Committed to the enterprise, the firm proceeded to organize the Central Overland California and Pike's Peak Express Company, obtaining a charter under the State laws of Kansas. [Illustration: Why one rider was late.] The company had an established route with the necessary stations between St. Joseph and Salt Lake City. Chorpenning's line west of Salt Lake City had few or no stations, and these had to be built; also some changes in the route were considered advisable. The service comprised sixty agile young men as riders, one hundred additional station-keepers, and four hundred and twenty strong, wiry horses. So well did those in charge understand their business that only sixty days were required to make all necessary arrangements for the start. April 3, 1860, was the date agreed upon, and on that day the first pony express left St. Joseph and San Francisco. In March, 1860, the following advertisement had appeared in the _Missouri Republican_ of St. Louis and in other papers: To San Francisco in 8 days by the C. O. C. & P. P. Ex. Co. The first courier of the Pony Express will leave the Missouri River on Tuesday, April 3rd, at---- P. M., and will run regularly weekly hereafter, carrying a letter mail only. The point on the Mo. River will be in telegraphic connection with the east and will be announced in due time. Telegraphic messages from all parts of the United States and Canada in connection with the point of departure will be received up to 5:00 P. M. of the day of leaving and transmitted over the Placerville & St. Jo to San Francisco and intermediate points by the connecting express in 8 days. The letter mail will be delivered in San Francisco in 10 days from the departure of the express. The express passes through Forts Kearney, Laramie, Bridger, Great Salt Lake City, Camp Floyd, Carson City, The Washoe Silver Mines, Placerville and Sacramento, and letters for Oregon, Washington Territory, British Columbia, the Pacific Mexican ports, Russian possessions, Sandwich Islands, China, Japan and India will be mailed in San Francisco. Both Sacramento and San Francisco were afire with enthusiasm, and elaborate plans were set on foot to welcome the first express. At the former point the whole city turned out with bells, guns, bands, etc., to greet it. Making only a brief stop to deliver the mail for that point, the express was hurried abroad the swift steamer _Antelope_, and sent forward to San Francisco. Here its prospective arrival had been announced by the papers, and also from the stages of the theaters, so that an immense as well as enthusiastic crowd awaited its arrival at midnight. The California Band paraded; the fire-bells were rung, bringing out the fire companies, who, finding no fire, remained to join in the jollity and to swell the procession which escorted the express from the dock to the office of the Alta Telegraph, its Western terminus.
