"Greek Philosophy, which reached its highest excellence in Athens in the fourth century before Christ, had its origin two hundred years earlier i nthe ourlying settlements of the Hellenic race in Asia Minor, Thrace, Sicily, and Southern Italy, rather than in Greece proper. The founding of colonies and frequent changes of government in the older states led thoughtful men to study the constitution of man and of society." — The Delphian Society, 1913

"The section and ground plan of one of the older forms of open-mouthed furnaces used at Dowlais (Truran), consisting of a heavy mass of mascury, square at base, strongly braced together with iron tie-rods, rising in the shape of a truncated pyramid to the height of the boshes, and then surmounted with a conical top surrounded at the throat by a gallery for the introduction of the enarging materials. In the square base were four arched recesses or tuyere houses, one on each side, F, F, for the introduction of G also serving for the removal of cinder and the tapping of the furnace for the running of the pig. The lowest portion of the hearth or crucible, A, was constructed of refractory sandstone, grit, or conglomerate, or of difficulty fusible firebrick, the inner portion of the upper part of the furnace being also built of firebrick set in fireclay with an air course between the double lining thus constructed; exteriorly the furnace was built of less expensive and refractory materials, usually of stone, strongly bound round with iron hoops." — The Encyclopedia Britannica, 1893

As a kind of joke, John, King Henry's youngest son, had been called Lackland, because he had nothing when his brothers each had some great dukedom. The name suited him only too well before the end of his life. The English made him king at once. Richard had never had any children, but his brother Geoffery, who was older than John had left a son named Arthur, who was about twelve years old, and who rightly the Duke of Normandy and Count of Anjou. King Philip, who was always glad to vex whoever was king of England, took Arthur under his protection, and promised to get Normandy out of John's hands. However, John had a meeting with him and persuaded him to desert Arthur, and marry his son Louis to John's own niece, Blanche, who had a chance of being queen of part of Spain. Still Arthur lived at the French King's court, and when he was sixteen years old, Philip helped him to raise an army and go to try his fortune against his uncle. He laid siege to Mirabeau, a town where his grandmother, Queen Eleanor, was living. John, who was then in Normandy, hurried to her rescue, beat Arthur's army, made him prisoner and carried him off, first to Romen, and then to the strong castle of Falaise. Nobody quite knows what was done to him there. The governor, Hubert de Burgh, once found him fighting hard, though with no weapon but a stool, to defend himself from some ruffians who had been sent to put out his eyes. Hubert saved him from these men, but shortly after this good man was sent elsewhere by the king, and John came himself to Falaise. Arthur was never seen alive again, and it is believed that John took him out in a boat in the river at night, stabbed him with his own hand, and threw his body in the river.

Leaves - simple; alternate; edge lobed; (edge of the lobes entire or sometimes coarsely notched and hollowed at their ends.) Outline - reverse egg-shape. Apex - of lobes, rounded. Base - wedge-shape. Leaf - quite variable in size and shape; four to seven inches long; smooth; pale beneath; the lobes oftenest five to nine, long and narrow, and sometimes widening toward the end, but at other times only three to five, short and broad, and radiating obliquely from the middle rub. Bark - of trunk, slightly roughened (comparatively smooth for an oak), light-gray; in older trees loosening in large, thin scales; the inner bark white. Acorns - usually in pairs on a stem one fourth of an inch or more in length. Cup - rounded saucer-shape, not scaly, but rough and warty and much shorter than the nut. Nut - three fourths to one inch long, slightly egg-shape or oval; brown, sweet, and edible. October. Found - from Ontario and the valley of the St. Lawrence southward to Florida, and westward to Southeastern Minnesota, Arkansas, and Texas. Its finest growth is on the western slopes of the Alleghany Mountains, and in the Ohio basin. General Information - A noble tree, sixty to eighty feet or more in height, with hard, touch wood of very great value in many kinds of manufacturing, and for fuel. The withered, light-brown leaves often cling throughout the winter. The "oak-apples" or "galls" often found on oak-trees are the work of 'gall-flies" and their larvae. When green tiny worms will usually be found at their centre. Quaint reference is made to these galls in Gerardes' "Herbal": "Oak-apples being broken in sunder before they have an hole thorough them do fore shewe the sequell of the yeere. If they conteine in them a flie, then warre insueth; if a creeping worme, then scarcitie of victuals; if a running spider, then followeth great sickness or mortalitie." The oak, probably more than any other tree, has been associated with workshop of the gods. The "Talking Tree" of the sanctuary in Dodona (the oldest of all the Hellenic sanctuaries, and second in repute only to that at Delphi) was an oak. Oak groves were favorite places for altars and temples of Jupiter. The Druids worshipped under the oak-trees. Quercus, possible from a Celtic word meaning to inquire, because it was among the oaks that the Druids oftenest practised their rites.

Cones - four to six inches long, cylinder-shape, about one inch in diameter before the scales loosen; solitary, drooping, slightly curved. Scales - thin, without prickles. Bark - of trunk, lighter than in the other pines; in young trees smooth, and only slightly rough when older. Found - from Newfoundland to the Winnipeg River, southward through the Northern States, and along the Alleghany Mountains to Georgia. Its finest growth is in the region of the Great Lakes. General Information - An evergreen tree of soft and delicate foliage, eighty to one hundred and fifty feet high; one of the most valuable timber trees of any country. The wood is clear of knots, straight-grained, and soft, and is used in immense quantities for building and many kinds of manufacturing. The branches are given off in flat, regular whorls around the straight trunk.

Leaves - simple; indeterminate in position because of their closeness; arranged singly all around the branchlets. Leaf - needle-shaped, five twelfths to three fourths of an inch long, four-sided, curved, sharp, rather slender, bluish-green, much lighter than the leaf of the Black Spruce. Bark - lighter than that of the Black Spruce. Cones - five inches and more in length; about one and a half inches in thickness. Branches and branchlets - heavily drooping, especially in the older trees. Scales - broad reverse egg-shape, with an entire edge, and rounded or somewhat two-lobed at the apex.

Genus Picea, Link. (Spruce)

Leaves - simple; indeterminate in position because of their closeness; arranged singly all around the…

Leaves - simple; indeterminate in position because of their smallness and closeness. They are arranged in four rows up and down the branchlets. In younger or rapidly growing sprouts the leaves are awl-shaped or needle-shaped, somewhat spreading from the branch, very sharp and stiff, placed in pairs (or sometimes in threes), usually about one fourth of an inch long, and with the fine branchlets, which they cover, rounded. In the older and slower-growing trees the leaves are scale-like and overlapping, egg-shape, closely pressed to the branchlets which they cover, and with the branchlets square. As the branchlets grow, the lower scales sometimes lengthen and become dry and chaffy and slightly spreading. Bark - brown and sometimes purplish-tinged, often shredding off with age and leaving the trunk smooth and polished. Berries - about the size of a small pea, closely placed along the branchlets, bluish, and covered with a whitish powder. Found - in Southern Canada, and distributed nearly throughout the United States - more widely than any other of the cone-bearing trees. General information - An evergreen tree, fifteen to thirty feet high (much larger at the South), usually pyramid-shaped, with a rounded base, but varying very greatly, especially near the coast, where it is often twisted and flattened into angular and weird forms. The wood is very valuable, light, straight-grained, durable, fragrant. It is largely used for posts, for cabinet-work, for interior finish, and almost exclusively in the making of lead pencils. The heart-wood is usually a dull red (whence the name), the sap-wood white. Among the most picturesque objects in the Turkish landscape, standing like sentinels, singly or in groups, and slender and upright as a Lombardy Poplar, are the black cypress trees (C. sempervirens). They mark the sites of graves, often of those which have long since disappeared. In America, more than any other northern tree, the red cedar gives the same sombre effect, whether growing wild or planted in cemeteries. The Common Juniper (J. communis, L.), common as a shrub, is occasionally found in tree form, low, with spreading or drooping branches, and with leaves resembling those of a young Red Cedar, awl-shaped and spreading, but arranged in threes instead of opposite.

Leaves - compound (odd-feathered; leaflets, five); alternate; edge of leaflets sharp-toothed. Outline - of leaflet, long oval, reverse egg-shape or egg-shape, the lower pair differing in shape from the others, and much smaller. Apex - long-pointed. Base - of the end leaflet, wedge-shape; of the others, more or less blunted. Leaf/Stem - rough throughout. Buds - large and scaly, often of a green and brown color. Leaflet/Stems - lacking (or scarcely noticeable), excepting the roughish stem of the end leaflet. Leaflets - four to eight inches long; roughish below. Bark - dark and very rough in the older trunks, peeling up and down in long, shaggy strips. Often the strips cling at their middle and are loose at each end. Fruit - round, nearly one and a half to two inches in diameter; the husk, thick (nearly half an inch), depressed at the center, grooved at the seams, and wholly separating into four inches at maturity; the nut, about one inch long, often the same in breadth, slightly flattened at the sides, angular, nearly pointless, whitish, with a rather this shell, and a large finely flavored kernel. October. Found - from the valley of the St. Lawrence River to Southeastern Minnesota, and southward to Western Florida. Its finest growth is west of the Alleghany Mountains. General Information - A tree, fifty to eighty feet high, of great value. Its tough and elastic wood is used in making agricultural implements, carriages, axe-handles, etc. It ranks also among the best of woods for fuel. Most of the "hickory nuts" of the markets are from this species. All the Hickories are picturesque trees. Their tendency, even when standing alone, is to grow high, and with heads that, instead of being round, are cylinder-shaped to the very top, with only enough breaks and irregularities to add to the effect. This tendency is more marked in the Hickories than in any other of the leaf-shedding trees of North America. They are worthy of the name sometimes given them of 'the artist's tree." Hicoria, from a Greek word meaning round, in allusion to the shape of the nut.

Orgyia leucostigma, the White-marked tussock moth, is a moth in the family Lymantriidae. The caterpillar is very common especially in late summer in eastern North America, as far west as Texas, Colorado, and Alberta. There are two or more generations a year in eastern North America (Wagner 2005). They overwinter in the egg stage. Eggs are laid in a single mass over the cocoon of the female, and covered in a froth (Wagner 2005). Up to 300 eggs are laid at a time. he larvae are brightly coloured, with tufts of hair-like setae. The head is bright red, the body has yellow or white stripes, with a black stripe along the middle of the back. There are bright red defensive glands on the hind end of the back. Four white toothbrush-like tufts stand out from the back, and there is a grey-brown hair pencil at the hind end. Touching the hairs will set off an allergic reaction in many humans (Wagner 2005). Young larvae skeletonize the surface of the leaf, while older larvae eat everything except the larger veins (Rose and Lindquist, 1982). They grow to about 35 mm.

Chess is a recreational and competitive game played between two players. Sometimes called Western chess or international chess to distinguish it from its predecessors and other chess variants, the current form of the game emerged in Southern Europe during the second half of the 15th century after evolving from similar, much older games of Indian and Persian origin. Today, chess is one of the world's most popular games, played by millions of people worldwide at home, in clubs, online, by correspondence, and in tournaments.

John Wilkes (17 October 1725 &ndash; 26 December 1797) was an English radical, journalist and politician. In the Middlesex election dispute, he fought for the right of voters&mdash;rather than the House of Commons&mdash;to determine their representatives. In 1771 he was instrumental in obliging the government to concede the right of printers to publish verbatim accounts of parliamentary debates. In 1776 he introduced the first Bill for parliamentary reform in the British Parliament. Wilkes' increasing conservatism as he grew older caused dissatisfaction among radicals and was instrumental in the loss of his Middlesex seat at the 1790 general election. Wilkes then retired from politics and took no part in the growth of radicalism in the 1790s.

In geology and related fields, a stratum (plural: strata) is a layer of rock or soil with internally consistent characteristics that distinguishes it from contiguous layers. Each layer is generally one of a number of parallel layers that lie one upon another, laid down by natural forces. They may extend over hundreds of thousands of square kilometers of the Earth's surface. Strata are typically seen as bands of different colored or differently structured material. Individual bands may vary in thickness from a few millimeters to a kilometer or more. Each band represents a specific mode of deposition -- river silt, beach sand, coal swamp, sand dune, lava bed, etc. Eozoic strata pertains to rocks or strata older that the Paleozoic, in many of which the eozoön has been found.
