Analysis of Niagara

Thou art a giant altar, where the Earth
Must needs send up her thanks to Him above
Who did create her. Nature cometh here
To lay its offerings upon thy shrine.
The morning and the evening shower down
Bright jewels, -- changeful opals, em'ralds fair.
The burning noon sends floods of molten gold,
The calm night crowns thee with its host of stars,
The moon enfolds thee with her silver veil,
And o'er thee e'er is arched the rainbow's span, --
The gorgeous marriage-ring of Earth and Heaven.
While ever from the holy altar grand
Ascends the incense of the mist and spray,
That mounts to God with thy wild roar of praise
