Through The Looking Glass by Lewis Carroll Chapter 4 Page 9

No cloud was in the sky:

No birds were flying over head —

There were no birds to fly.

The Walrus and the Carpenter

Were walking close at hand;

They wept like anything to see

Such quantities of sand:

“If this were only cleared away,”

They said, “it would be grand!”

“If seven maids with seven mops

Swept it for half a year,

Do you suppose,” the Walrus said,

“That they could get it clear?”
