Goes back and forth

Usage examples of sways.

I examine the earth, the air, the ocean, the heaven: I find that all have a mystic sympathy with each other--that the moon sways the tides--that the air maintains the earth, and is the medium of the life and sense of things--that by the knowledge of the stars we measure the limits of the earth--that we portion out the epochs of time--that by their pale light we are guided into the abyss of the past--that in their solemn lore we discern the destinies of the future.
