This happened long before the great depression, but my grandfather used to tell the story about the ladies from the "big town" who came by train every Christmas season up the mountain to his town to give the kids presents. It was usually socks, hankies, etc. and maybe some candy and nuts.
One year, everyone got an orange. Nobody knew what to do with it. The kids brought them home and put them on the table to look at them. Do you cook them? Eat them raw? What do they taste like?
Oranges were always important to my grandpa. He made sure everyone had one in their stocking.
