Rochester Castle stands on the east bank of the River Medway, in Rochester, Kent. It is one of the best-preserved castles of its kind in the UK. There has been a castle on this site since Roman times (c <small>AD</small>43), though it is the keep of 1127 and the Norman castle which can be seen today. With the invention of gunpowder other types of defense became more appropriate, and the military center of the Medway Towns moved to Chatham.

Lambeth Palace is the official London residence of the Archbishop of Canterbury. It is located in Lambeth, on the south bank of the River Thames a short distance upstream of the Palace of Westminster on the opposite shore. It was acquired by the archbishopric around 1200. The so-called Lollard's Tower, which retains evidence of its use as a prison in the 17th century, dates from 1440.

Her Majesty's Royal Palace and Fortress, more commonly known as the Tower of London (and historically as The Tower), is a historic monument in central London, England, on the north bank of the River Thames. The Tower of London is often identified with the White Tower, the original stark square fortress built by William the Conqueror in 1078. However, the tower as a whole is a complex of several buildings set within two concentric rings of defensive walls and a moat. The tower's primary function was a fortress, a royal palace, and a prison (particularly for high status and royal prisoners).

Westover Plantation is located on the north bank of the James River in Charles City County, Virginia. It is located on State Route 5, a scenic byway which runs between the independent cities of Richmond and Williamsburg. It is a US National Historic Landmark. Westover Plantation was formerly claimed to have been built circa 1730 by William Byrd II, the founder of Richmond; this date appears in the 1960 designation of the house as a National Historic Landmark. However, recent dendrochronologic testing on boards and planks in the house shows that they actually date to the 1750s, and this is the date of construction now recognized by the National Park Service. Therefore the house was probably built by William Byrd III, not his father William Byrd II. The house is noteworthy for its secret passages, magnificent gardens, and architectural details. The grounds and garden are open 9 a.m. to 6 p.m. daily, but the house is not open to the public.

After a fire in 1834, the present Houses of Parliament were built over the next 30 years. They were the work of the architect Sir Charles Barry (1795&ndash;1860) and his assistant Augustus Welby Pugin (1812&ndash;52). The design incorporated Westminster Hall and the remains of St Stephen's Chapel. The Palace of Westminster, also known as the Houses of Parliament or Westminster Palace, in London, England, is where the two Houses of the Parliament of the United Kingdom (the House of Lords and the House of Commons) meet. The palace lies on the north bank of the River Thames in the London borough of the City of Westminster, close to other government buildings in Whitehall.

Johann Gottlieb Rall (ca. 1726 - December 26, 1776 ) was a German colonel in command of Hessian troops in Trenton, New Jersey. By 1776, Rall belonged to the infantry regiment of the 1st Division under General Phillip Leopold von Heister and commanded approximately 1,200 men fighting for Great Britain in the American Revolutionary War. He was at the Battle of Brooklyn at Flatbush, the Battle of White Plains, the Battle of Long Island, and figured prominently in the Battle of Trenton. At the Battle of Trenton, Rall was mortally wounded and taken back to his headquarters where he died. <p>"Rall's head-quarters. This is a frame building standing upon Warren Street, opposite Perry, near the corner of Bank Alley. The buildings on the left are also of ante-Revolutionary origin. This house was a tavern at the time, kept by Stacey Potts, the grandfather of Stacey G. and Joseph C. Potts, Esqrs., of Trenton. In a pane of glass, in the front window on the left of the front door, lower story, may be seen a hole made by a bullet, shot during the battle. Colonel Rall died in the front room in the second story, immediately over this window. It is related that a daughter of Mr. Potts, who was at a neighbor's when the firing commenced, was running toward her father's house, when a musket-ball struck her comb from her head and slightly injured her scalp."—Lossing, 1851

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 Sand Martin (Riparia riparia) is a migratory passerine bird in the swallow family. This species was first described by Linnaeus in his Systema naturae in 1758 as Hirundo riparia.Riparia means "of the riverbank", and is derived from the Latin ripa, a riverbank. It has a wide range in summer, embracing practically the whole of Europe and the Mediterranean countries, part of northern Asia and also North America, where it is called Bank Swallow. It winters in eastern and southern Africa, South America and South Asia (where it is called the Collared Sand Martin).

The Fall Army Worm (Spodoptera frugipeda) is part of the order of Lepidoptera and are the caterpillar life stage of a moth. They are native to tropical regions of the western hemisphere, from the United States to Argentina. They are regarded as pests and are known to wreak havoc with crops if left to multiply. Their name is derived from their feeding habits. The army worms are some of the most destructive pests to agricultural crop in the world. Once the food supply is exhausted the entire "army" of worms will move to the next available food source.

An illustration of Cochineal living on cactus. Cochineal is the name of both crimson or carmine dye and the cochineal insect (Dactylopius coccus), a scale insect in the suborder Sternorrhyncha, from which the dye is derived. This type of insect, a primarily sessile parasite, lives on cacti from the genus Opuntia, feeding on moisture and nutrients in the cacti. The insect produces carminic acid which deters predation by other insects. Carminic acid can be extracted from the insect's body and eggs to make the dye. Cochineal is primarily used as a food colouring and for cosmetics.

Lemmings are small rodents, usually found in or near the Arctic, in tundra biomes. Together with the voles and muskrats, they make up the subfamily Arvicolinae (also known as Microtinae), which forms part of the largest mammal radiation by far, the superfamily Muroidea, which also includes the rats, mice, hamsters, and gerbils. Lemmings do not hibernate through the harsh northern winter. They remain active, finding food by burrowing through the snow and utilising grasses clipped and stored in advance. They are solitary animals by nature, meeting only to mate and then going their separate ways, but like all rodents they have a high reproductive rate and can breed rapidly in good seasons.

Fennel (Foeniculum vulgare) is a plant species in the genus Foeniculum (treated as the sole species in the genus by most botanists). It is a hardy, perennial, umbelliferous herb, with yellow flowers and feathery leaves, grows wild in most parts of temperate Europe, but is generally considered indigenous to the shores of the Mediterranean, whence it spreads eastwards to India and even in England in Bedfont Lakes Country Park and Thurrock . It has followed, especially where Romans have colonized, and may be found growing wild in many parts of the world upon dry soils near the sea-coast and upon river-banks. It is a member of the family Apiaceae. It is a highly aromatic and flavorful herb with culinary and medicinal uses, and is one of the primary ingredients of absinthe. Fennel is used as a food plant by the larvae of some Lepidoptera species including the Mouse Moth and the Anise Swallowtail.

The gourami or gouramies are a family, Osphronemidae, of freshwater perciform fishes. The fish are native to Asia, from Pakistan and India to the Malay Archipelago and north-easterly towards Korea. "Gouramies" is an example of a redundant plural, like "cherries" or "Pakistanis"; Gourami is already plural, in its original language. The most famous species of gourami is the "kissing gourami", who do literally lock their exaggerated lips to each other in social displays relating to mating, as a habit of aggression toward other fish of any species, and for seeking food.

An illustration of a common flea. Once the flea reaches adulthood its primary goal is to find blood - adult fleas must feed on blood in order to reproduce. Adult fleas only have around a week to find food once they emerge, though they can survive two months to a year between meals. A flea population is unevenly distributed, with 50 percent eggs, 35 percent larvae, 10 percent pupae and 5 percent adults. Their total life cycle can take as little as two weeks, but may be lengthened to many months if conditions are unfavorable. Female fleas can lay 500 or more eggs over their life, allowing for phenomenal growth rates.

An illustration of duckweed. Duckweed is an important food source for waterfowl and are eaten by humans in some parts of Southeast Asia (as khai-nam). Some duckweeds are used in freshwater aquariums and ponds where they may spread rapidly, although in a large pond they may be difficult to eradicate once established. The plants can provide nitrate removal (if cropped) and cover for fry. The plants are used as shelter by pond water species, such as bullfrogs and bluegills. The duckweeds are important in the process of bioremediation because they grow rapidly, absorbing excess mineral nutrients, particularly nitrogen and phosphates. A cover of duckweeds will reduce evaporation of water compared to a clear surface.

The Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight. They are members of subfamily Cetoniinae, within the scarab beetle family. Goliath beetles can be found in many of Africa's tropical forests, where they feed primarily on tree sap and fruit. Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods such as commercial cat and dog food. Goliath beetles measure from 60&ndash;110 millimetres (2.4&ndash;4.3 in) for males and 50&ndash;80 millimetres (2.0&ndash;3.1 in) for females, as adults, and can reach weights of up to 80&ndash;100 grams (2.8&ndash;3.5 oz) in the larval stage, though the adults are only about half this weight. The females range from a dark brown to silky white, but the males are nomally brown/white/black or black/white.
