A trip hammer resembles a hand-hammer held in a horizontal position. The hammer is placed at the end of a heavy beam pivoted near the opposite end. By means of simple machinery the handle was raised and then "tripped" or let fall, when the hammer-head delivered its blow upon the anvil. They were at first operated by water power, but later by steam power.

A planer is a type of metalworking machine tool that is analogous to a shaper, but larger, and with the entire workpiece moving beneath the cutter, instead of the cutter moving above a stationary workpiece. The work table is moved back and forth on the bed beneath the cutting head either by mechanical means, such as a rack and pinion gear, or by a hydraulic cylinder.

Chattanooga, "the Scenic City", is the fourth-largest city in Tennessee (after Memphis, Nashville, and Knoxville), and the seat of Hamilton County, in the United States of America. It is located in southeast Tennessee on Chickamauga and Nickajack Lake, which are both part of the Tennessee River. The city, which lies at the transition between the ridge-and-valley portion of the Appalachian Mountains and the Cumberland Plateau, is surrounded by mountains and ridges. The first inhabitants of the Chattanooga area were Native American Indians with sites dating back to the Upper Paleolithic period, showing continuous occupation through the Archaic, Woodland, Mississippian (900–1650 AD), Muskogean and Cherokee (1776 – 1838 AD) periods.

Newspapers and speakers especially condemned the "land embargo" — the cutting-off trade with Canada. The trade so suddenly thrown into confusion by it was represented in a caricature by a bewildered serpent which had been suddenly stopped in its movements by two trees, marked, respectively, "Embargo" and "Non-Importation Act." The wondering snake is puzzled to know what has happened, and the head cries out, "What's the matter, tail?" The latter answers, "I can't get out." A cock, representing France, stands by, joyfully.

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

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.

The family Elateridae is commony called click beetles (or "typical click beetles" to distinguish them form the related Cerophytidae and Eucnemidae), elaters, snapping beetles, spring beetles or "skipjacks". They are a cosmopolitan beetle family characterized by the unusual click mechanism they possess. There are a few closely-related families in which a few members have the same mechanism, but all elaterids can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent "click" which can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself. There are about 7000 known species.

The Bobolink, Dolichonyx oryzivorus, is a small New World blackbird and the only member of genus Dolichonyx. Adults are 16-18 cm long with short finch-like bills. Adult males are mostly black, although they do display creamy napes, and white scapulars, lower backs and rumps. Adult females are mostly light brown, although their coloring includes black streaks on the back and flanks, and dark stripes on the head; their wings and tails are darker. Their breeding habitats are open grassy fields, especially hay fields, across North America. In high-quality habitats, males are often polygynous. Females lays 5 to 6 eggs in a cup-shaped nest, which is always situated on the ground and is usually well-hidden in dense vegetation. Both parents feed the young.

The Dromedary camel (Camelus dromedarius) is a large even-toed ungulate. It is often referred to as the one-humped camel, Arabian camel, or simply as the "dromedary". Its native range is unclear, but it was probably the Arabian Peninsula. The domesticated form occurs widely in northern Africa and the Middle East; the world's only population of dromedaries exhibiting wild behaviour is an introduced feral population in Australia. The dromedary camel is arguably the best-known member of the camel family. Other members of the camel family include the llama and the alpaca in South America. The Dromedary has one hump on its back, in contrast to the Bactrian camel which has two. A good mnemonic for remembering which way around these terms apply is this: "Bactrian" begins with "B", and "Dromedary" begins with "D"; "B" on its side has two humps, whilst "D" on its side has only one hump.

The Bactrian Camel (Camelus bactrianus) is a large even-toed ungulate native to the steppes of north eastern Asia. It is one of the two surviving species of camel. The Bactrian Camel has two humps on its back, in contrast to the single-humped Dromedary Camel. Nearly all of the estimated 1.4 million Bactrian Camels alive today are domesticated, but in October 2002 the estimated 950 remaining in the wild in northwest China and Mongolia were placed on the critically endangered species list.

The Anabantidae are a family of perciform fish commonly called the climbing gouramies or climbing perches. As labyrinth fishes, they possess a labyrinth organ, a structure in the fish's head which allows them to breathe atmospheric oxygen.

Cobras are venomous snakes of the familys Elapidae, of several genera, but particularly Naja. (Non-cobra elapidae include the taipans, brown snakes, tiger snakes, fierce snakes, coral snakes, mambas and sea snakes.) Cobras generally inhabit tropical and desert regions of Asia and Africa. When feeling threatened, cobras can rear up and flatten their heads into an instantly recognisable warning posture. The rest of the time their heads are symmetrical and they look much like any other snake bites.

Cranes are large, long-legged and long-necked birds of the order Gruiformes, and family Gruidae. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. There are representatives of this group on all the continents except Antarctica and South America. Most species of cranes are at least threatened, if not critically endangered, within their range. The plight of the Whooping Cranes of North America inspired some of the first US legislation to protect endangered species.
