In its early years Grand Forks was a typical river town, developing into an important station for the heavy river and oxcart traffic on the St. Paul-Fort Garry trail. Dwellings began to dot the prairie beside the river, log huts and crude frame structures built from the product of Captain Griggs' sawmill. A post office was established in 1871, and mail arrived once or twice a week by dog team. In the same year a telegraph station was established, on the first line in the State, running between Fort Abercrombie and Winnipeg. It was about this time that the English pronunciation of the community's name came into general use. In the winter of 1872 there was much unemployment and saloons were filled with idle men. During this winter "Catfish Joe," a half-witted Frenchman, murdered a local character known as Old Man Stevens who, while intoxicated, called him uncomplimentary names. The saloon crowd decided on a lynching, and all through the night plans were discussed, but with so many rounds of drinks that action was impossible. Catfish Joe was tried for murder at Yankton, spent two years in prison, and returned to terrify Grand Forks by strutting about the streets decorated with a bowie knife and a Winchester. One courageous townsman, Bert Haney, seized the gun and struck Joe a terrific blow on the head, breaking the rifle barrel from the stock, but with no damage to Joe's head. Catfish Joe later went to Montana where he murdered his partner for refusing to get up in the night and prepare breakfast. By the spring of 1872 Captain Griggs' sawmill was doing a flourishing business, turning out lumber for building and repairing river boats and barges. Logs were cut and floated down the river to Winnipeg. When Frank Viets opened the first flour mill in the Red River Valley at Grand Forks in 1877, he added another industry to the growing settlement. The Hudson's Bay Company operated a store, managed by Viets, who purchased it when the company moved to Winnipeg in 1877. Since five families in the city had children of school age in 1873, it became necessary to establish a school. As some of the families lived on North Third Street and others in the Lincoln Park area, they could not agree on a suitable location, and each faction held a school of its own. Claim shanties served as school buildings, and a drayman, one of Captain Griggs' hired men, taught the north end school. There was no dentist in the community in the early days of Grand Forks. Alex Walstrom, a blacksmith, used a pair of homemade tongs about two feet long to pull aching teeth. On October 26, 1875, Captain Griggs filed a plat of the original town site of Grand Forks, covering 90 acres of his claim. The following spring Viets filed the plat of his first addition. In 1879 the village of Grand Forks was organized and three years later was incorporated as a city.
