I will be in New York City tomorrow and for the next few days.
In honor of that, let me offer up a free read from "Rats: Observations on the History & Habitat of the City's Most Unwanted Inhabitants" by Robert Sullivan.
This is a book about the rats of New York City, including profiles of rat catchers, rat biology, rat history, and other odd bits. A good read, if not quite a complete history of one the world's most important animals.
The first two chapters of the book can be read & here. This is a 12-page PDF.
Order the book new from amazon.com here, or from www.abebooks.com if you are looking for a used edition.
