During that time Paul became acquainted with the ex-President of Peru, Don Nicholas de Pierola, then in banishment.

They became fast friends, the ex-President taking much interest in torpedo work, and they frequently made quiet experiments at isolated places down the river.

Before they separated he assured Paul that if he ever regained his position in Peru, he would remember their pleasant times aboard the "Paul Boyton," and their torpedo experiments.
August 12th, Paul began a voyage down the Seine from Nogent-sur-Seine to Paris, a distance of two hundred miles, which he accomplished in four days, landing at the Exposition buildings, Champs de Mars, before an immense concourse of people.

The crowds that lined the banks of the Seine were estimated at half a million by the Figaro.

As he passed under Pont Neuf he stood up and dipped the stars and stripes in salute.
