[Q]: Claude Rains and James Stewart in Mr. Smith Goes to Washington Play media Trailer James Stewart and Jean Arthur in a taxicab The governor of an unnamed western state, Hubert "Happy" Hopper (Guy Kibbee), has to pick a replacement for recently deceased U.S. Senator Sam Foley. His corrupt political boss, Jim Taylor (Edward Arnold), pressures Hopper to choose his handpicked stooge, while popular committees want a reformer, Henry Hill. The governor's children want him to select Jefferson Smith (James Stewart), the head of the Boy Rangers. Unable to make up his mind between Taylor's stooge and the reformer, Hopper decides to flip a coin. When it lands on edge and next to a newspaper story on one of Smith's accomplishments he chooses Smith, calculating that his wholesome image will please the people while his naivete will make him easy to manipulate. Junior Senator Smith is taken under the wing of the publicly esteemed, but secretly crooked, Senator Joseph Paine (Claude Rains), who was Smith's late father's friend. Smith develops an immediate attraction to the senator's daughter, Susan (Astrid Allwyn). At Senator Paine's home, Smith has a conversation with Susan, fidgeting and bumbling, entranced by the young socialite. Smith's naive and honest nature allows the unforgiving Washington press to take advantage of him, quickly tarnishing Smith's reputation with ridiculous front page pictures and headlines branding him a bumpkin. To keep Smith busy, Paine suggests he propose a bill. With the help of his secretary, Clarissa Saunders (Jean Arthur), who was the aide to Smith's predecessor and had been around Washington and politics for years, Smith comes up with a bill to authorize a federal government loan to buy some land in his home state for a national boys' camp, to be paid back by youngsters across America. Donations pour in immediately. However, the proposed campsite is already part of a dam-building graft scheme included in an appropriations bill framed by the Taylor political machine and supported by Senator Paine. Unwilling to crucify the worshipful Smith so that their graft plan will go through, Paine tells Taylor he wants out, but Taylor reminds him that Paine is in power primarily through Taylor's influence. Through Paine, the machine in his state accuses Smith of trying to profit from his bill by producing fraudulent evidence that Smith already owns the land in question. Smith is too shocked by Paine's betrayal to defend himself, and runs away. Saunders, who looked down on Smith at first, but has come to believe in him, talks him into launching a filibuster to postpone the appropriations bill and prove his innocence on the Senate floor just before the vote to expel him. In his last chance to prove his innocence, he talks non-stop for about 24 hours, reaffirming the American ideals of freedom and disclosing the true motives of the dam scheme. Yet none of the Senators are convinced. The constituents try to rally around him, but the entrenched opposition is too powerful, and all attempts are crushed. Owing to the influence of Taylor's machine, newspapers and radio stations in Smith's home state, on Taylor's orders, refuse to report what Smith has to say and even distort the facts against the senator. An effort by the Boy Rangers to spread the news in support of Smith results in vicious attacks on the children by Taylor's minions. Although all hope seems lost, the senators begin to pay attention as Smith approaches utter exhaustion. Paine has one last card up his sleeve: he brings in bins of letters and telegrams from Smith's home state, purportedly from average people demanding his expulsion. Nearly broken by the news, Smith finds a small ray of hope in a friendly smile from the President of the Senate (Harry Carey). Smith vows to press on until people believe him, but immediately collapses in a faint. Overcome with guilt, Paine leaves the Senate chamber and attempts to commit suicide, but is stopped by other senators. When he is stopped, he bursts back into the Senate chamber, loudly confessing to the whole scheme;

[Q]: Freshwater below Earths surface is called groundwater. The water infiltrates, or seeps down into, the ground from the surface. How does this happen? And where does the water go? Water infiltrates the ground because soil and rock are porous. Between the grains are pores, or tiny holes. Since water can move through this rock it is permeable. Eventually, the water reaches a layer of rock that is not porous and so is impermeable. Water stops moving downward when it reaches this layer of rock. Look at the diagram in Figure 13.11. It shows two layers of porous rock. The top layer is not saturated; it is not full of water. The next layer is saturated. The water in this layer has nowhere else to go. It cannot seep any deeper into the ground because the rock below it is impermeable. The top of the saturated rock layer in Figure 13.11 is called the water table. The water table isnt like a real table. It doesnt remain firmly in one place. Instead, it rises or falls, depending on how much water seeps down from the surface. The water table is higher when there is a lot of rain and lower when the weather is dry. An underground layer of rock that is saturated with groundwater is called an aquifer. A diagram of an aquifer is shown in Figure 13.12. Aquifers are generally found in porous rock, such as sandstone. Water infiltrates the aquifer from the surface. The water that enters the aquifer is called recharge. Most land areas have aquifers beneath them. Many aquifers are used by people for freshwater. The closer to the surface an aquifer is, the easier it is to get the water. However, an aquifer close to the surface is also more likely to become polluted. Pollutants can seep down through porous rock in recharge water. An aquifer that is used by people may not be recharged as quickly as its water is removed. The water table may lower and the aquifer may even run dry. If this happens, the ground above the aquifer may sink. This is likely to damage any homes or other structures built above the aquifer. One of the biggest aquifers in the world is the Ogallala aquifer. As you can see from Figure 13.13, this aquifer lies beneath parts of eight U.S. states. It covers a total area of 451,000 square kilometers (174,000 square miles). In some places, it is less than a meter deep. In other places, it is hundreds of meters deep. The Ogallala aquifer is an important source of freshwater in the American Midwest. This is a major farming area, and much of the water is used to irrigate crops. The water in this aquifer is being used up ten times faster than it is recharged. If this continues, what might happen to the Ogallala aquifer? The top of an aquifer may be high enough in some places to meet the surface of the ground. This often happens on a slope. The water flows out of the ground and creates a spring. A spring may be just a tiny trickle, or it may be a big gush of water. One of the largest springs in the world is Big Spring in Missouri, seen in Figure 13.14. Water flowing out of the ground at a spring may flow downhill and enter a stream. Thats what happens to the water that flows out of Big Spring in Missouri. If the water from a spring cant flow downhill, it may spread out to form a pond or lake instead. Lake George in New York State, which is pictured in Figure 13.15, is a spring-fed lake. The lake basin was carved by a glacier. Some springs have water that contains minerals. Groundwater dissolves minerals out of the rock as it seeps through the pores. The water in some springs is hot because it is heated by hot magma. Many hot springs are also mineral springs. Thats because hot water can dissolve more minerals than cold water. Grand Prismatic Spring, shown in Figure 13.16, is a hot mineral spring. Dissolved minerals give its water a bright blue color. The edge of the spring is
