Cotton remained a key crop in the Southern economy after emancipation and the end of the Civil War in 1865. Across the South, sharecropping evolved, in which landless black and white farmers worked land owned by others in return for a share of the profits. Some farmers rented the land and bore the production costs themselves. Until mechanical cotton pickers were developed, cotton farmers needed additional labor to hand-pick cotton. Picking cotton was a source of income for families across the South. Rural and small town school systems had split vacations so children could work in the fields during "cotton-picking."
Besides adults what segment of the southern US population was involved in school systems?
A: unanswerable

Feminist economists Ailsa McKay and Margunn Bjrnholt argue that the financial crisis and the response to it revealed a crisis of ideas in mainstream economics and within the economics profession, and call for a reshaping of both the economy, economic theory and the economics profession.

The Latin phrase on Northwestern's seal, Quaecumque sunt vera (Whatsoever things are true) is drawn from the Epistle of Paul to the Philippians 4:8, while the Greek phrase inscribed on the pages of an open book is taken from the Gospel of John 1:14: (The Word full of grace and truth). Purple became Northwestern's official color in 1892, replacing black and gold after a university committee concluded that too many other universities had used these colors. Today, Northwestern's official color is purple, although white is something of an official color as well, being mentioned in both the university's earliest song, Alma Mater (1907) ("Hail to purple, hail to white") and in many university guidelines.
Why did Northwestern replace it's original official colors of black and gold?
A: too many other universities had used these colors
