Leave watermelon uncut, out of the fridge for up to two weeks. Watermelon (Citrullus lanatus) can take a long time to mature and for excited gardeners, the temptation to harvest fruits early may be high. Once picked, watermelon fruits stop ripening and fruits picked too early may be destined for the compost pile instead of the dinner table. It's important to allow your watermelon time to reach full maturity in the garden. Know the signs that your watermelon has ripened to avoid early harvest.
In 1798, Congress established the U. S. Marine Hospital Service -- the predecessor of today's U.S. Public Health Service -- to provide health care to sick and injured merchant seamen.
In 1789 the U.S. Marshals Service was established, followed by other federal services such as the U.S. Parks Police (1791) and U.S. Mint Police (1792). The first city police services were established in Philadelphia in 1751, Richmond, Virginia in 1807, Boston in 1838, and New York in 1845. The U.S. Secret Service was founded in 1865 and was for some time the main investigative body for the federal government.
