The New International Encyclopædia…
“ The coastal plain embraces that part of Maryland lying to the east of a line passing from Washington to Baltimore, Havre de Grace, and Wilmington. It includes more than half the land area of the State, and is divided by Chesapeake Bay into what is commonly called the ‘eastern shore’ and the ‘western shore’ or Southern Maryland. The ‘eastern shore’ is low and level; only in the north does it reach 100 feet, and most of it is less than 25 feet above the sea. The ‘western shore’ is higher, and rises to 300 feet near the District of Columbia and again near Baltimore. ”
