John H. Atchison, a pioneer resident of Pembina County, was born March 23, 1845 in Scotland. Mr. Atchison, together with his father, mother and brother left Scotland for Ontario, Canada in 1862. The immigrants were five weeks and three days in passage.

Mr. Atchison, together with Mr. Alexander Saunders left Pembina in May 1880. Mr. Atchison liked the land near Mr. Saunders and he took land just north of Mr. Saunders (NW 24-145-58).

As these settlers were near the mail route that ran from Valley City to Lee post-office, Mr. Saunders suggested that Mr. Atchison apply for an office. The application was made, and October 24, 1881, the post-office of Gallatin was started, with Mr. Atchison as the first postmaster. It was discontinued July 14, 1905 when rural free delivery displaced the country office. It was thought to be named by the postmaster for Gallatin County in southeastern Illinois.

The first winter, 1880-81, was long and hard. Nevertheless, hunters frequently came up the river. Deer, Antelope and Elk were often seen. One herd of 143 antelope being counted. The last herd of Antelope of any size was 43 seen in 1891. The hunters wanted hides and good specimen of Elk head for mounting, valued as high as $300.00.
