To make a prairie it takes a clover and one bee — Prairie Fever

To make a prairie it takes a clover and one bee,
One clover, and a bee,
And revery.
The revery alone will do,
If bees are few.

In the prairie territories of America there is experienced by the traveller and the hunter, a strange sensation which has been called the prairie fever. It is a sweet and exhilarating feeling, absorbing for a time all recollection of the past, and killing all anxiety about the future. It is a maddening enjoyment of the present, arising from lightened spirits, and the grandeur of surrounding nature. ─ Our Garrisons in the West (1864)

The prairie fever! Yes. I was just then in process of being inoculated by that strange disease. It grew upon me apace. The dreams of home began to die within me; and. with these, the illusory ideas of many a young and foolish ambition. ─ The Scalp Hunters (1851) By Mayne Reid
