During the past summer the track has been completed across this Continent, and so much sooner than was thought possible, that the difficulties overcome are apt to be underrated. Some account of a single item in the great work may therefore be interesting. Between Omaha and Sacramento there are nineteen tunnels. Four of these are on the Union Pacific, and fifteen on the Central. The latter, having been completed before those on the Union. Pacific were commenced, will be spoken of first.
