The Mercer Boys (#3) on a Treasure Hunt

the long version

Don and Jim Mercer are prepared to spend a dull vacation at home - until Prof. Scott invites them to search for Spanish gold buried treasure, in Southern California, where they soon found themselves surrounded by another (but ruthless) group of treasure hunters! Albert Capwell Wyckoff was born on February 21, 1903, in New Jersey. His father, also named Albert Capwell Wyckoff, died when his son was young, an event that forced Capwell to go to work. He never finished high school, yet Capwell Wyckoff became a successful author of two and a half dozen children's novels.
