When the State of Louisiana was received into the Union in 1812, there was left out a large proportion of the original purchase from Napoleon. As yet this region was unpeopled. It lay silent and unprofitable--a vast reserve prepared for the wants of unborn generations. It was traversed by the Missouri river. The great Mississippi was its boundary on the east. It possessed, in all, a navigable river-line of two thousand miles. Enormous mineral wealth was treasured up to enrich the world for centuries to come. There were coal-fields greater than those of all Europe. There was iron piled up in mountains, one of which contained two hundred million tons of ore. There was profusion of copper, of zinc, of lead. There were boundless forests. There was a soil unsurpassed in fertility. The climate was kindly and genial, marred by neither the stern winters of the North nor the fierce heats of the South. The scenery was often of rare beauty and grandeur. This was the Territory of Missouri. Gradually settlers from the neighbouring States dropped in. Slave-holders came, bringing their chattels with them. They were first in the field, and they took secure possession. The free emigrant turned aside, and the slave-power reigned supreme in Missouri. The wealth and beauty of this glorious land were wedded to the most gigantic system of evil which ever established itself upon the earth. By the year 1818 there were sixty thousand persons residing in Missouri. The time had come for the admission of this Territory into the Union as a State. It was the first great contest between the Free and the Slave States. The cotton-gin, the acquisition of Louisiana, the teaching of Calhoun, had done their work. The slave-owners were now a great political power--resolute, unscrupulous, intolerant of opposition. The next half century of American history takes its tone very much from their fierce and restless energy. Their policy never wavered. To gain predominance for slavery, with room for its indefinite expansion, these were their aims. American history is filled with their violence on to a certain April morning in 1865, when the slave-power and all its lawless pretensions lay crushed among the ruins of Richmond.
