It doesn't like it when I use other toothpastes.
Reaper patentIn 1834, Cyrus Hall McCormick received a patent for his reaping machine, recognized as the first such practical machine. He demonstrated his machine in 1831 at a public trial in a field near Walnut Grove, Va. The owner of the field, fearing the machine would rattle the heads of his wheat, stopped the demonstration, which was then moved to a more level field on the neighbour's farm. There, the test was impressive, cutting six acres in a half a day. Although it did the work of six men, it was very difficult to popularize, and it took until 1841 before McCormick sold his first two machines. In 1902, the McCormick Harvesting Machine Company merged with five other leading farm implement manufacturers to form the International Harvester Company. |
