This book is a collection of Jack London's short stories about his experiences sailing and seal hunting in the Pacific Ocean during the late 1800s. An additional adventure looks at life along the Sacramento River. The five showcased stories are adapted to increasingly higher reading levels--from 6.2 to 9.8 on the Flesch-Kincaid Reading scale. Maps, drawings, and photographs help bring alive the age of sailing and the courage of young sailors. A special section describes and illustrates the different types of sailing vessels, and a glossary and footnotes help the reader understand nautical terms.
