Higher means healthier safeguards. Choose any point to see that review below.
Each point is a dated review. The points are spaced evenly so every year is easy to select; the horizontal distance does not show the actual time between events. The 1861 reading is midnight because civil war replaced peaceful national problem-solving, even though the Union government continued to function.
