Going to phone someone to come and rescue you?
The phone wasn't invented until 1876, by Alexander Graham Bell in Scotland, of course.
Is it starting to rain where you are in the meadow? Anyone got an umbrella?
Well, maybe yes, although you probably want the modern umbrella invented in 1852 by Samuel Fox. He invented the lighter version made with fine steel wire for its ribs. Before then, whalebone was predominantly used, creating a heavy and awkward umbrella.
How about using a ballpoint pen to scribble a rescue letter to someone back home in the 21st century?
Not until 1884, anyway. So just keep dipping that pen's tip into ink after each few words you write, assuming, of course, you carry an inkwell with you when you're lost in a meadow.
How about flagging down a car that will at least get you back into town?
Okay, have you found your way into town? Did it take you a long time? Is it dark? Want to turn on a light?
It wasn't until 1879 when Thomas Edison discovered that a carbon filament in an oxygen-free bulb glowed.
And now you know.
