for thr lab I chose to compare to the alton encyclopedia documents.
off of a brief skim I assume both texts will likely mention the town and the river quite a bit.
after processing the corpus, I found that indeed both mentioned the name Alton and the river quite a bit. Additionally the both mention Saint Louis and the Mississippi River by name.
something interesting is that the 1906 version has on average 1 more word per sentence, maybe some indication of a move toward more elegant language compared to the earlier text.
