Boing Boing is linking to a vermonter.com post today about a New Haven, Vermont grave site that, by order of its occupant (prior to his death, one assumes), was fitted with a breathing tube and a window. The grave's occupant, one Timothy Clrk Smith, died on Halloween in 1893 and was apparently terrified of the possibility of being buried alive, hence the grave's unusual added features. According to vermonter.com...
His body was interred at the Evergreen Cemetery in New Haven, VT. in a specially prepared grave. Beneath the odd, grassy mound of earth, Timothy's face was positioned beneath a cement tube that led to the surface. The 6 foot tube ended at a piece of 14x14 inch plate glass allowing Tim to gaze upward in the event that he was buried alive. A bell was placed in his hand just in case he needed to signal that he was still alive.
The grave is in Evergreen Cemetary on Town Hill Road in New Haven (just a few miles north of Middlebury on Rt. 7).
