'Thus far, no farther, shalt thou go; and here
Shall thy proud waves be stay'd:'—A point at first
It peer'd above those waves; a point so small,
I just perceived it, fix'd where all was floating:
And when a bubble cross'd it, the blue film
Expanded like a sky above the speck;
That speck became a hand-breadth; day and night
It spread, accumulated, and ere long
Presented to my view a dazzling plain.
White as the moon amid the sapphire sea;
