It is now but little more than seventy years since the Elector of Hesse sold large numbers of his poor subjects to the government of England to aid it in establishing unlimited control over the people of this country. About the same period, Frederick of Prussia had his emissaries everywhere employed in seizing men of proper size for his grenadier regiments--and so hot was the pursuit, that it was dangerous for a man of any nation, or however free, if of six feet high, to place himself within their reach. The people were slaves, badly fed, badly clothed, and badly lodged, and their rulers were tyrants. The language of the higher classes was French, German being then regarded as coarse and vulgar, fit only for the serf. German literature was then only struggling into existence. Of the mechanic arts, little was known, and the people were almost exclusively agricultural, while the machinery used in agriculture was of the rudest kind. Commerce at home was very small, and abroad it was limited to the export of the rude products of the field, to be exchanged for the luxuries of London or Paris required for the use of the higher orders of society. Thirty years later, the slave trade furnished cargoes to many, if not most, of the vessels that traded between this country and Germany. Men, women, and children were brought out and sold for terms of years, at the close of which they became free, and many of the, most respectable people in the Middle States are descended from "indented" German servants. The last half century has, however, been marked by the adoption of measures tending to the complete establishment of the mechanic arts throughout Germany, and to the growth of places for the performance of local exchanges. The change commenced during the period of the continental system; but, at the close of the war, the manufacturing establishments of the country were, to a great extent, swept away, and the raw material of cloth was again compelled to travel to a distance in search of the spindle and the loom, the export of which from England, as well as of colliers and artisans, was, as the reader has seen, prohibited. But very few years, however, elapsed before it became evident that the people were becoming poorer, and the land becoming exhausted, and then it was that were commenced the smaller Unions for the purpose of bringing the loom to take its natural place by the side of the plough and the harrow. Step by step they grew in size and strength, until, in 1835, only twenty years after the battle of Waterloo, was formed the _Zoll-Verein_, or great German Union, under which the internal commerce was rendered almost entirely free, while the external one was subjected to certain restraints, having for their object to cause the artisan to come and place himself where food and wool were cheap, in accordance with the doctrines of Adam Smith.
