PROBLEM: Context: The film opens with narration over a silhouette of Hill House at night. The narrator, Dr. John Markway (Richard Johnson) tells us, "An evil old house, the kind some people call haunted is like an undiscovered country waiting to be explored. Hill House had stood for 90 years and might stand for 90 more. Silence lay steadily against the wood and stone of Hill House. Whatever walked there walked alone." Title and credits follow, then narration continues, "Scandal, murder, insanity, suicide: The history of Hill House was ideal. It had everything I wanted..." The house was built in New England by a man named Hugh Crain for his wife and young daughter. A horse and carriage accident took the life of the first Mrs. Crain (an uncredited Pamela Buckley) before she even saw the house. Hugh Crain (an uncredited Howard Lang) and young daughter, Abigail (an uncredited Janet Mansell) said a few words over the body, but Hugh was left an embittered man. Crain married again, and the second Mrs. Crain (an uncredited Freda Knorr) also died, falling down the main staircase. Hugh Crain left Abigail with a nurse (an uncredited Susan Richards) and went to England where he died in a drowning accident. Abigail kept the same nursery room her entire life. By the time she was eighty (an uncredited Amy Dalby) she was a bedridden invalid. Her nurse-companion (an uncredited Rosemary Dorken) was a local girl and, it is with this young companion the evil reputation of Hill House really begins. The old lady died while calling for help. The companion was trysting on the verandah with a farm hand. The companion inherited Hill House and occupied it for many years, but eventually hanged herself. The house then passed to a distant relative, named Mrs. Sanderson (Fay Compton).Markway visits Mrs. Sanderson where he convinces her to let him use the house for psychic research. He explains, "I shall occupy the house with a group of carefully selected assistants...I must have specially qualified help to take notes and document any evidence of the supernatural I may find." Eldridge Harper (Ronald Adam), Mrs. Sanderson's lawyer, voices his concern about publicity seekers and the propriety of having women in the house. Harper suggests to Mrs. Sanderson that her nephew, Luke, joins the doctor at Hill House, as he expects to inherit the property. Mrs. Sanderson asks point blank, "Exactly what do you and your assistants expect to find at Hill House?" Markway replies, "Maybe only a few loose floorboards, and maybe, I only say maybe, the key to another world."Dr. Markway, taking a leave of absence from his university professorship, finalizes his list of assistants. Only two end up accepting, Eleanor Lance and Theodora (no last name).Eleanor Lance (Julie Harris) is living with her sister. She is nearly broke and weary after looking after her invalid mother non-stop for eleven years. Mother is now dead, and she fights with her sister over just about everything. She begs to use the car, which is after all, half hers. Her brother-in-law, Bud Fredericks (an uncredited Paul Maxwell) tries to act as mediator between Eleanor and his wife, Carrie (Diane Clare). He is sympathetic to Eleanor's plight, but their daughter, Dora (an uncredited Verina Greenlaw) takes her cues from her mother, and taunts her Aunt Eleanor. On the vacation plan, Bud sides with Eleanor, "I think you should have a vacation, Nell." Carrie objects, but Eleanor is not to be deterred and she shows her family how she reacts when pushed to her breaking point. She is normally quiet and meek, but when pushed is loud and assertive.Nell decides to take the car and confronts the garage attendant (an uncredited Claude Jones) for the keys. She departs Boston along U.S. 50 and Route 238 to Hill House. We hear Nell thinking and she reveals she will never return to live with her sister. In fact, most of what we learn of Eleanor is hearing her thoughts.Eleanor

PROBLEM: Context: A volcano is a vent through which molten rock and gas escape from a magma chamber. Volcanoes differ in many features, such as height, shape, and slope steepness. Some volcanoes are tall cones and others are just cracks in the ground (Figure 1.1). As you might expect, the shape of a volcano is related to the composition of its magma. Composite volcanoes are constructed of felsic to intermediate rock. The viscosity of the lava means that eruptions at these volcanoes are often explosive. Viscous lava cannot travel far down the sides of the volcano before it solidifies, which creates the steep slopes of a composite volcano. In some eruptions the pressure builds up so much that the material explodes as ash and small rocks. The volcano is constructed layer by layer, as ash and lava solidify, one upon the other (Figure 1.3). The result is the classic cone shape of composite volcanoes. Mount St. Helens was a beautiful, classic, cone-shaped volcano. In May 1980 the volcano blew its top off in an explosive eruption, losing 1,300 feet off its summit. Mt. Fuji in Japan is one of the worlds most easily recognized composite volca- noes. Shield volcanoes get their name from their shape. Although shield volcanoes are not steep, they may be very large. Shield volcanoes are common at spreading centers or intraplate hot spots (Figure 1.4). Hawaii has some spectacular shield volcanoes including Mauna Kea, which is the largest mountain on Earth from base to top. The mountain stands 33,500 ft high, about 4,000 feet greater than the tallest mountain above sea level, Mt. Everest. A cross section of a composite volcano reveals alternating layers of rock and ash: (1) magma chamber, (2) bedrock, (3) pipe, (4) ash layers, (5) lava layers, (6) lava flow, (7) vent, (8) lava, (9) ash cloud. Frequently there is a large crater at the top from the last eruption. Mauna Kea on the Big Island of Hawaii is a classic shield volcano. The lava that creates shield volcanoes is fluid and flows easily. The spreading lava creates the shield shape. Shield volcanoes are built by many layers over time and the layers are usually of very similar composition. The low viscosity also means that shield eruptions are non-explosive. Cinder cones are the most common type of volcano. A cinder cone has a cone shape, but is much smaller than a composite volcano. Cinder cones rarely reach 300 meters in height, but they have steep sides. Cinder cones grow rapidly, usually from a single eruption cycle. These volcanoes usually flank shield or composite volcanoes. Many cinder cones are found in Hawaii. A lava fountain erupts from Puu Oo, a cinder cone on Kilauea. Cinder cones are composed of small fragments of rock, such as pumice, piled on top of one another. The rock shoots up in the air and doesnt fall far from the vent. The exact composition of a cinder cone depends on the composition of the lava ejected from the volcano. Cinder cones usually have a crater at the summit. Most cinder cones are active only for a single eruption. Click image to the left or use the URL below. URL:
