With walls and towers were girdled round:

And there were gardens bright with sinuous rills

Surrounding halls of vast machinery.

And all earth's products, from fine arts to pills,

Massed in that maze by that great inland sea.

Fast, from that deep romantic chasm which slanted

Through Colorado, the Grand Cañon; over

Yellowstone's marvel—teeming miles enchanted;

Far-sweeping prairies erst by redskins haunted;

Steaming and railing, like bee-swarms to clover,
