I te tau 1893, i tonoa a Lewis e te Pennsylvania Forestry Commission ki te peita i tētahi huinga o ngā pikitia 50 o ngā rau o ngā rākau hei whakaatu ki te World's Columbian Exposition i Chicago. I whakaarohia te mahi a Lewis hei angitu, i riro i a ia he mētara me tetahi tohu, a, i whakaatuhia ano te huinga peita ki te iwi i te Whakaaturanga Pan-American o 1901 i Buffalo, New York, me te 1904 Louisiana Purchase Exposition
i St. Louis.
