YOUTH LOSES BOTH LEGS IN FARM MISHAP Richard Hardsog, 18 of North Brookfield Falls Into Corn Cutting Machine Ware, Sept. 17—A North Brookfield youth was reported in critical condition in Mary Lane Hospital tonight, after an accident in which both his legs were badly mutilated, and despite close co-operation between state and local police in rushing blodd plasma from Cooley Dickinson Hospital Blood Bank to the hospital here...

There's more, but it's mostly about the doctors, police, etc., not about Richard.
