A mysterious building had been erected on the outskirts of a small town. It was shrouded in mystery. All that was known about it was that it was a chemical laboratory. An old farmer, driving past the place after work had been started, and seeing a man in the doorway, called to him:
"What be ye doin' in this place?"
"We are searching for a universal solvent—something that will dissolve all things," said the chemist.
"What good will thet be?"
"Imagine, sir! It will dissolve all things. If we want a solution of iron, glass, gold—anything, all that we have to do is to drop it in this solution."
"Fine," said the farmer, "fine! What be ye goin' to keep it in?"
