"Among the larger and more splendid moths of our own country is the Luna Moth, or Green Emperor Moth, <em>attacus luna</em> a large and beautiful species, common in the Northern United States. The wings, which are drawn out into what appears like a long tail, are of a light yellowish-green color, marked with eye-spots near the middle. The expanse of the wings is four inches. The caterpilar lives on walnut-trees, and spins a cocoon of which silk might be made. Many of these cocoons may be picked up on the ground, in autumn or spring, beneath the trees frequented by these insect."  &mdash; Goodrich, 1859

"Most of the great diamonds distinguished for beauty and size have very interesting histories. one of the most famous is the Koh-i-Nur, or Koohinoor, 'Mountain of Light.' The legend is that it was carried by the hero Karna, whose deeds are celebrated in the 'Mahabharata.' It made its first appearance in history in the 14th century, when Ala-ed-din brought it to Delhi. At that time it was supposed to weigh 793 carats."&mdash;(Charles Leonard-Stuart, 1911)

"Eddystone is a group of gneiss rocks, daily submerged by the tide, in the English Channel, 9 miles off the Cornish coast, and 14 S.S.W. of Plymouth Breakwater. The frequent shipwrecks on these rocks led to the erection of a lighthouse on them in 1669-1700, but the great storm of Nov. 20, 1703 completely washed it away. Another lighthouse was built in 1706-1709. This was burned in 1755. The next, noted for its strength and the engineering skill displayed in it, was constructed in 1757-1759. The granite was dovetailed into the solid rock, and each block into its neighbors. As the rock in which this tower was built became undermined and greatly weakened by the action of the waves, the foundation of another was laid on a different part of the reef in 1879. Its light is visible in clear weather at a distance of 17 and one half miles."—(Charles Leonard-Stuart, 1911)

"Tuberose (Polianthus) is a genus of plants of the natural order Liliace&aelig;. The plant is in high esteem for the beauty and fragrance of its flowers, the odor of which is most powerful after sunset. The fading flowers emit, in certain states of the atmosphere, an electric light and sparks. The native country of the tuberose is Mexico. They are very extensively grown by American and British florists, who, by planting the roots successionally, manage to keep up a supply of flowers at all seasons. There are several varieties."&mdash;(Charles Leonard-Stuart, 1911)

"Turtle is, in zoology, the popular name for any species of the Cheloniid&aelig;. They may be distinguished by their long, compressed, fin-shaped, non-retractile feet, with the toes inclosed in a common skin, from which only one or two claws project. The carapace is broad and much depressed, so that when these animals are on shore, and are turned over on their backs, they cannot regain the natural position. Turtles are marine animals; their pinnate feet and light shell render them excellent swimmers. They sometimes live at a great distance from land, to which they periodically return to deposit their soft-shelled eggs in the sand."&mdash;(Charles Leonard-Stuart, 1911)

"The Jacana is a wading bird; a genus of grallatores. They are very light birds; and the wide surface over which their toes extend enables them the more easily to procure their food, consisting of worms, small fishes, and insects, by walking on the leaves of aquatic plants which float on the water. Various species of the jacana are spread over the tropical regions."&mdash;(Charles Leonard-Stuart, 1911)

"The earliest account of lake dwellings is to be found in Herodotus, who describes a Thracian tribe living, in 520 B.C., in a small mountain lake of what is now Rumelia. The custom of constructing these habitations has come down to the present day. The fisherman of Lake Prasias, near Salonica, still inhabit wooden cottages built over the water, as the Thracian tribes did, and in the East Indies the practice of building lake settlements is very common. The lake dwellings proper of Switzerland came to light during the winter months of 1853-1854, when the water of the lakes fell much below its ordinary level. Dr. Keller, who first described these lake dwellings, says that the main platform was made of round timbers, rarely of split boards, covered with a bed of mud; the walls and sides were in great measure of interlaced branches, the interstices filled with moss, and daubed with clay. In his opinion, all the evidence goes to show they were rectangular in shape. It is probable that the huts were thatched, and the parts used as dormitories strewn with straw or hay."&mdash;(Charles Leonard-Stuart, 1911)

The Seventeen Year Locust (Cicada septendecim) spends seventeen years underground feeding on the roots of trees. On the seventeenth year of its life it burrows out of the ground, cracks its shell and spreads its previously unused wings. It flies to the nearest tree to mate. The female cuts holes in the branches of the tree to deposit her eggs. The males make a very loud drumming noise while they are above ground.

"The Taj Mahal, or Mehal, ('Gem of Buildings'), is a famous mausoleum, erected at Agra, India, by Shah Jehan for his favorite wife. It is 186 feet square with the corners cut off, and consists of two tiers of arches, with a single-arched porch in the middle of each side, the whole surmounted by a dome 58 feet in diameter and about 210 feet in height, flanked by four octagonal kiosks. The interior is divided into four domed chambers in the corners, and a large central arcaded octagon, all connecting by corridors. The central octagon contains two cenotaphs surrounded by a very noticeable openwork marble rail. The only light admitted enters through the delicately pierced marble screens of the windows. The decoration is especially noticeable for the stone mosaics of flower themes and arabesques, much of them in agate, jasper, and bloodstone. The entire structure stands on a white marble platform 18 feet high and 313 feet square, with tapering cylindrical minarets 133 feet high at the corners."&mdash;(Charles Leonard-Stuart, 1911)

"The Atwood machine consists of a wheel or pulley, R, over the grooved edge of which are balanced two equal weights suspended by a long silk thread which is both light and strong. The axle of this wheel is preferably supported upon the circumfrences of four friction wheels, r, r, r', r', for greater delicacy of motion. As the thread is so light that its weight may be disregarded, it is evident that the weights will be in equilibrium whatever their position." &mdash; Avery, 1895
