Previous to 1863 there was no regular line of transportation through Bannock county, the mails being carried by pony express, which made the postage on letters cost from fifty cents to one dollar each, and the few people whose business called them across southern Idaho traveled singly or in groups, in the saddle, or by wagon, as suited their convenience and opportunity. But, however they traveled, they all followed the line of the old Oregon trail. In 1863, Oliver and Conover stocked a road from Virginia City, Montana, to Salt Lake City, the impetus given to transportation in these parts by the development of the mines in Montana promising to make such a venture successful. The trail through Bannock county followed closely the present tracks of the Oregon Short Line running north from Fort Hall along the Montana division. The stations were from twelve to fifteen miles apart, there having been one at Fort Hall, another near the Lavatta ranch, another at Pocatello creek and a fourth just west of McCammon, formerly called Harkness. The freighting season opened in April and lasted until November. The bottom lands to the west of Pocatello were a favorite wintering resort for the freighters because of the facilities they offered in the way of protection, water and food. The freight wagons were drawn by either mules or oxen, and so slow was their progress that they made only from three to five trips a season. The more costly and perishable merchandise, such as drugs and chemicals, was usually carried on the passenger stages. A mule train was made up of from eight to twelve animals attached to two or three wagons; an ox train of about fourteen animals. These cumbrous outfits traveled about twelve miles a day. The passenger stages, however, traveled about one hundred miles in twenty-four hours. They were drawn by from four to six horses, who were changed every twelve or fifteen miles, while the drivers changed every fifty miles. They were usually accompanied by a messenger, who was a kind of guard and rode beside the driver. Most of the stages were of the thorough-braced type, the bodies resting upon leather straps instead of springs, which gave them an easy, swinging motion. They were usually fitted with three seats and carried nine passengers, and were very comfortable to travel in. A few post stages, which would accommodate twenty-six passengers, were run over this road, but the traffic was not heavy enough to bring them into general use. In 1864, Ben Halliday, whose name has been given to a street in Pocatello, secured a contract to carry the United States mails, and bought out Oliver and Conover. This line was later called the Halliday Overland Mail and Express, a name retained in the Overland Limited of today, on the Oregon Short Line and Union Pacific railroads.
