who established an experimental farm at mount vernon
Mount Vernon The tobacco market had declined and many planters in northern Virginia converted to mixed crops. Like them, by 1766 Washington had ceased growing tobacco at Mount Vernon and replaced the crop with wheat, corn, and other grains. Besides hemp and flax, he experimented with 60 other crops including cotton and silk. He also derived income from a new gristmill which produced cornmeal and flour for export and also ground neighbors' grain for fees. Washington similarly sold the services of the estate's looms and blacksmith. He built and operated a small fishing fleet, permitting Mount Vernon to export fish. Washington also practiced the selective breeding of sheep in an effort to produce better quality wool.
Mount Rushmore Originally known to the Lakota Sioux as "The Six Grandfathers",[11] the mountain was renamed after Charles E. Rushmore, a prominent New York lawyer, during an expedition in 1885.[12] At first, the project of carving Rushmore was undertaken to increase tourism in the Black Hills region of South Dakota. After long negotiations involving a Congressional delegation and President Calvin Coolidge, the project received Congressional approval. The carving started in 1927 and ended in 1941 with no fatalities.[13]
