is estimated, was turned by manufacturing it into materials having a market value of fifteen thousand millions of dollars. If we add that of agriculture, the metallic products, and manufacturing, together, we have a total valuation for the year of twenty-four thousand millions of dollars. The fertility of our natural resources is here shown by their rapid rate of development. But this, while contributing so largely to our present national wealth, is not an unmixed good. We should always bear in mind that the more we take out of the earth, and the more we strip our forests of timber, the less we have remaining. In forestry, however, we are now preparing for the future by replanting, but we cannot replant minerals.🏁
