advertise barbed wire there. In 1881, Sanborn purchased ninety-five sections of land in southwestern Potter County from near the Canadian River extending into Randall County south of Amarillo. Included in the purchase was Tecovas Spring, once a watering site and a trading post for Indians and Comancheros. John Summerfield, a surveyor from Sherman, Texas, reported a constant flow of freshwater from the spring. Sanborn chose this site for his ranch headquarters and enclosed 120 miles of land in barbed wire for $39,000 ($ in dollars). Warren W. Wetzel, also of Sherman, used cedar posts brought from both the Palo Duro Canyon and the breaks of the Sierrita de la Cruz in the northwestern portion of the ranch to hold up the wire. Besides ranchers, railroads were large purchasers of barbed wire, so that cattle did not stray onto their tracks. The Frying Pan Ranch soon had 15,000 head of cattle, and 125,000 more acres were added. Later the ranch was divided. In 1898, Glidden deeded Frying Pan Ranch to his son-in-law William Henry Bush. Between 1908 and 1920, William Henry Bush and his second wife Ruth Bush built a larger ranch house near Tecovas Spring, which later became the residence of Stanley Marsh 3 and his wife, Wendy. Gwendolyn “Wendy” Bush O’Brien was the daughter of Emeline Bush and her husband Frank O’Brien; Emeline was a daughter of William Henry and Ruth Bush. Stanley Marsh called the estate “Toad Hall.” Land for the Northern Illinois State Normal School Glidden, a former teacher, gave 63 acres (255,000 m2) of his homestead as a site for the Northern Illinois State Normal School. The school opened on September 12, 1898, with 139 students and 16 members of the faculty. The school's name was changed to Northern Illinois University in 1957. The town of Glidden, Iowa, is named in his honor. Personal life He and his wife Lucinda had one daughter, Elva Frances, in 1851. She married William Henry Bush in DeKalb on February 1, 1877. His wife Lucinda died on October 28, 1895. Elva died in 1906 not long before her father died, and is buried in the Glidden family plot in a cemetery in DeKalb. In 1898, Glidden deeded his Frying Pan ranch in Texas to his son-in-law, W. H. Bush. Bush married again in 1908, after being widowed, to Ruth Russell Gentry. He is buried in Graceland Cemetery in Chicago. In
