Polishing Apples

A young man asked an old rich man how he made his money.
The old guy fingered his expensive wool vest and said, "Well, son, it was 1932. The depth of the Great Depression. I was down to my last nickel."
"I invested that nickel in an apple. I spent the entire day polishing the apple and, at the end of the day, I sold the apple for ten cents."
"The next morning, I invested those ten cents in two apples. I spent the entire day polishing them and sold them at 5:00 pm for 20 cents. I continued this system for a month, by the end of which I'd accumulated a fortune of $9.80."
"Then my wife's father died and left us two million dollars."

East River Gas Tunnel

In 1892, the East River Gas Tunnel became the first completed tunnel under the East River, New York City, after two years' work. The connection was made between bores started from Long Island (26 Jun 1892) and on the New York side (10 Jul 1892). The Brooklyn Bridge over that river, opened 24 May 1883, took 13 years to build. The 2550-ft tunnel was designed to carry gas mains, not public traffic, and was built relatively smaller: 8½-ft high by 10½-ft wide. While finish work was done in the tunnel, a gas main was laid that first delivered gas on 15 Oct 1894. Illuminating gas from works on Long Island could then be distributed through Manhattan. The tunnelling success also provided practical knowledge enabling more tunnels under the East River. Work on four railroad tunnels commenced in 1904.«
