Two Butterflies went out at Noon

Two Butterflies went out at Noon
And waltzed opon a Farm
And then espied Circumference
And caught a ride with him —
Then lost themselves and found themselves
In eddies of the sun
Till Gravitation missed them —
And Both were wrecked in Noon —
To all surviving Butterflies
Be this Fatuity
Example — and monition
To entomology —
