KIRKUS REVIEW

In this latest Junior Research book, the author discusses the ""treasures"" -- rocks, gem minerals, metals, crystals, fossils, etc. -- in brief readable terms. Rocks are first in order, and described most thoroughly; the various tests for determining a type of rock or mineral are carefully defined. An informative general introduction. Black and white pencil sketches are clearly instructive.
