In the decade before the Civil War various north and south lines of railway were projected and some of these were assisted by grants of land from the Federal Government.

The public conviction that a railroad linking the West and the East was an absolute necessity became so pronounced after the gold discoveries of '49 that Congress passed an act in 1853 providing for a survey of several lines from the Mississippi to the Pacific.

The construction of extensive railways, however, and particularly the consolidation of small, experimental lines into large systems, dates from the days of the discovery of gold in California.

When people say Jerry Lee Lewis invented rock n' roll, they forget Little Richard. People talk about Elvis Presley and forget he was singing black music. I don't blame Elvis.
