It's cotton-pickin' time in our part of the world... these are cotton modules. After the cotton pickers harvest the cotton from the fields they drop their load into what's called the "module builder" which compresses the cotton into modules. The cotton modules are then dropped off in front of the gin, which then separates the cottonseed from the cotton fiber. That process is called "ginning", and it produces bales of cotton ready to be delivered to the various cloth manufacturers. Interesting stuff, huh?
