Nor are these advantages confined to those departments of nature where her mightiest forces are brought into requisition. In accomplishing whatever requires delicacy and precision, nature is as much more perfect than man as she is more powerful in whatever requires strength. Whether in great or in small operations, all the improvements in the mechanical and the useful arts come as directly from intelligence as a bird comes out of a shell, or the beautiful colors of a flower out of sunshine. The slave worker is forever prying at the short end of Nature’s lever, and using the back instead of the edge of her finest instruments. Sir, the most abundant proof exists, derived from all departments of human industry, that uneducated labor is comparatively unprofitable labor. I have before me the statements of a number of the most intelligent gentlemen of Massachusetts, affirming this fact as the result of an experience extending over many years. In Massachusetts we have no native-born child wholly without school instruction; but the degrees of attainment, of mental development, are various. Half a dozen years ago, the Secretary of the Massachusetts Board of Education obtained statements from large numbers of our master manufacturers, authenticated from the books of their respective establishments, and covering a series of years, the result of which was, that increased wages were found in connection with increased intelligence, just as certainly as increased heat raises the mercury in the thermometer. Foreigners, and those coming from other states, who made their marks when they receipted their bills, earned the least; those who had a moderate or limited education occupied a middle ground on the pay-roll; while the intelligent young women who worked in the mills in winter, and taught schools in summer, crowned the list. The larger capital, in the form of intelligence, yielded the larger interest in the form of wages. This inquiry was not confined to manufactures, but was extended to other departments of business, where the results of labor could be made the subject of exact measurement. This is universally so. The mechanic sees it, when he compares the work of a stupid with that of an awakened mind. The traveller sees it, when he passes from an educated into an uneducated nation. Sir, I have seen countries in Europe, lying side by side, where, without compass or chart, without bound or landmark, I could run the line of demarcation between the two, by the broad, legible characters which ignorance has written on roads, fields, houses, and the persons of men, women, and children, on one side, and which knowledge has inscribed on the other.
