A coastal plain in the first cycle of erosion. The presence of two hard layers produces a terraced cuesta front. In exceptional cases the upper terrace may weather back with sufficient rapidity to constitute a second cuesta with a lowland of some width between it and the lower cuesta, if the weak stratum between the harder is of sufficient thickness.

The United States Capitol serves as the seat of government for the United States Congress, the legislative branch of the U.S. federal government. It is located in Washington, D.C., on top of Capitol Hill at the eastern end of the National Mall. Although not in the geographic center of the District of Columbia, the Capitol is the origin by which the quadrants of the district are divided. Officially, both the east and west sides of the Capitol are referred to as "fronts." Historically, however, the east front was initially the side of the building intended for the arrival of visitors and dignitaries.

Kiwi, Apteryx australis, of the South Island, is lighter (than the Apteryx mantelli of North Island), and feels soft instead of harsh when grasped." "These birds are at once distinguished from all their allies by their small size, and by the long, weak, decurved bill, which tapers regularly and has the nostrils placed almost at the extremity. The head and eyes are comparatively small... The legs are very stout and situated backwardly, a small elevated hallux is present, and the toes are provided with long, sharp claws. The wings are small-boned and invisible, with functionless quills, the tail is rudimentary, the aftershaft and the furcula are absent, while many elongated hairs occur on the front of the head." - A. H. Evans, 1900

View of a village in the Schwartzwald, or Black Forest. The Black Forest stands in the elbow formed by the Rhine river in its course from Schaffhausen to Basle, and from Basle to Mannheim. It is bounded by the plain that borders the river The Neckar River bounds it on the north, while on the east it is limited by the upper part of the same river, and by an imaginary line drawn from the source of the Neckar to Schaffhausen. The Black Forest owes its gloomy name to the dark aspect of its peaks and slopes which is shadowed by pine-trees. On the brightest day the forest's trees still retain their shadow.

View of the castle framed by an arch. A landmark of Heidelberg, the castle ruins are among the most important Renaissance structures north of the Alps. The castle has only been partially rebuilt since its demolition in the 17th and 18th centuries. It is served by an intermediate station on the Heidelberger Bergbahn funicular railway that runs from Heidelberg's Kornmarkt to the summit of the Königstuhl. The earliest castle structure was built before 1214 and later expanded into two castles circa 1294; however, in 1537, a lightning-bolt destroyed the upper castle. The present structures had been expanded by 1650, before damage by later wars and fires. In 1764, another lightning-bolt destroyed some rebuilt sections.

Schloss Hohenaschau, is the dominating feature in the town of Aschau im Chiemgau in Bavaria. The huge castle was first built around 1165. This picturesque castle is situated on a hill, overlooking the Prien River. The rear facade of Schloss Hohenaschau, although not as ornate as the front side of the castle, is still quite impressive. From some views, the castle appears to grow directly out of a rock cliff.

The collegiate church of St. Peter was built in the Romanesque style in the twelfth century. The burial ground of St. Peter is situated directly south of the church and is the most ancient place of sepulture in Salzburg. In this view, we see the churchyard, situated at the base of an overhanging rock, from which hangs rich and luxurious foliage; before us, in the open space, are monuments in every style of mortuary design, while cowled monks kneel before the ancient symbol of Christianity, or converse together within this sacred enclosure.

The Gloriette at Schönbrunn, a elegant pavilion is a miniature reproduction of the Palace of Schönbrunn. A gloriette (from the 12th century French for "little glory") is a building in a garden erected on a site that is elevated with respect to the surroundings. The structure and shape can vary greatly, often in the form of a pavilion or tempietto, more or less open on the sides. The Gloriette at Schönbrunn is a pavilion with two wings that are open porticos with a beautiful view of the city from its rooftop.

"Aegialitis hiaticola, the Ringed Plover, Sand-Lark, or Stone-runner, mistakenly called the "Ring-Dotterel" which is common on the British coasts and even inland, extends from Smith's Sound eastward to Bering Strait, and migrates to South Africa, North India, or accidentally, Australia. It breeds as far south as the Atlantic Islands, North Africa, and Turkestan. The plumage is light brown, with white forehead, post-ocular streak, upper neck, alar bar, outer rectrices, and under surface; the crown, lores, cheeks, and a collar-broader in front-being black. The young lack the black crown." A. H. Evans, 1900

The head is white in front, with an intervening black lateral stripe; the wings are mainly white, with curious filamentous appendages to the attenuated blackish outer primaries; the four median feathers of dark brown tail are enormously elongated and decurved. The winter and immature plumage is almost entirely bronzy-brown, with white under surface crossed by a black gorget; but the young have a rufous head." A. H. Evans, 1900

"Steam is admitted under pressure for a boiler into a metal cylinder behind a piston, as represented in figure 14. Its pressure drives the piston forward, doing useful work. When the piston has moved through a part of its stroke the steam supply is cut off, the stroke is completed by the expansion of the steam confined in the cylinder. By the first law of thermodynamics this expansion cools the steam, since work is done in the process; but the expansion is not adiabatic, since the cylinder and piston give up some heat to the steam within. At the end of the stroke the exhaust valve opens and the cooled steam escapes into the atmosphere or condenser through exhaust pipe A. The operation is then repeated on the other side of the piston." Louis Derr, 1911
