But in 1807 Manual Lisa ascended the Missouri river and built a post at the mouth of the Big Horn and, in 1809, formed the Missouri Fur company. A rival organization headed by William H. Ashley in 1822 founded the Rocky Mountain Fur company; the American Fur company, of which John Jacob Astor was the principal figure established an office in St. Louis in 1822 and soon became the dominant factor in the fur trade. Astor retired in 1834 and the western department of the company was sold to Pratte, Chouteau and company. This organization continued to control most of the western fur trade until 1860. St. Louis was also the outfitting place for much of the trade with the North Mexican provinces.
Company, the parent of the Missouri Pacific, was organized in 1850; the line was begun in 1851, and the first 4o m. were opened to Franklin, Mo., two years later. In 1855 it reached Jefferson city, and Sedalia in 1861. A south-western branch of the Missouri Pacific was opened to Rolla in 1861. The St. Louis and Iron Mountain railway, incorporated in 1851, was opened from St.
Louis to Pilot Knob, Mo., in 1858. The St. Louis, Kansas City and Northern railway was completed as far as Macon, Mo., in 1859. Thus before the Civil War St. Louis became the terminal for four western railroads. The Ohio and Mississippi railroad, to Cincinnati, was completed in 1857 ; it connected with the Balti more and Ohio railroad, thus giving St. Louis rail access to the Atlantic coast.
By 1860 the city extended for about 6-i m. along the river front and reached westward between 3 and 4 miles. Most of the houses were built of brick, as were many of the sidewalks. Soft coal was used as fuel, frequently creating a pall of smoke. Missouri was a slave State, but only 1,50o slaves were owned in St. Louis and most of these were in domestic service. The Germans and the newcomers from the North were abolitionists. Many of the business men, regardless of their views on the slavery question, were opposed to secession. They feared that a break in the Union would be injurious to business, and felt that it was vital to St. Louis to have the Mississippi river under the control of the United States.
The next step of the Unionists was to prevent the St. Louis arsenal from falling into the hands of the secessionists. Capt.
Nathaniel Lyon, with the assistance of the "Wide Awakes," who had been transformed into military companies known as "home guards," succeeded in protecting the arsenal and in shipping most of its guns to Illinois. The governor then authorized the assembly of militia near St. Louis. A camp, named after the governor, was laid out on the western outskirt of the city. Lyon and Blair believed that the purpose of the establishment of Camp Jackson was the seizure of the city. On May Io, 1861, Lyon sent three columns of home guards to capture the camp. The force was overwhelming and Frost, the commander, surrendered with out a struggle. An unfortunate outbreak of violence occurred while the prisoners were under guard and about 25 people, several of them civilians, were killed or wounded. For 48 hours the citizens were in a state of panic, but when no other acts of violence occurred, the excitement subsided, and those who had fled returned to their homes.
