This cache is near the Kidder Institute about 4 feet off the ground. Take a look at the architecture of the nearby buildings.
Kidder, MO, a village of 270 people, was settled by people from New England (Note the sailing ship in the school logo) who valued education; thus it was called the “Athens of Caldwell County.” The original school in Kidder was the Thayer College and High School (1871-76), created by Nathaniel Thayer. Classes began in a vacant store building while a new building was completed. Frank Shaw reported that the curriculum was largely preparatory and the pupils were mostly local, but that some of the out-of-town boys lived on the upper floor of the new school. In 1876 the school was foreclosed. It reopened in 1877 as Kidder Institute, under the auspices of the Congregational Church of Missouri. In 1884 G. L. Ramsey became director, raising the school to a stable position. He was succeeded by G. W. Shaw, who directed the school until his death in 1932. A Junior College division was added in 1922. The school closed after Shaw’s death. In 1934 the campus became Shaw Memorial School, the public elementary and high school for Kidder.
