On the first day of school...

On the first day of school, Peter handed his new teacher a note from his mother. The teacher unsealed the note, read it, looked at Peter with a frown, and placed the note inside a desk drawer. “So what did she write?” Peter asked. “It’s a disclaimer.”
“A what?” “It says, ‘ The opinions expressed by Peter are not necessarily those of his mother or father,’”

Natural gas illumination

In 1825, the first time natural gas was used for illumination was in Fredonia, in western N.Y. A pipeline was laid from a well to a residence where a reception was held for General Lafayette. The house was brightly illuminated by natural gas, using about 30 burners. This was regarded as a great curiosity. Fredonia residents had seen bubbles of gas rising from a creek in 1821. When a gunsmith, William Hart ("father of natural gas") heard reports of this "creek that burned," he dug the first U.S. natural gas well on the bank of the creek, and covered it to accumulate the gas. A 1825 newspaper article reported that natural gas from this well was being used to light the lamps of two stores, two shops and a grist mill near the creek.
