Another Compromise on SlaveryWith California demanding to join the Union as a free state, a new slavery compromise is needed to keep the Southern states from seceding from the Union. After the Mexican-American War the USA acquired new territories. If the Missouri Compromise was to be followed then California and Texas should be split into North and South since they both straddle the parallel line of 36 degrees 30 minutes North which is the dividing line between slave and free states. California wants to join as a whole state, and with the ongoing gold rush, money talks. There is also a border dispute between Texas and the New Mexico territory. Daniel Webster makes his famous appeal to the moderates of the North and South and Henry Clay pushes a series of resolutions to reduce the size of Texas to its modern day borders in exchange for taking over Texas debt. The slavery question in the territories is left to the voters to decide, which will lead to bloody fights in the future between the new and old settlers on the question of slavery. Slave trading in Washington DC is abolished although slavery itself is not, and the Fugitive Slave Act is strengthened. With these compromises, war is averted, but only for a few years. When Kansas and Nebraska gear up to join the Union, the stuff will hit the fan again. This issue is not going away.  
The Underground Railroad is Still RunningWith the passing of a stricter Fugitive Slave Law, special commissions are set up that do not allow a fugitive to testify on his own behalf. No trial by jury is allowed. Penalties are assessed upon law officers who refuse to enforce the fugitive slave laws. The commissioner of these pseudo-courts is paid twice as much to rule against the fugitive than he is to rule on the fugitive's behalf. When this new law is challenged in various state courts it is often overturned, but the Supreme Court will uphold the practice. This new law is agitating the abolitionists so they step up their efforts to help slaves escape to free states and Canada. It is called the Underground Railroad, but it is actually any number of escape routes by road, or wagon, boat. Whatever it takes. Safe-houses along the way feed and house runaways until they can move on. One runaway slave is Harriet Tubman. She has been guiding slaves along the Underground Railroad over and over again, but with this new Fugitive Slave law she is extending the trip into Canada now. By all accounts Harriet Tubman is a making a difference, and in total she will guide about 70 runaway slaves to freedom. In the next ten years the use of the Underground will soar. That means a lot more people than Harriet will be breaking this law.   
Yet Another Arctic Rescue MissionLady Franklin has asked for help to find her husband, Rear-Admiral Sir John Franklin of the British Royal Navy. He was last seen on his mission to chart the Northwest Passage. He left with two ships, specially equipped with engines that not only propelled the ships but kept the men warm in the cold weather. They left with food for 3 years so it is possible they are still alive. The McClure Expedition is organized to look for Sir Franklin. The USS Advance also sets out to find him but both efforts will be fruitless. In a few years Dr. John Rae will ask some Inuit hunters about Sir Franklin and they will report that he and his crew left their ships and died of starvation on the ice. Apparently, they also resorted to cannibalism and when this report reaches Lady Franklin she will denounce Dr. Rea and so will most other people. Sir Franklin is considered a hero and he would never do anything so ignoble as eating his crew. Would he? (Actually, he can't. He is already dead, but don't tell Lady Franklin.)
