This is a reprint of a time-tested history of Yosemite National Park by one of its most respected historians. It portrays in terms of human experience the growth of a distinct and unique conception of land management, and chronicles the thoughts and efforts of those who contributed to it. It tells of the obstacles overcome and of the pressures to break down the park concept and turn Yosemite to commercial and other ends that would deface its beauty and impair its significance. For these reasons, the book is more than a history. It traces the evolution of an idea.

Includes section "Book reviews."

The Centers for Disease Control and Prevention (CDC) established the Vessel Sanitation Program (VSP) in the 1970s as a cooperative activity with the cruise ship industry. The program assists the cruise ship industry in fulfilling its responsibility for developing and implementing comprehensive sanitation programs to minimize the risk for acute gastroenteritis. Every vessel that has a foreign itinerary and carries 13 or more passengers is subject to twice-yearly inspections and, when necessary, re-inspection.
