When China Ruled the Seas by Louise Levathes

Levathes, a former staff writer for National Geographic tells the story of seven epic voyages (1405-1433) made by unique junk armadas during the reign of the Chinese emperor Zhu Di. These "treasure ships" under the command of the eunuch admiral Zheng He traded in porcelain, silk, lacquerware and fine-art objects; they sailed from Korea and Japan throughout the Malay archipelago and India to East Africa, and possibly as far away as Australia.

WSJ: The paramount scandal of Social Security is not its insolvency but rather its abysmally low rate of return for new workers.

The Payroll Tax Trap
The Wall Street Journal
December 27, 2006; Page A8

Even if the payroll tax were left alone and all promised benefits were eventually paid out to young workers, these workers would get a tiny real annual rate of return of 1% to 1.5% on average, according to a Cato Institute analysis. Even a risk-free government bond pays 3% to 4%.

Taking personal accounts off the table eliminates the only option that will provide a better rate of return for future generations. As the nearby chart shows, personal accounts earning market returns would provide roughly twice as high an annual benefit to low income workers upon retirement, three times as high a benefit for middle income workers, and four times more to those with an income in today's dollars of $94,200 a year.

The last 10 miles of Tonawanda Creek are Erie Canal waters. Did you know the creek can flow backwards in that area during the summer?

"During the canal operational period (generally the first week of May through the last week of October) when the guard lock gate in Lockport is opened, flow in the creek often moves in an upstream (easterly) direction because the level of the Erie (Barge) Canal at Lockport is lower than that of the Niagara River at the City of Tonawanda. Up to 1100 cfs of flow are diverted from the Niagara River for canal operations."
