Prepare to overreach

Prepare to exhibit!

Pretentious pseudo-biblical title ready?

Check, "Illinois Stories: 'How Vast and Varied a Field' ... The Agricultural Vision of Abraham Lincoln."

Tangential and irrelevant artifacts ready?

Check, ox yoke and John Deere tractor prepared for show.

Rationale ready to explain how a farmer who abandons the land remains an agronomist?

Check, all Whigs are actually agronomists:
He recognized how technological and industrial advancements could improve agricultural productivity; how improved roads and canals and new rail lines could tie outlying markets to burgeoning cities; how national banks and a new currency system could help both farmers and businessmen.
