Insomnia Collection Vol. 006 by Various

Drift off to dreamland with excerpts from this vintage collection of books about mechanical and engineering topics. You’ll be sure to snooze to topics like scaffolding, railroad construction, and the uses of the lathe. If you are inherently interested in any of these topics, I apologize. I will read them in a soft, soothing voice that will try to make them as boring as possible. - Summary by Verla Viera
