Toward the end of 1912, he traveled with Picabia, Apollinaire and Gabrielle Buffet-Picabia through the Jura mountains, an adventure that Buffet-Picabia described as one of their "forays of demoralization, which were also forays of witticism and clownery ... the disintegration of the concept of art".
Sidst på 1912 rejste han med Picabia, Apollinaire og Gabrielle Buffet-Picabia i Jurabjergene, en oplevelse Buffet-Picabia beskrev som et af deres "strejftog af demoralisering, som også var strejftog af vittigheder og klovnerier (…) desintegrationen af begrebet kunst."
