17-year-old Helena Muffly wrote exactly 100 years ago today:
Wednesday, April 3, 1912: Ma went to Milton today. I got her to get me a compass. We have arrived at constructing things in geometry. We have exams on Monday, so I’ve prepared in one way.

Her middle-aged granddaughter’s comments 100 years later:
I can’t picture what compasses looked prior to the development of plastic. Were they made of wood? I wish that I’d scoped out the flea market prior to writing this post so I could describe ones from a hundred years ago.
Grandma probably also used a ruler to construct triangles, squares, and other shapes—perhaps one with a business advertisement on it. The Milton Historical Society has an old ruler from the Bijou Dream Theater. Grandma mentioned attending silent films at that theater several times in the diary, so maybe, just maybe —and I’m letting my imagination run wild–she used a Bijou Dream ruler to “construct things.”
