Here are some one liners...
The Chinese are Massacred -- White miners beating up and killing Chinese miners in Wyoming. It's really bad.
Pasteur and the Rabies Vaccine -- French doctors saving lives. That's good. I talk about how these guys would be arrested today.
In Other News -- Bicycle playing cards, the popcorn machine and Dr. Pepper.
The Chinese are MassacredChinese miners have done reasonably well financially in the USA and Australia. They are not getting wildly rich, but they are supporting themselves. They work hard, and they work for less money. In Wyoming, the trouble starts when the Knights of Labor (an early labor union) initiates a miners strike against Union Pacific Coal. After 2 weeks, the company replaces the white workers with Chinese. The Chinese population in Rock Springs, Wyoming soars but after the passage of the Chinese Immigration Exclusion Act the local chapter of the Knights of Labor want the Chinese booted out of town because they are driving down wages. (To be fair, everyone's wages are pretty low.) Several white miners arrive at pit number 6 and tell the Chinese miners to move off. A fight ensues and one Chinese miner is killed. A work stoppage begins and by that afternoon, 150 white men are marching on Chinatown. Shots are fired and the Chinese attempt to flee. Chinese people are beaten, robbed, shot and burned inside their homes. Troops are called in and when the Chinese are escorted back to town a week later, bodies remain out in the open eaten by dogs. The property damage alone reaches almost 4 million in 2015 dollars and no one is prosecuted since (according to the Grand Jury) no witnesses saw anyone commit any crime. The Federal government will make restitution for the property damage... eventually.   
Pasteur and the Rabies VaccineI'm not a doctor but rabies is usually caught when you are bitten by an animal that is carrying the disease. The animal seems crazed and often furious. This is when a bite can occur. As the disease progresses there is a need for water, but the patient seems fearful of any water you might offer him. (Due to muscle spasms in the throat, they often fear choking.) Thus rabies is also called "hydrophobia" which means "fear of water". Prior to this year the disease is almost always fatal. In fact, some people simply kill themselves if they are bitten whether they actually present symptoms or not. That is how fearful people can be of this disease. Dr. Louis Pasteur and another French doctor administer a rabies vaccine to a nine-year-old boy who has been mauled by a rabid dog. The boy lives. Thus, there is a method for saving an individual from death from rabies. However, the vaccine must be administered BEFORE symptoms occur. Afterwards... well... the chances of survival AFTER symptoms present themselves are low even in the modern day.

- Dr. Pepper is patented. I've been to the Dr. Pepper museum in Waco, Texas. The Texas Ranger Museum is better.
