Silicon Valley of India: The Silicon Valley of India is a nickname of the Indian city of Bangalore.

Postal history of Oregon: The postal history of Oregon began in 1847, a year before the Oregon Territory was established, when the United States Post Office contracted delivery of postal items from the east coast of the United States to west coast locations via Panama.

It was not until 1849 that the Pacific Mail Steamship Company opened routes from Panama along the west coast.  The earliest postmarked items from the offices in Astoria and Oregon City were in 1849.
