_North Dakota._ Prior to the opening of a state school, children were sent to schools in other states. In 1890 the state institution was created at Devil's Lake.[420] It is in charge of the state board of control.[421] On the admission of North Dakota as a state, 40,000 acres of the public land were set aside for the benefit of the school. It is further supported by a tax of six per cent of one mill on the assessed property valuation of the state.[422] _Ohio._ A movement was on foot for the establishment of a school at Cincinnati in 1821, but did not succeed. A private school was opened in 1827 at Tallmadge, which lasted two years. The state school was established at Columbus in 1829.[423] It is now in the hands of the state board of administration.[424] Five day schools are in operation in the state: Cincinnati, opened in 1886; Cleveland, 1892; Dayton, 1899; Ashtabula, 1903; and Toledo, 1911.[425] There are two private schools in Cincinnati: one, the Notre Dame, under the Sisters of Notre Dame, opened in 1890, and the other in 1906.[426] _Oklahoma._ Before creating an institution of its own, Oklahoma provided for the education of its deaf children in a private school at Guthrie, which had been opened in 1898.[427] In 1908 the state school was established at Sulphur,[428] and in 1909 a second school was opened at Taft, known as the Industrial Institute for the Deaf, the Blind and Orphans of the Colored Race.[429] The former school is directed by a board of four trustees, and the latter by a board of five regents, the state superintendent of public instruction being a member of each. The schools are related to the state department of education, and are inspected by that of charities.[430] _Oregon._ A private school was started at Salem in 1870, which in 1874 was taken over by the state.[431] It is now administered by the state board of control.[432] There is a day school in Portland, opened in 1908, and supported by the city.
