Dog playing piano

It is World Piano Day!

A man walks into a bar with a small dog under his arm and sits down at the counter, placing the dog on the stool next to him. The bartender says, "Sorry, pal. No dogs allowed."
The man says, "But this is a special dog – he plays the piano!"
The bartender replies, "Well, if he can play that piano, you both can stay... and have a drink on the house!"
So the man puts the dog on the piano stool, and the dog starts playing. Ragtime, Mozart... and then he plays some rock 'n' roll. The bartender and patrons are amazed.
Suddenly, a bigger dog runs in, grabs the small dog by the scruff of the neck, and drags him out. The bartender asks the man, "What was that all about?"
The man replies, "Oh, that was his mother. She wanted him to be a doctor."

First steam engine in US

In 1753, the first steam engine imported into the American colonies landed at New York City on the S.S. Irene, which left London on 6 Jun 1753. It was installed to pump water from a copper mine owned by Col. John Schuyler in New Barbadoes Neck (now North Arlington), New Jersey. It arrived there on 25 Sep 1753, was erected, and in operation on 12 Mar 1755. Josiah Hornblower, 25, who came with it from England, superintended the engine, becoming America's first steam engineer. Arent Schuyler, who had owned a large tract of land since 1695, started the copper mine after a slave turned up green copper ore while plowing. He exported the ore to England. His son John later took over managing the mine after his death.*«[Image: Schematic of the Newcomen engine, or atmospheric engine, of the period which was already in use in the tin mines of Cornwall.
