In 1868 Joshua Harley brought his bride, Lucretia, to Chickasaw Nation and went into contract with the Chickasaw Nation as head of the school. They both served as teachers at the institute. Working alongside her husband during these long, difficult years to bring education to the Chickasaw children, Mrs. Harley bore four children, two of whom died in infancy to be buried in the cemetery adjacent to the old Academy. The school under Harley's leadership soon took his name and was known as Harley Institute.  Between 1880 and 1885, the Chickasaw School suffered several fires and finally tribal authorities decided it would be more expensive to repair the structure than to build a new one. Moreover, the old location had proven unhealthy, some thought due to bad water and waste disposal. Professor Harley died at the school December 24, 1892 and his wife carried on to the end of the school term.  A flood in the early summer (1853) damaged the saw-mill, overflowed the corn field and swept away part of the fence. The water rose in a few hours to many feet higher than had been ever known and the loss to the school amounted to $2,000. About 170,000 bricks had been burned (fired) for additional buildings at the academy. One such building was to be a three-story structure, 52 feet long by 22 feet wide. Six rooms were to be 19 feet square in the clear, with a fireplace in each. Two small bedrooms were to be cut off the halls on the second and third floors. The new mill was directly across at the south end of the old building, which formed a right angle with the new. A well had been dug 50 feet deep in the yard and it supplied excellent water and a "horse-power" erected for general purposes. Rev. Robinson remained at the academy until 1859. The school became so identified with the superintendent that it was generally known as the Robinson Academy.In the early 1900's, farm fields extended far beyond the refuge wildlife plantings of today. The residents of Washita Farms, also known as Chapman Farms, not only grew crops in the first half of the century here, but also raised hogs and thousands of chickens and turkeys. The farm encompassed a community of 53 residences, a brick school, frame church, concrete silos, and a concrete store. The store is still used as the refuge office/shop building. Some of the concrete houses are still used by refuge employees.In 1946 the federal government purchased the Roxie A. Chapman Estate as part of a much larger impoundment area for the Denison Dam in Texas, which created Lake Texoma. At that time 16,464 acres of land and water were set aside to become the Tishomingo National Wildlife Refuge.
