National color of the 4th Pennsylvania Infantry Regiment

The 4th Pennsylvania Infantry Regiment was an infantry regiment of the Union Army in the American Civil War. Formed mostly from a militia unit in Norristown in southeastern Pennsylvania, the regiment enlisted at the start of the war in April 1861 for a three-month period of service under the command of Colonel John F. Hartranft. The regiment served as part of the garrison of Washington, D.C., until late June, when it was sent into Northern Virginia to join the army of Brigadier General Irvin McDowell. The regiment suffered its only combat casualties in a picket action on June 30 and was sent back to be mustered out on the eve of the First Battle of Bull Run owing to disagreement among the men over remaining after their term of service expired. Its men were denounced as cowards for being members of the only regiment to refuse to fight at the July 21 battle. Hartranft and a company commander stayed with the army and both later received the Medal of Honor for their actions at Bull Run. (Full article...)

The pomelo (Citrus maxima) is the largest citrus fruit from the family Rutaceae and the principal ancestor of the grapefruit. It is a natural, non-hybrid citrus fruit, native to Southeast Asia. Growing on a tree 5–15 meters (16–50 feet) in height, the fruit is 15–25 cm (6–10 in) in diameter with a usual weight of 1–2 kilograms (2–4 pounds) and has a thicker rind than a grapefruit. It is divided into 11 to 18 segments and its flesh tastes like a mild grapefruit, with little of its common bitterness. The fruit generally contains few, relatively large seeds, but some varieties have numerous seeds.
