The fluctuations in Mining shares in the earlier periods
Of mining specuatons Is curious. In the early part or
the Summer 1852 the Ophr ground In Nevada could be
bought for $780, and the Gould Curry for ~ per foot
In less than eight months the former had risen 70 $1,000
per foot aud the latter TO $500 per foot In less than two
years from that time the Gould Curry was selling at
