I'm trying to translate this sentence - "L'Exposition coloniale, dont s'occupe Jules Charles Roux, étage ses vingt-neuf pavillons au Trocadéro." I don't understand what 'étage' is supposed to mean here. Any ideas? The closest I've got to translating it is: The colonial Exposition, lead by Julius Charles Reddish, floor/ stage his twenty nine houses to the Trocadero. This makes no sense at all!
