A Lincoln speech to the Wisconsin Agricultural Society, rearranged as free verse. Ripped from the Bird Dog.

Every blade of grass is a study;
And to produce two,
Where there was but one,
Is both a profit and a pleasure.
And not grass alone;
But soils, seeds, and seasons
Hedges, ditches, and fences,
Draining, droughts, and irrigation—
Plowing, hoeing, and harrowing—
Reaping, mowing, and threshing—
Saving crops, pests of crops, diseases of crops,
And what will prevent or cure them—
Implements, utensils, and machines,
Their relative merits,
And [how] to improve them—
Hogs, horses, and cattle—
Sheep, goats, and poultry—
Trees, shrubs, fruits, plants, and flowers—
The thousand things
Of which these are specimens—
Each a world of study within itself.
