Chinese Business Trip

A man went on a business trip to China and wanted to buy some gifts for his kids. He went to a shop and found a nice looking CD player. Wary of buying inferior goods, he asked the shopkeeper, 'What would happened if this does not work?'
The shopkeeper quietly points to the only sign in English that reads, 'GUARANTEE NO SPOILT'.
Feeling assured, he paid for the CD player and returns to his hotel. He tried to use the CD player after returning to the hotel but it would not even switch on.
He quickly return to the shop and asked for a refund or an exchange for another unit. When the shopkeeper refused to give either, the man points to the sign assuring him of a guarantee.
The shopkeeper then said, 'Brother, you are in China. We read from the right to the left.'

Canvass White

Died 18 Dec 1834 at age 44 (born 8 Sep 1790). American civil engineer assisted Benjamin Wrightin the construction of the Erie Canal from 1816. To prepare for building the canal, in late 1817, White travelled extensively in Great Britain visiting canals and learning construction methods. With this experience, on his return, he was Wright's principal assistant. Building locks required a hydraulic cement as mortar between the stones. Because of the high cost to import it from England, White investigated making cement from local limestone. He found rock near the canal route in Madison County was very suitable. He obtained a the first U.S. patent for waterproof cement on 1 Feb 1820. White was consulting engineer for many other canal projects, but retired young due to poor health, and died shortly after at age 44.«
