Australia will colonize the islands to its north and connect by some isthmian umbilicus to Asia.

Nevertheless, long before roads were built in the isthmian region collectors and biologists visited it, especially the town of Tehuantepec, from which collections date back to the 1870's.

At several other times, such as the late Ordovician and mid-Devonian, when the isthmian barrier existed, it probably turned an important current northward into what is now the Mississippi Basin instead of into the Atlantic.

We favor the construction, ownership, control, and protection of an isthmian canal by the government of the United States.

At Panama, a vessel can pass through the canal in half a day, or, reckoning other causes of detention, coaling, etc., the total isthmian transit should not take more than one day.
