The rules, dating to the 1860s, are quirky. Underhand pitches. No called strikes. No walks, just warnings. If you catch a fly ball in the air, it's an out. If you catch it on one bounce, it's an out. Don't overrun first base unless you plan on running back to the bag. Foul territory isn't a safe haven.

Even the "E" in Essex Base Ball Club was vintage.
