I was out walking with my 4 ye...

I was out walking with my 4 year old daughter. She picked up something off the ground and started to put it in her mouth. I took the item away from her and I asked her not to do that.

"Why?" my daughter asked.

"Because it's been laying outside, you don't know where it's been, it's dirty and probably has germs" I replied.

At this point, my daughter looked at me with total admiration and asked, "Wow! How do you know all this stuff?"

"Uh," I was thinking quickly, "All moms know this stuff. It's on the Mommy Test. You have to know it, or they don't let you be a Mommy." We walked along in silence for 2 or 3 minutes, but she was evidently pondering this new information.

"OH...I get it!" she beamed, "So if you don't pass the test you have to be the daddy."

"Exactly" I replied back with a big smile on my face and joy in my heart.

First U.S. natural gas well

In 1815, the first developed natural gas well in the U.S. was discovered accidentally at Burning Springs during the digging of a salt brine well near Charleston, West Virginia. In the U.S., natural seepage had been observed centuries earlier in various places, but here, there was development and use of the natural gas and oil. In 1921, Fredonia, New York, the first gas well dug specifically for natural gas in the U.S. was drilled to 27 feet by gunsmith, William Hart to develop the seepage seen on the banks of Canadaway Creek. Early use was limited. The first industrial use of natural gas in the US was to evaporate brine for its salt, in 1841 by William Tompkins. Earlier, manufactured gas was first used in the U.S. for street lamps in Baltimore (1816).«
