The monopolistic venture failed. Many of the colonists whom the company entered died or ran away; millions of pounds had been spent, there was no return, and there was little tangible to show for it all--a few thousand white settlers, many of whom, in a phrase current to-day in the States, were "undesirable citizens," living in palisaded cabins. So the little settlement became a crown colony again and came back to the king, but not to him in whose name it had been originally taken, for that king was dead. Louis XIV's name, kept in "Louisiana," claims now but a fragment of that vast territory which might have been his forever. The little outcast colony was laid on the steps of Versailles again, and was again subject to "paternalistic nursing," because of or in despite of which it began at last to show signs of growth. It was at the cost of a half-century of time, of eight or more millions of livres to the king, Crozat and the company, of millions upon millions more to those who bought the worthless stock of the Mississippi Company, and of ignominy and shame, that La Salle's dream began to have realization, while on the Atlantic seaboard the English colonies were growing luxuriantly in comparative neglect. Meanwhile French explorers were traversing this mighty interior valley with all the spirit of Cartier, Joliet, Champlain, and La Salle. Pierre Charles le Sueur had ascended the Mississippi far toward its source in search of copper and lead. Bernard de la Harpe and Louis Juchereau, the Sieur de St. Denis, explored the Red River and penetrated as far as the Spanish settlement of St. Jean Baptiste on the Rio Grande. Each might have a volume. The turbid Missouri even (which Marquette and Joliet first saw heading great trees down into the Mississippi) was not passed by as impervious to the hardihood of undaunted, amphibious geographers such as La Harpe and Du Tisne. Two brothers, Pierre and Paul Mallet, penetrated to the old Spanish settlement at Santa Fé and may have been the first of Frenchmen to see the farther boundary of the valley, the Rocky Mountains. Whether they did or not, it is certain that far to the northwest two other brothers did reach that mighty range and "discovered that part of it to which the name Rocky Mountains properly belongs."
