The Savannah River is a major river in the southeastern United States, forming most of the border between the states of South Carolina and Georgia. Two tributaries of the Savannah, the Tugaloo Rivers and the Chattooga River, form the northernmost part of the border. The Savannah River drainage basin extends into the southeastern side of the Appalachian Mountains just inside North Carolina, bounded by the Eastern Continental Divide. The ricer is about 350 miles long.

The Cistercian Abbey of St Mary and St Chad was founded in 1135 by Roger de Clinton, Bishop of Coventry (1129–1148). The abbey's location near the border of Wales meant it was destined to have a turbulent history. The abbey was closed in 1536 by the order of Henry VIII during the Dissolution of the Monasteries, whereupon the estate was granted to Lord Powis.

Kelso Abbey is a Scottish abbey built in the 12th century by a community of Tironensian monks who had moved from the nearby Selkirk Abbey. The monks constructed the Abbey on land granted to them by King David I. The construction commenced in 1128, and when completed fifteen years later, in 1143, it was dedicated to The Blessed Virgin and Saint John. The importance of the Abbey at that time was shown when King James III of Scotland was crowned at the Abbey in 1460. However, the Abbey's proximity to the border with England led to it suffering damage from cross-border raids. It was first damaged in the Anglo-Scottish wars at the start of the 1300s, but was later repaired by the monks.

The Mont Blanc (French for white mountain) or Monte Bianco (Italian 'White Mountain'), also known as "La Dame Blanche" (French, the white lady) is a mountain in the Alps. With its 4,810 m (15,781 ft) summit, it is the highest mountain in the Alps and Western Europe, and is ranked 11th in the world in topographic prominence. The mountain lies between the regions of Aosta Valley, Italy, and Haute-Savoie, France. The location of the summit is on the French-Italian border but Cartographers of France place it within its own boundaries on maps.

The hessian fly or barley midge, Mayetiola destructor, is a species of fly that is a significant pest of cereal crops including wheat, barley and rye. Though a native of Asia it was transported into Europe and later into North America, supposedly in the straw bedding of Hessian troops during the American Revolution (1775–83). There are usually two generations a year but may be up to five. In the spring the dark-coloured female lays about 250 to 300 reddish eggs on plants, usually where the stems are covered by leaves; the larvae feed on the sap and weaken the plants so that they cannot bear grain.

The Meadow Vole (Microtus pennsylvanicus), sometimes called the Field Mouse or Meadow Mouse, is a small North American vole found across Canada, Alaska and the northern United States. Its range extends further south along the Atlantic coast. One subspecies, the Florida Salt Marsh Vole, is found in Florida, and is classified as endangered. The Meadow Vole is active year-round, usually at night. It also digs underground burrows where it stores food for the winter and females give birth to their young. Although these animals tend to live close together, they are aggressive towards one other. This is particularly evident in males during the breeding season. It can cause damage to fruit trees, garden plants and commercial grain crops.

The American Goldfinch (Carduelis tristis), also known as the Eastern Goldfinch and Wild Canary, is a North American bird in the finch family. It is migratory, ranging from southern Canada to North Carolina during the breeding season, and from just south of the Canadian border to Mexico during the winter. The only finch in its subfamily which undergoes a complete molt, the American Goldfinch displays sexual dimorphism in its coloration; the male is a vibrant yellow in the summer and an olive color during the winter months, while the female is a dull yellow-brown shade which brightens only slightly during the summer. The male displays brightly colored plumage during the breeding season to attract a mate.

A windmill is a machine that is powered by the energy of the wind. It is designed to convert the energy of the wind into more useful forms using rotating blades or sails. The term also refers to the structure it is commonly built on. In much of Europe, windmills served originally to grind grain, though later applications included pumping water and, more recently, generation of electricity.
