With all respect, I am not being snarky here: "What" was brought back to entice visitors? `Olelo Hawai`i?
You are surely not suggesting that our wonderful immersion schools, Hawaiian focused cultural education programs, and `Aha Punana Leo are HTA tools, are you?
And for clarity, ALL languages that were NOT English were prohibited in SCHOOLS in 1896, not just Hawaiian--and that was only in SCHOOLS, not among families or in public.
To say that "speaking" Hawaiian was "outlawed" is very misleading.
