Mailing May by Michael O. Tunnell, 1997.

Four-year-old Charlotte May lives in a small town in Idaho in 1914. May, as her family calls her, wants to visit her grandmother in another town, but travel during this time is difficult and expensive. With a lack of roads that are easy to travel, the only comfortable way to get to May’s grandmother’s town is by train. Unfortunately, May’s family can’t afford to buy a train ticket for her.

May wants so badly to go see her grandmother that she even asks at the local general store if the owner can hire her, but he doesn’t have any work that a little girl could do.  Then, May’s mother’s cousin helps the family to find a more affordable alternative. If May can’t travel as a passenger, is it possible for her to travel as . . . mail?

It turns out that the rate for mailing a live package the size of May is much cheaper than the fee for a passenger ticket.  Because May’s mother’s cousin works in the mail car on the train, he could take responsibility for her during the trip.  So, with a label on her clothes, declaring her to be “baby chicks” and the proper postage stuck to her jacket, May undertakes the journey to her unsuspecting grandmother’s house.

This story was based on a real incident. In fact, May wasn’t the only child to be sent through the mail when their parents couldn’t afford to send them as passengers. I also like the book for its glimpse at travel and mail services over 100 years ago.
