Explanation:

The last line says, "Nought may endure but Mutability", which means, in simpler words, that nothing else lasts, only change lasts. That line summarizes the theme of the whole poem. "Mutability" is a four-stanza poem by Percy Bisshe Shelley that describes life and its experiences as fleeting. We, our thoughts, our actions, our cares, our days, they are all going to pass. Attachment is almost foolish since nothing will stay the same, our yesterday and our tomorrow are never alike. The only certainty we have is that change is eternal. It is the only thing that endures, and it touches every single aspect of our lives.

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
