Calvert county has 222 square miles of territory, and is the smallest in the state. It dates back to 1654, and preserves the family name of the proprietary. The Patuxent curves around the southern and western sides of the county, and its eastern line is washed by the Chesapeake. The bayside is marked by highlands, and the "Cliffs of Calvert " attract much attention among students of geology and physiography. The soil is productive, and divided between sandy and clay loams. Tobacco and cereals are the chief crops, and a considerable number of the people are interested in fisheries. The oyster grounds of Calvert are among the best in the state. Timber is plentiful, and iron ores and silica are found in extensive deposits. Drum Point, at the mouth of the Patuxent, has one of the finest harbors in the United States, and in time may become the location of a vast Federal or commercial maritime enterprise. Fruits and vegetables mature early on the sheltered lands, with southern exposure, along the waterways. The county seat is Prince Frederick, which is centrally located, and, like other Calvert towns, is small in population. Solomon's, in the southern part of the county, 26 miles from Prince Frederick, has a marine railway and shipyards, and Sellers', on St. Leonard's creek, St. Leonard's, Chaneyville, Lower Marlboro, Drum Point, Huntingtown, Plum Point, are among the villages of the county. In the colonial and early state history of Maryland Calvert was conspicuous. The first railroad to enter the county is the Chesapeake Beach, which was built from Hyattsville, near Washington, to the bay a few years ago, and runs for a short distance through the upper part of Calvert. A large portion of the population is colored. Among noteworthy sons of the county were General James Wilkinson and Rev. Mason Weems ("Parson Weems"), the once popular biographer, who pointed a moral with his celebrated myth of little George Washington, his hatchet, and his father's cherry tree.
