Finally, it was determined that fleas on rats caused the black death, but that wasn’t until the global outbreak that happened more recently, in China, 1855 which was later declared as ended, in 1959, that we knew what actually happened. Scientists and specialists that studied the case determined that rats were one of the reasons for the spread of the disease. They achieved this by noticing that many rats were carrying symptoms of the plague that were similar to those that people were having. By realizing that many victims had flea bites, they eventually found out that the rat fleas were the ones carrying the disease.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
