In my day (DS69), this book was sent to incoming students as an introduction to the background and philosophy of Deep Springs. It contains essays, a copy of the Deed of Trust, and a selection of letters between LL Nunn and the DS Student Body.
This book was published by Telluride Association shortly after LL Nunn's death in 1925, in an attempt to summarize the philosophies of the institutions. It went through several editions. A number of interesting early photos of Deep Springs.
