Hourglass:

Slowly, slowly
The sands of time,
Gather in the center
And begin their slide.

Slowly, slowly
Each slips further down,
One after another
Round and round.

Slowly, slowly
When time's just right,
They reach the hole
And fall out of sight.

Slowly, slowly
They all settle below,
And blend together
From the constant flow.

Slowly, slowly
The sand pile expands,
With the turning of
The minute hand.

Slowly, slowly
With time running down,
The last few grains
Fall to the ground.

Slowly, slowly
An hour did pass,
Says the dormant sands
Of the Hourglass.
