Lumberyard

Jon's working at the lumberyard, pushing a tree through the buzz saw, and accidentally shears off all ten of his fingers. He goes to the emergency room.
The doctor says, "Yuck! Well, give me the fingers, and I'll see what I can do."
Jon says, "I haven't got the fingers."
The doctor says, "What do you mean, you haven't got the fingers? It's 1999. We've got microsurgery and all kinds of incredible techniques. I could have put them back on and made you like new. Why didn't you bring the fingers?"
Jon says, "Well, sh*t, Doc, I couldn't pick 'em up."

Steel manufacture

In 1857, Robert Mushet, an English metallurgist, received a U.S. patent for a method of manufacturing steel which improved the Bessemer process for making steel that would be more malleable. (No. 17,389). His process added manganese in the form of spiegeleisen, an alloy of iron and manganese derived from a Prussian iron ore consisting essentially of a double carbonate of iron and manganese. The softness or hardness of the steel could be regulated by diminishing or increasing the proportion of the triple compound of iron, carbon and manganese. He chose to use the alloy of the Prussian ore because it was more free of sulphur, phosphorus and silicon. Mushet also discovered tungsten steel, an alloy with about 8% tungsten.
