The Economist:

AN ODDITY has hidden for nearly a century in a dusty bowl just east of the Sierra Nevada mountains in California. Deep Springs is a two-year college and, also, a cattle-and-alfalfa ranch. Its 26 students share duties irrigating fields and riding the herd, but also fixing boilers and scrubbing pots, alongside reading Nietzsche and swotting at their maths problems. They pay no tuition fees, and most finish their bachelor’s degrees at Harvard, Yale and the like.
And they are all male. The college has admitted no women as regular students since it was founded in 1917, in accordance with a trust established by Lucien Nunn, the tycoon who founded it as a place “for promising young men”. The atmosphere is intellectual, rugged and ascetic, and the college is a democratic body, where student-led committees decide admissions, hire the faculty and mind most matters of policy.
